## ABOUT POLYMARKET

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 core C/C++ engineer to help build and scale our exchange infrastructure. This is a low-latency, high-throughput systems role focused on the heart of Polymarket’s trading engine. You’ll work on performance-critical components that directly impact market quality, reliability, and speed.

- Optimize for speed & scale: Profile, tune, and debug performance-critical systems, with a relentless focus on latency, throughput, and determinism.
- Design robust systems: Develop efficient algorithms and data structures, and build scalable messaging and event-driven systems (e.g. Kafka or similar).
- Own reliability & correctness: Reinforce the security, availability, performance, and scalability of core exchange systems through careful design, testing, and operational rigor.
- Collaborate deeply: Work closely with engineers across product, infra, and data to ensure tight integration between the exchange and the rest of the platform.
- Contribute to engineering excellence: Participate in design reviews, code reviews, and architectural discussions to maintain a high bar for quality across the codebase.

## WHAT WE’RE LOOKING FOR

- 5+ years of professional C/C++ experience with deep knowledge of algorithms, data structures, and low-level performance optimization.
- Proven experience building or operating low-latency, high-throughput, scalable systems in production environments.
- Strong problem-solving skills, comfort working on complex systems end-to-end, and an entrepreneurial mindset.
- (Plus) Background in finance, trading systems, networking, or exchange infrastructure
- (Plus) Experience with multithreading, lock-free programming, and advanced optimization techniques
- (Plus) Familiarity with distributed messaging systems (Kafka or similar)

## BENEFITS

- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup — new MacBook Pro, big display, & accessories

## PAY TRANSPARENCY

Base salary range: $250,000 to $500,000 annually, plus equity and benefits.
