Polymarket is looking for a backend engineer to help build and scale the core exchange infrastructure that powers our markets. This role is focused on high-performance, low-latency backend systems that must be correct, fast, and resilient under real-world trading load
You’ll be a core individual contributor working with other senior engineers to design, implement, and optimize the systems that sit at the heart of Polymarket’s exchange. This is a high-ownership role with minimal bureaucracy and a strong bias toward execution
We’re looking for an experienced backend engineer who enjoys working close to the metal and solving hard distributed systems problems
Build the exchange backend: Design and implement scalable, low-latency backend services that power Polymarket’s exchange, using C/C++ or other performance-oriented systems languages (Go, Rust, Java)
Optimize for performance & scale: Profile, tune, and debug systems with a focus on latency, throughput, memory usage, and correctness in production
Design distributed systems: Build and operate robust APIs, data pipelines, and event-driven systems using messaging and streaming platforms (Kafka, Pulsar, RabbitMQ)
Own reliability & operations: Reinforce security, availability, performance, and scalability across backend systems, and participate in diagnosing and resolving production issues
Collaborate cross-functionally: Work closely with engineers across product, infra, and data to ensure tight integration between the exchange and the broader platform
Contribute to code quality: Participate in code reviews, design discussions, and architectural decisions to maintain a high bar for engineering excellence
