About Polymarket

Polymarket is the world's largest prediction market platform. We enable individuals to express views on real-world events by trading on outcomes across politics, economics, sports, culture, and current affairs. Built as a peer-to-peer marketplace with no centralized “house,” Polymarket aggregates diverse opinions into transparent, market-based probabilities that reflect collective expectations about the future.

We’re growing fast: both in volume ($21B traded in 2025) and in adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media, powered by fast, reliable, and deeply technical market infrastructure.

About the role

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.

What you’ll do

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.
