About the role
The exchange is the core of what Polymarket does. Every trade, every order, every market resolution runs through the systems this team owns. As a Senior Backend Engineer on the Services team, you'll be working directly on that infrastructure, building and scaling the backend that processes real money, in real time, at meaningful volume. The work is technical, high-stakes, and unambiguous in its consequences.
What they're looking for
- 4 to 7+ years of professional backend development experience, with strong proficiency in Go, Python, or Java. Go experience is a significant advantage
- Deep understanding of algorithms, data structures, concurrency, and memory management, with a track record of applying that knowledge to real production systems
- Experience building and debugging high-throughput, low-latency systems on Linux end-to-end, from design through to production operation
- Strong instincts for correctness, especially in systems where failures have financial consequences. You write defensively, think about edge cases early, and treat bugs in prod as a serious matter
- Comfortable working independently in a high-autonomy environment. You identify what needs to be done and do it without waiting to be unblocked
- (Plus) Experience in trading systems, high-frequency trading, gaming, telecom, or any domain where latency is a hard constraint, not a stretch goal
