Senior Software Engineer (Java) | Enterprise SaaS | Architecture, Scale & Technical Leadership

Are you a Senior Java Engineer who wants more than just another backlog of tickets?

This is an opportunity to join a high-growth Australian SaaS company whose platform powers critical business processes for major enterprise customers across global markets.

You'll be part of a highly collaborative engineering team responsible for evolving a complex, large-scale platform, solving challenging technical problems, influencing architecture decisions, and helping shape the future direction of the product.

If you enjoy building scalable software, mentoring others, and having genuine input into technical strategy, this is the type of role where you'll make a visible impact.

The Opportunity

As a Senior Software Engineer, you'll play a key role in designing, building and enhancing a sophisticated enterprise platform used by some of the world's largest organisations.

Working closely with Product, Engineering and Delivery teams, you'll contribute to technical design, drive engineering best practices, and help ensure the platform remains secure, scalable and resilient as it continues to grow.

• Solving complex engineering challenges across a mature enterprise SaaS platform
• Driving improvements in software quality, performance, reliability and maintainability
• Reducing technical debt and championing continuous improvement initiatives
• Contributing to architectural discussions and influencing technical direction
• Collaborating closely with cross-functional teams to deliver customer-focused outcomes
• Supporting production systems and ensuring reliable platform performance
• Mentoring developers and helping elevate engineering standards across the team
• Contributing to a strong engineering culture built on collaboration, ownership and continuous learning

Tech Environment

You'll bring experience across many of the following:

• Java
• Spring Framework
• Hibernate / JPA
• REST APIs
• SQL Server, PostgreSQL or Oracle
• Maven or Gradle
• Git
• CI/CD pipelines
• Enterprise application architecture
• Distributed systems and integrations

What We're Looking For

• Around 7+ years of commercial software engineering experience
• Strong expertise building applications with Java and JVM technologies
• Experience designing scalable, secure and maintainable software solutions
• Strong understanding of software architecture, design patterns, SOLID principles and clean code practices
• Experience working with enterprise-scale systems and complex integrations
• Strong database knowledge and API development experience
• Ability to communicate technical concepts clearly to both technical and non-technical stakeholders
• A collaborative mindset with experience mentoring and supporting other engineers
• Someone who enjoys taking ownership and solving meaningful technical challenges

Why This Role Stands Out

• High-impact engineering work on a sophisticated enterprise platform
• Opportunity to influence architecture and technical direction
• Strong engineering leadership and collaborative culture
• Modern software engineering practices and continuous improvement mindset
• Complex technical challenges that will stretch and develop your skills
• Long-term career growth opportunities within a successful SaaS business
• A team that values quality engineering, ownership and innovation

If you're a Senior Java Engineer looking for a role where you'll have genuine influence, solve interesting technical problems and work alongside experienced engineers who care about building great software, I'd love to have a confidential conversation.

Some data scientists want to publish papers. Some want a FAANG logo on their CV. Others just want to explain their work simply at a dinner party.

For years, data science was a business support function running analyses for "the business". Supporting decisions made elsewhere.

Data science now drives product decisions. People are building systems customers depend on daily, embedding them into core workflows, and investing heavily in measurement and governance. They need a leader to own it.

You'll report to the VP, who is based in the US, but you'll own the strategy and impact of a portfolio of data science work across multiple teams.

And establish governance for AI, data quality, privacy, and model risk. Lead and develop strong managers and senior ICs.

We need someone with 12+ years in data science and proven experience leading managers and operating at enterprise scale.

You've led multiple teams through large strategic programs. You've built platforms or standards that materially improved organisational leverage.

You have strong strategic judgment, excellent executive communication, and the ability to build alignment across senior leaders.

Experience in product, B2B SaaS, or leading responsible AI adoption is highly desirable.

Melbourne or Sydney. Hybrid (1-2 days/week onsite).

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.

Senior Embedded System Engineer

Sydney | Full-time | Hybrid | $130k-160k + super

The Scroll-stopper

Most senior embedded roles ask you to own firmware.

This one asks you to own the bit where hardware, software and product collide.

A rare opportunity for hands-on exposure to emerging technology; including edge AI accelerators and high-end sensor hardware.

The Org

A small, elite team in Sydney is building a modular wireless sensing platform that spans embedded devices, edge compute, cloud infrastructure and customer-facing applications. The hard part is not writing firmware in isolation. It is figuring out how new capabilities get added, how new sensors get integrated, and how the whole thing stays coherent as the product scales.

You’ll be an early member of a growing engineering team, at one of the Aussie ecosystem's most promising startups. A startup with fresh funding, international clients, and a unique product. A unique product built for a problem space vital to modern life.

You'll work closely to the CTO, and take ownership of the embedded layer across a platform that is already live, already useful, and ready to become much more capable.

The Mission

This is not a narrow firmware seat buried in a backlog.

You’ll sit in the layer between low-level device behaviour and real product capability.

One week you’re bringing up a new sensor.
The next you’re building the Linux-side application that makes its data usable.
Then you’re tracing why something broke three layers upstream.

Whatever your week looks like, your work will contribute to human safety and shield society from immense pressure.

What You’ll Work On

• Build embedded capabilities across a modular wireless sensing platform
• Write Python and C/C++ across Linux and bare-metal environments
• Integrate new sensors from hardware interface through to system output
• Build low-level Linux applications that move data through the stack
• Support firmware, system integration and device-to-cloud data flow
• Work across hardware, software and product to ship new capability fast

What Matters Here

• Strong Python
• Strong C/C++ in Linux
• Working competence with bare-metal C
• Comfortable in low-level Linux environments
• Able to work across hardware, firmware and software layers
• Comfortable reading schematics, bringing up boards and debugging real systems
• Curious, self-directed and happy solving problems that do not arrive neatly labelled

Bonus points for

• ESP-IDF
• Wireless sensor systems
• Debian (ideally Bookworm)
• Raspberry Pi ecosystm (particularly Compute Modules)
• AWS IoT Core or Greengrass
• GStreamer, OpenCV or imaging pipelines

Why It’s Worth Your Time

This is not one of those embedded jobs where you inherit a driver stack and spend three years shaving milliseconds off the same problem.

It's broader.
It's higher impact.
It's more interesting the deeper you go.

Oh look, you're still reading.
