Full Job Description

Senior Software Engineer - Full Stack Have you ever caught yourself mentally redesigning a system you use every day — not because it's broken, but because you can see exactly how it could be better? Yeah, us too. At Fixify, we believe the best engineering isn't just about building things that work — it's about building things that work for people. We're in the middle of some of the most meaningful platform work in our company's history, and we need a Senior Software Engineer who gets energized by the hard stuff: rearchitecting systems without breaking them, making complex problems feel simple, and shipping changes that users feel but never have to think about. You'll own work across the full stack equally — back-end services, cloud infrastructure, and front-end interfaces — and you'll use AI tools as a natural part of how you build and review. You'll bring the kind of judgment that knows when to move fast and when to slow down, and you'll keep the people around you informed, unblocked, and better at their jobs. At a startup this size, you'll see the impact of every decision you make — including the ones you agonized over at 2pm on a Tuesday. What we can do for you Give you ownership of platform work that actually matters — not just feature tickets. Put you on a team that takes engineering discipline seriously without taking itself too seriously. Connect you directly with the people who use what you build, so the feedback loop is real. Give you room to mentor, lead technical efforts, and shape how the team works — not just what it ships. Share the "why" behind every decision so you grow from the whole journey, not just your piece of it. What you can do for us Take ownership of evolving our platform safely — managing the messy middle between what exists and what needs to exist. Build across the stack — back-end services, cloud infrastructure, and React front-end — and make it all feel coherent. Use AI tools to write better code, catch problems earlier, and move faster
