Job Description

Senior Full Stack Engineer (Backend Focus - Java)

🏠 Hybrid – 50/50 split

💰Up to $170K+Super

We’re looking for a senior engineer who’s strongest on the backend but happy to dip into full stack when needed. You’ll split your time between our customer engineering team and our platform team-jumping in where you can have the most impact.

This is the hiring manager’s first role in this space, so it’s a big one. You’ll have the chance to set the tone for how we build, raise the bar on quality, and help shape the team culture as we grow.

Day-to-day, you’ll be working on a Java-based SaaS platform that powers multiple customer products. You’ll get stuck into building new features, fixing tricky performance issues, and making smart architecture decisions. If you’re interested, there’s a clear path here to Team Lead or Principal Engineer- but you can stay deep in the tech if that’s your thing.
