Polymarket is looking for a senior/staff backend engineer to own the systems that connect our exchange to the outside world — market data distribution, order routing, and the high-throughput event pipelines that keep trading fast and reliable at scale
This is a high-ownership individual contributor role with direct impact on the reliability and latency of Polymarket’s core trading infrastructure, working alongside senior engineers with minimal bureaucracy and a strong bias toward execution
Build high-throughput connectivity infrastructure: Design and scale distributed, event-driven systems (Kafka, gRPC, DynamoDB/Redis) that process hundreds of millions of events per day
Own latency and scale: Profile and optimize order routing, market data distribution, and protocol-level integrations, driving 10x+ improvements in latency and throughput as volume grows
Drive operational excellence: Run production on-call, lead KTLO and reliability initiatives, and standardize logging, deploy, and incident-response practices across the team
Work close to the exchange: Partner on order routing, rate limiting, and protocol-level integrations that connect Polymarket’s exchange to market participants and downstream systems
Provide technical leadership: Mentor engineers, contribute to hiring, and help set technical direction while remaining hands-on with delivery
Collaborate cross-functionally: Work closely with Core Exchange, Markets, and Infra teams to keep connectivity systems tightly integrated with the rest of the platform
