Job Description
Senior Full Stack Engineer (Backend Focus - Java)
Hybrid – 50/50 split
Up to $175K+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.
Why you might like this role
* You’ll work across both customer and platform engineering, so you’ll always have interesting problems to solve.
* You’ll get to bring fresh ideas on how we build software and make them happen.
* You’ll work closely with other senior engineers, team leads, and product folks who actually value your input.
What You’ll Be Doing
* Taking ownership of projects from the idea stage right through to delivery and improvement.
* Building, refactoring, and tuning systems in Java, Docker, Postgres (and sometimes React).
* Figuring out whether something’s a platform problem or a product bug - and fixing it the right way.
* Helping other engineers level up through mentoring and knowledge sharing.
What We’re Looking For
* Strong experience with Java-based SaaS platforms and backend work.
* Solid architecture skills and the ability to spot problems before they blow up.
* A track record of shipping real, complex projects.
* Someone who naturally steps up to guide others and improve the way the team works.
