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 without cutting corners.
• Keep stakeholders informed — communicating timing, trade-offs, and risks clearly enough that Product can make good decisions, not just hopeful ones.
• Raise the bar for the engineers around you through thoughtful code reviews, honest feedback, and genuine knowledge sharing.

What you should bring with you

• Strong TypeScript skills and comfort using it across the stack — from back-end services and APIs to front-end interfaces.
• Real experience with cloud infrastructure (AWS preferred) and a comfort designing and operating distributed, event-driven systems.
• Solid back-end fundamentals — database design, API architecture, and the kind of systems thinking that comes from owning services end to end.
• Front-end experience, ideally with React, and the ability to build interfaces that integrate cleanly with the services behind them.
• The kind of judgment that comes from having redesigned or migrated a production system and lived to tell the story.
• Comfort using AI tools as part of your daily workflow — for writing, reviewing, and thinking through design problems.
• A practice of "kind engineering" — well-documented, well-tested code that's a genuine pleasure for the next person who touches it.
• A curious nature and the drive to keep getting better at this craft, even when you're already good at it.
