Senior Software Engineer

Senior Software Engineer(Java/Kotlin, Spring Boot, AWS) | Remote-first | Regulated SaaS

We’re back in the saddle helping our good mates Biza.io through their next phase of growth - and this time, it’s all about backend firepower!

If you’re an engineer who thrives in complexity, loves solving problems no one’s cracked before, and is ready to level up your backend game in a scale-up doing seriously meaningful work - read on.

Because Biza’s engineering team? They don’t just ship features. They architect the future of open data.

First, a bit about Biza.

Biza.io is the infrastructure behind Australia’s Consumer Data Right (CDR) - a consent-led data-sharing framework built to give consumers real control of their personal data.

Think Open Banking… but bigger.

Biza helps banks, fintechs, and energy providers securely plug into the CDR, offering API-led SaaS solutions that simplify the mind-bending compliance puzzle of this emerging space.

They’re deep in the tech, influencing regulation, and powering the open data movement from behind the scenes.

And while their clients are some of the country’s biggest names, the engineering team is still lean, senior, and founder-led. Which means real ownership. Fast learning. And major impact from day one.

The work you’ll be doing

This isn’t your typical CRUD app job.

You’ll be working across a multi-tenant architecture with hefty security, performance, and compliance demands. Most of your work will live in the backend - but you’ll need to think well beyond the code.

You’ll:

• Design and deliver backend services using Java/Kotlin + Spring Boot
• Solve complex integration problems across financial and energy APIs
• Collaborate with Product and Customer Success to turn real-world regulatory needs into elegant software solutions
• Apply secure-by-design and privacy-first engineering practices
• Help shape the architecture and scalability of Biza’s core platform as it continues to grow
• Share ideas, pair up, and help other engineers level up - you’ll be surrounded by smart people who want to do great work

There’s plenty of deep thinking here - not just about what’s being built, but why it’s being built that way.

You might be a fit if…

• You’re fluent in Java or Kotlin and comfortable in a Spring Boot environment
• You’ve built and scaled secure, high-availability backend systems before
• You’ve worked in a regulated space (banking, fintech, energy, healthcare)
• You’re experienced with cloud-based architecture - bonus points for AWS and some Azure
• You understand that compliance isn’t just red tape - it’s a design constraint and a business advantage
• You’re curious, collaborative, and confident thinking for yourself
• You don’t wait to be told what to do - you lean in, ask questions, and start untangling problems

Why engineers love Biza

• Remote-first across Australia’s East Coast. Work where you work best.
• Strong engineering culture: high trust, high standards, zero ego
• Founder-led with deep product vision + stable Series A backing
• You’ll report to the Director of Engineering and work alongside a Principal Engineer and high-seniority team
• Autonomy to build things the right way - not just ship and pray
• Access to truly novel engineering challenges - you’ll get to design from scratch, not just maintain legacy systems

This is a great time to join.

Biza is transitioning from startup speed to scale-up maturity - and you’ll be at the heart of that evolution.
