Senior Full Stack Engineer – Kotlin / Spring Boot / React

Sydney | Hybrid | 6-Month Day Rate Contract + Likely Extension

We’re partnering with a major Australian enterprise going through significant technology transformation, with a number of greenfield initiatives on the roadmap.

We’re looking for a strong backend-leaning Full Stack Engineer who enjoys solving complex problems, owning outcomes and working across the stack when needed.

The opportunity

You’ll work within a modern product engineering environment, building and evolving scalable applications while contributing to new greenfield development.

The backend is centred around Kotlin and Spring Boot, but this isn’t a purely backend role. You’ll need enough frontend capability to comfortably work across modern JavaScript applications, with TypeScript and React particularly relevant.

There’s also a strong focus on how engineers are harnessing AI tooling to improve the way they build software. We’re keen to meet developers already using tools such as Claude Code, Cursor, Copilot or coding agents to accelerate development, testing, debugging and delivery.

What we’re looking for

• Strong Kotlin / Java and Spring Boot engineering experience
• Genuine full stack capability, with a backend bias
• Exposure to JavaScript, TypeScript and/or React
• Experience building APIs, microservices and distributed applications
• Good exposure to modern AWS or GCP cloud environments
• Engineers actively incorporating AI tooling into their development workflows
• Strong problem-solving skills and the ability to take ownership from idea through to production
• Comfortable working within modern CI/CD and product engineering environments

Initial 6-month day rate contract with a strong likelihood of extension.

If you’re a hands-on engineer who enjoys difficult technical problems, modern technology and the opportunity to contribute to genuine greenfield development, I’d be keen to hear from you.

Marketing Manager, Partnerships | San Francisco | AI Infrastructure

Some partnership roles are about coordinating campaigns.

This one is about helping manage some of the most strategically important technology relationships in the AI infrastructure and GPU compute ecosystem.

I’m working with a high-growth global business looking for an experienced Technology Partnerships Marketer to join its San Francisco team.

This is a newly created role and a pivotal hire.

Around 60% of the initial focus will be dedicated to one major global GPU technology partner, alongside other significant relationships across hardware, infrastructure and enterprise technology.

We’re looking for someone who understands how sophisticated technology partnerships work from the inside.

Someone who knows how to navigate large global technology organisations, build relationships across multiple stakeholder groups and identify where genuine joint commercial and marketing opportunities exist.

You’ll own the marketing side of these partnerships, including:

• Building joint marketing and go-to-market strategies
• Developing and executing co-marketing programs
• Managing relationships across regional and global partner teams
• Identifying opportunities to unlock more value from strategic alliances
• Managing Market Development Fund proposals, approvals and utilisation
• Running regular partner business reviews
• Managing partner calendars and joint objectives
• Coordinating co-branded content and technical enablement
• Working closely with Sales and Product
• Supporting partner-hosted events and initiatives
• Tracking pipeline influence, spend and ROI

This isn’t a role where you’ll inherit a perfect playbook.

You need to bring experience, judgement and a strong point of view.

We’re particularly interested in people who have worked within or alongside major GPU, cloud, hardware or enterprise technology vendors and understand the complexity of these ecosystems.

And don’t be misled by the Marketing Manager title.

This is not a junior opportunity or a development move.

The business needs someone who has done this before, knows how to operate independently and can take ownership quickly.

📍 San Francisco
🤝 Strategic technology alliances
⚡ AI infrastructure and GPU compute
🌎 Global remit

If your career has been built around major enterprise technology partnerships and you know how to turn those relationships into meaningful GTM activity, this is well worth a conversation.  apply online or email Michelle Rubinstein at The Onset at michelle@theonset.com.au.

Marketing Manager, Events | San Francisco | AI Infrastructure

This one needs an events operator. Not someone ready to learn how to become one.

A fast-scaling business operating across AI infrastructure, GPU compute and global data centres is growing rapidly and they are looking for an experienced B2B Events Marketing professional to take ownership of a growing international events program.

The title says Marketing Manager. The remit is considerably bigger.

You’ll be responsible for looking at the global AI, GPU, cloud and data centre conference landscape and answering some fairly important questions:

Where should the business be showing up?
Which events actually matter?
Where should sponsorship dollars be invested?
What should the global events strategy look like over the next 12 months?

Then you’ll make it happen.  From strategy through to execution.

You’ll:

• Build and execute the events and sponsorship strategy across a growing global footprint
• Own flagship B2B conferences, sponsorships and brand activations end-to-end
• Develop business cases and manage healthy event budgets
• Work closely with Sales, Commercial, Product, Legal and Investor Relations teams
• Negotiate with conference organisers, venues and suppliers
• Manage everything from contracts and sponsorship rights through to stands, signage, executives and delegate experience
• Measure ROI and use performance data to shape future investment
• Build out the San Francisco events strategy and local technology community presence
• Support a global calendar spanning the US and Europe, with further expansion ahead

And there are plenty of unglamorous bits.

This is a business where everyone gets into the weeds, regardless of seniority. You won’t develop the strategy and hand execution to a large team underneath you.

You need to be comfortable doing both.

We’re looking for someone with strong B2B conference and events experience, ideally across enterprise technology, cloud, AI infrastructure, data centres or another complex technology environment.

You’ll need to be commercially sharp, exceptionally organised and strong enough with stakeholders to operate confidently across a fast-moving business.

Most importantly, you need to have done this before.

This isn’t a role with a long runway for learning.

📍 San Francisco
🏢 Hybrid, ideally around 3 days in office
🌎 Global remit

If you know how to turn an events budget into a genuine commercial and brand platform rather than simply a calendar of conferences I’d love to here from you.  Apply online or email Michelle at The Onset at michelle@theonset.com.au.

Delivery Manager – Technology

Sydney | Fintech | Hands-on Delivery

We’re partnering with an Australian fintech looking for a Delivery Manager to work closely with the CTO and bring greater structure, visibility and momentum across its Technology portfolio.

This isn’t a traditional PMO role. You’ll operate across Engineering and the broader business, taking sometimes loosely defined problems and turning them into clear, executable plans.

The role

You’ll be responsible for:

• Driving multiple technology initiatives from requirements through to production
• Coordinating Engineering and stakeholders across Product, Operations, Risk, Compliance, Sales and Marketing
• Creating clear plans, milestones, dependencies and delivery visibility
• Identifying risks and resolving blockers before they impact delivery
• Supporting quarterly Technology planning and prioritisation
• Improving delivery practices and ways of working without adding unnecessary process
• Using Jira and Confluence to maintain visibility and accountability

What we’re looking for

You’ll have:

• 5+ years’ experience in Technology Delivery, Project or Program Delivery
• Strong end-to-end technology delivery experience
• Enough technical understanding to work confidently with Engineering
• Experience managing multiple initiatives and competing priorities
• Strong stakeholder management across technical and business teams
• The ability to work through ambiguity and create structure where it doesn’t already exist
• A pragmatic approach to Agile, Waterfall or hybrid delivery

Experience across fintech, lending, banking, payments or financial services is a must. Salesforce exposure would also be valuable.

Why join?

This is an opportunity to work directly with the CTO, take real ownership and influence how Technology delivery operates.

There’s no large PMO or rigid playbook to inherit. You’ll have the autonomy to introduce the right level of structure, stay close to the technology and help build a stronger delivery capability as the business evolves.

If you enjoy bringing clarity to complexity and getting technology initiatives moving and comfortable to be in the office 5 days a week, we’d love to hear from you.

Marketing that actually gets close to the business.

We’re The Onset - a specialist recruitment business deeply connected to Australia’s technology ecosystem. We work with ambitious companies, brilliant industry experts and a wider group of specialists across data, AI, design and transformation through The Omnia Collective.

We’re growing our marketing team and looking for someone who wants more than a narrow coordinator role. You’ll help us build smarter campaigns, experiment with AI and automation, support client engagement, work across the wider Omnia group and get involved in the events and experiences that bring our community together.

It’s a broad role by design. One day you might be building a target-account campaign with a recruitment leader; the next, testing an AI workflow, helping activate an industry event or pulling together the data that tells us what is actually working.

What you’ll get stuck into

• Build targeted B2B campaigns around the clients, sectors and communities we want to engage.

• Experiment with AI and automation to make research, campaign delivery, follow-up and reporting smarter.

• Work closely with our recruiters on client outreach, useful market content, case studies and sales enablement.

• Coordinate website, SEO/AEO/GEO, email and digital activity and help us turn performance data into better decisions.

• Become a key link between The Onset and Omnia Collective, working alongside teams across AI, data, design and transformation.

• Help deliver client, community and industry events - from the campaign and guest experience through to the practical set-up and follow-up.

• Keep the marketing engine organised: systems, assets, reporting, campaign workflows and the details that make good ideas happen.

You’ll thrive here if…

• You have some marketing experience under your belt - ideally in B2B, growth, campaigns or marketing operations - and you’re ready for more ownership. Technology sector, recruitment or professional-services experience is useful, not essential.

• You are already using AI as a marketing and productivity tool. Maybe you use ChatGPT or Claude every day, have built agents and automations, or are the person who always asks, “could we make this easier?”

• You like working close to sales and clients and can see the difference between useful engagement and marketing noise.

• You are organised enough to keep multiple things moving, but curious enough to keep improving how they are done.

• You are comfortable with digital tools and data, without needing to be a technical specialist.

• You have a hands-on style. We are a small team: no one is too senior to help set up a room, move a box, capture content or solve the thing that needs solving.

• You enjoy people. This role crosses recruiters, leaders, clients, community members and teams across the wider Omnia group.

Why this one is interesting

• You’ll work alongside our Brand & Community Specialist, with room to build complementary expertise in growth, AI and marketing operations.

• You’ll have access to experts across Onset and The Omnia Collective and exposure to the way AI, data, design and transformation are changing businesses.

• You’ll work directly with senior leaders and recruitment consultants rather than sitting several layers away from the commercial conversation.

• You’ll get genuine variety: campaigns, AI, events, content, systems, client engagement and community.

• There is a clear path to grow as your ownership and capability expand.

• We offer a flexible WFH day, ongoing development, team events and a lively Surry Hills office environment.

A note on experience

We care more about capability, curiosity and attitude than finding someone who has done this exact job before. If you have a strong marketing foundation, like learning new technology and want to be close to the action in a growing business, we would like to hear from you.

Interested?

Send us your CV and tell us a little about what caught your attention. If you have built something interesting with AI, run a campaign you are proud of or found a smarter way to solve a marketing problem, we would love to hear about that too.

Senior Engineer – Practice Lead | Global Financial Services | Sydney

If you're a Principal or Lead Engineer in platform or DevOps, and you're tired of being the person holding everything together while everyone else goes home. This is worth reading.

A globally recognised financial services organisation is looking for someone to own its Telemetry and Analytics practice. That means platform and product ownership of enterprise-scale SIEM and threat intelligence platforms, a live and varied project pipeline, and a small, high-trust team that actually has its act together.

The person who held this role for the past two years told us it's the first job they've had in years where they weren't online every weekend dealing with something platform-related. The support infrastructure here is real. You're not carrying it alone.

What you'll be working on

There's a solid pipeline of technical work ahead. A credential management overhaul spanning source code, pipelines, and release infrastructure; a vendor platform migration; new platform delivery; and active POCs in flight. It's genuinely varied, and it's hands-on. You'll be designing, integrating, and developing platforms rather than babysitting them.

Day to day you'll be working across IaC, CI/CD pipelines, containerisation, and scripting. Building and maintaining the infrastructure that underpins security operations at enterprise scale. You'll work closely with a small, experienced team across Australia and the US, and interface with detection engineers, analysts, and senior stakeholders globally.

What this does for your career

The brand carries weight. Two years here, owning platforms at this scale, delivering complex projects, and operating within a world-class financial services environment is a credible and visible step toward a Director or Principal Architect role. The person before you used it exactly that way.

What you'll bring

A strong DevOps, platform, or release engineering background. Solid hands-on experience with IaC (Terraform, Puppet, or Ansible), CI/CD pipelines, Kubernetes, and Linux. Proficiency in Python or Shell. You've worked in an enterprise environment, financial services, insurance, banking, or similar scale and complexity. And you're fluent in governance and compliance without being slowed down by it.

You don't need a security specialism. If you've operated SIEM, log pipelines, or observability platforms from a platform engineering angle, that experience is relevant. You will grow your domain knowledge with this role.

Hit apply or send me a message and I'll get you the full brief.

Staff Site Reliability Engineer - $300k (base + super + bonus), Sydney - 2 Days WFH

You join the team.

You learn the systems. You find the problems. You write the docs.

You give the talk, but nobody listens.

3am pages. Same alert. Different week.

You know the fix. It's just not prioritised.

You're a Staff SRE. You've got the answers. You've got the experience.

You're just not being asked to use them.

Most experienced SREs reach a point where keeping systems alive stops being the challenge.

What's exhausting is watching the same reliability problems repeat, because nobody prioritises the work that would prevent them.

As the foundational Staff SRE here, it would be different.

You're not here to own incidents. You're here to eliminate the reasons they happen.

The hiring manager's view is that reliability has no shortage of good ideas, they're just rarely prioritised.

This role exists to change that.

You'll have genuine influence over OKRs, engineering standards, and how reliability is measured across an organisation of 1,500 engineers.

That's not a common thing to be offered.

This is their first Staff SRE hire.

That means you'll define what the role means inside one of Australia's largest engineering organisations.

The impact you need to reach Principal is here.

You'll also shape their Agentic SRE strategy. AI applied to incident detection, diagnosis, and remediation. Not a pilot. In production.

For engineers who want to understand where the discipline is heading over the next decade, joining now means building that experience rather than reading about it in someone else's case study.

If you've been doing strong Staff-level work but feel like you're spending more time firefighting than fixing things, then send me a message.
