About the role
Kustomer is hiring a Full Stack Software Engineer to join our Engineering team. In this role, you'll work as part of a pod: a 3–5 person team that picks up a high-priority initiative, ramps quickly, ships end-to-end, and moves on to the next one. You'll be a capable, adaptable engineer who can walk into any part of the codebase, understand it, and make it better.
What they're looking for
- 7+ years of progressive software development experience and a Bachelor's degree in Computer Science, Software Engineering, or a related field
- You're comfortable working across frontend and backend. You may have a stronger side, and that's fine. What matters is that you can follow the work wherever it goes and aren't blocked by an unfamiliar layer
- You understand how systems work at depth and have experience with cloud platforms like AWS or similar. Data structures, algorithms, concurrency, distributed systems, API design, database internals, these are tools, not trivia
- You don't need to be the domain expert before contributing. You read READMEs, trace execution, ask sharp questions, and start adding value fast
- You own the outcome, not just the ticket. You raise risks early, communicate progress proactively, and care about what ships, not just what you committed
- You’re able to diagnose and debug complex issues, optimize application performance, and identify areas for improvement
