Join to apply for the Senior Software Engineer role at The Onset 2 days ago Be among the first 25 applicants Join to apply for the Senior Software Engineer role at The Onset Job Description Senior Full Stack Engineer (Backend Focus - Java) Hybrid – 50/50 split Up to $175KSuper 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. Sound like a fit?
