Help rebuild the core technology platform of an established Australian Fintech.

We're partnering with an established Australian Fintech that's investing heavily in its engineering capability and undertaking a major technology transformation.

With an impressive new technology leadership team bringing experience from some of Australia's leading technology companies and high-growth scale-ups, they're looking for a Staff Software Engineer to help shape the next generation of their platform.

This is an opportunity to join at a point where significant architectural decisions are still being made, with genuine ownership over how the technology evolves.

The Opportunity

You'll be one of the most senior hands-on engineers in the business, working closely with engineering leadership to build new backend systems and progressively modernise a complex existing platform.

The focus is on building scalable, reliable systems across lending, credit and payments, while helping establish a stronger internal engineering function.

What you'll be doing:

• Designing and building backend services using Node.js, TypeScript and AWS.
• Architecting scalable distributed systems, APIs and event-driven services.
• Modernising legacy applications and integrating new systems with existing infrastructure.
• Driving technical decisions around architecture, scalability, reliability and performance.
• Establishing engineering standards, best practices and development processes.
• Remaining hands-on while mentoring engineers and influencing technical direction across the business.

What We're Looking For

• Strong commercial experience with Node.js and TypeScript, particularly backend engineering.
• Deep hands-on experience with AWS and designing cloud-native applications.
• Experience building complex distributed systems, microservices and event-driven architectures.
• Strong understanding of API design, integrations, system performance and reliability.
• Experience modernising legacy platforms or delivering significant technology transformations.
• Proven experience operating at Staff, Principal or hands-on Technical Lead level.
• Excellent communication skills, technical judgement and the ability to work through ambiguous problems.

Experience in Fintech, payments, lending or banking would be highly regarded, but isn't essential.

Why Consider the role?

• Genuine technical ownership: Help shape the future architecture rather than simply deliver against an existing roadmap.
• Experienced leadership: Work directly with senior technology leaders who have built and scaled engineering teams in successful technology businesses.
• Meaningful engineering challenges: Complex backend systems, distributed architecture, new platform development and legacy modernisation.
• Stay hands-on: A senior individual contributor position without the expectation of moving into people management.
• Long-term impact: Play a key role in building a stronger engineering function and setting its technical foundations.

Location: Sydney CBD — five days in the office during probation, moving to four days afterwards.

If you're a senior backend engineer who enjoys solving complex technical problems, working with strong engineering leaders and having real influence over architecture, we'd love to hear from you.

Head of IT & Infrastructure | Sydney

Take complete ownership of IT and infrastructure for a fast-growing technology business.

We're partnering with a rapidly scaling technology company where software, hardware and advanced engineering come together.

This is an opportunity for a hands-on infrastructure leader to take full ownership of the systems keeping the entire operation running, from complex networking, cloud and security through to the specialist infrastructure supporting engineering and production.

The business is growing quickly and needs someone who can bring structure, improve reliability and build an infrastructure environment capable of supporting that growth.

You'll have the autonomy to make technical decisions, shape the long-term infrastructure roadmap and build out the IT function as the business expands.

What You'll Be Working On

• Networking: Own the design and operation of the network environment, including switching, routing, VLANs, firewalls, VPNs and network segmentation.

• Infrastructure: Manage Linux and Windows environments, servers, virtualisation, storage, backups and disaster recovery.

• Cloud: Support and improve AWS, DigitalOcean and on-premise infrastructure, with a focus on reliability, security and automation.

• Engineering Systems: Maintain the infrastructure supporting technical teams, including compute resources, CI environments, storage and specialist equipment.

• Strategy & Ownership: Take responsibility for infrastructure planning, vendors, budgets, documentation and scaling the IT function.

What We're Looking For

We're looking for someone with broad technical capability who has experience taking ownership of infrastructure across a business, rather than specialising in just one area.

The key things we're looking for:

• Excellent networking fundamentals, including hands-on experience configuring switches, routing, firewalls, VLANs and troubleshooting network issues.

• Broad systems administration experience across Linux, Windows, virtualisation and storage.

• Strong Microsoft identity experience, including Entra ID, Active Directory and hybrid environments.

• Experience managing cloud infrastructure, ideally AWS, alongside on-premise systems.

• Scripting and infrastructure automation experience.

• Good security fundamentals across identity, access, endpoints and infrastructure.

Why Consider This Opportunity?

• Genuine ownership: Take responsibility for how the entire IT and infrastructure environment operates and evolves.

• Build and improve: Design new solutions, modernise existing systems and introduce better ways of working.

• Technical variety: Work across networking, cloud, infrastructure, security and specialist systems rather than being limited to one technology.

• Autonomy: Make decisions, solve problems and shape the future infrastructure environment.

• Growth: Join a scaling business with the opportunity to build and lead a team as the company expands.

• Equity: Competitive base salary plus company equity.

Senior Robotic Systems Integration Engineer

How do you deploy humanoids at scale when each one still needs an engineer beside it?

That’s the next problem for this robotics startup.

The team has built the core capabilities. Robots are moving into real customer environments. Now the work is making those behaviours reliable enough to repeat, understanding why they fail, and building a way to deploy them without sending the engineering team along every time.

You’ll own that transition.

The engineering challenge

A behaviour works in testing. You release it. In the field, the robot stops short of where it should.

You’ll need to work out whether the problem sits in perception, planning, control or the way those pieces interact. More importantly, you’ll make sure the next run captures enough evidence to find the answer.

Working alongside ML and robotics engineers, you’ll take new capabilities through testing and into deployment. Your decisions will shape what gets released, what needs more work, and what the team fixes next.

What you’ll own

• Define release criteria and repeatable tests that show how a behaviour performs and where it breaks.

• Get hands-on with the codebase and hardware to diagnose failures across the robotics stack.

• Build logging and review tools that let engineers investigate field issues without standing beside the robot.

• Turn failed runs into clear engineering priorities, then work with the original developers to ship improvements.

• Develop the metrics and deployment practices needed to track performance and roll out changes across a growing fleet.

There’s plenty still to build. You’ll have room to shape the approach, including the judgement to start with a useful manual process and automate it once you understand what works.

What you’ll bring

You’ve worked on real robotic systems and followed problems across hardware and software. You can read the code, question the behaviour, and keep investigating until you have a useful explanation.

ROS 2, perception, planning and control should be familiar ground. So should working through bag files and logs to understand what actually happened.

Experience with field deployments, fleet operations or rolling out robot updates would be especially useful. If your deployment experience is smaller, we’ll want to understand how you’d make it repeatable as the fleet grows.

You might come from a startup, a larger robotics business or a research team that puts systems into the field. What matters is what you’ve personally built, debugged and taken responsibility for.

Why join now?

You’ll join while the team is establishing how its robots will operate beyond closely supervised deployments. The testing and release decisions you make now will influence how the product scales.

It’s a small team working closely with physical hardware, so expect to be in the office most days, with occasional flexibility. You’ll have direct access to the engineers building the capabilities and the opportunity to see your changes tested on the robot.

• Own renewals, regular check-ins and annual partner reviews.
• Monitor account health, address risks early and share partner feedback with internal teams.
• Visit partners regularly and represent the business at partner and industry events.

About You

You bring at least three years of experience in account management or customer success, ideally with ownership of retention, renewal or growth targets.

You’re someone who earns trust, stays organised and follows through. You’re comfortable talking with senior stakeholders, guiding customers through change and balancing several accounts and launches at once.

You’ll also bring:

• A commercial mindset and the ability to turn opportunities into results.
• Strong written and verbal communication.
• Attention to detail and good CRM habits.
• Initiative and confidence working in an evolving business.
• A Melbourne or surrounding-area base and willingness to travel regularly.
• Experience in payments, fintech or SaaS would be a bonus.
