Role & Responsibilities
Take end-to-end ownership of critical backend services — from architecture and development to deployment and scale.
Design systems for performance, reliability, and observability. Identify bottlenecks and eliminate them proactively.
Collaborate with product and design to deeply understand user pain points and build the right solutions.
Work independently and own complex modules with minimal oversight.
Champion clean, maintainable code and help set a high bar for engineering excellence across the team.
Stay up-to-date with new tools, technologies, and backend trends — and bring the best ideas into our stack.
Ideal Candidate
2+ years of backend development experience, ideally with Kotlin and Spring Boot (or willingness to ramp up quickly).
You’ve worked in fast-moving teams and thrive when given room to figure things out.
You take initiative and can drive complex modules to completion without needing constant guidance.
Strong with both low-level and high-level design; you know how to build scalable, reliable RESTful APIs.
Proficient with relational databases and aware of common performance pitfalls.
Confident with debugging and optimizing — memory leaks, latency issues, and other hard-to-find problems don’t scare you.
You write clean, testable code and know how to leave systems better than you found them.
You bring a product mindset — caring not just about what’s built, but why and how it delivers value to users.
