Polymarket jobs

Polymarket, the world's largest prediction market platform, is hiring a Senior Backend Engineer to join their DeFi Trading team and own core improvements to their exchange systems. You'll focus on evolving their CLOB (central limit orderbook) engine to handle faster, safer, and more concurrent operations as the platform scales, working across low-latency APIs, high-throughput data streams, and settlement-aware order state. Key responsibilities include profiling and optimizing the CLOB engine's critical path, reducing lock contention without breaking correctness, building observability and safety into systems handling settlement risk, optimizing Go runtime performance, and owning production incidents end-to-end. You need production experience building low-latency backend systems, strong concurrency debugging skills, fluency in Go and Rust, deep observability experience (pprof, metrics, traces), and knowledge of exchange systems interacting with EVM/blockchain settlement. Nice-to-haves include matching engine experience, EVM transaction lifecycle knowledge, Go runtime tuning, and familiarity with Redis, PostgreSQL, gRPC, and Kubernetes. The role sits at a high-growth company ($21B traded in 2025) offering competitive salary, equity, unlimited PTO, and full health coverage—this is a deep systems role where the work is immediately visible in production and the stakes are real.

Polymarket is hiring a Senior Backend Engineer to work on Gamma, the core backend system that processes every market creation, trade, and resolution on the world's largest prediction market platform. You'll architect and implement Go-based microservices handling high-throughput, low-latency operations at scale, define engineering standards across the backend, conduct code reviews to uphold quality, and collaborate cross-functionally while owning system reliability through on-call rotations. Required experience includes 5+ years of production Go, strong API and microservices architecture skills, deep SQL expertise with PostgreSQL or MySQL, event-driven architecture experience with systems like Kafka or Redpanda, and hands-on observability with Prometheus/Grafana/OpenTelemetry. The company is experiencing explosive growth ($21B traded in 2025) and positioning itself as a global source of truth in media through prediction markets. Notable pluses include 1+ years of Rust, familiarity with trading or financial systems, and Web3/EVM experience, though these aren't required. Compensation includes competitive salary, equity, unlimited PTO, full health coverage, and hardware setup.
