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 terms of volume ($21B traded in 2025) and adoption as an alternative news source. Our ambition is to become a ubiquitous beacon of truth in global media and we need your help adding fuel to the fire.
About the Role
Polymarket is looking for a pragmatic full-stack engineer to join our US Exchange team. You'll build the critical internal systems that power our CFTC-regulated exchange operations—from payment reconciliation and transaction processing to operational dashboards and compliance tooling.
This is a high-impact role where you'll work directly with operations teams, build systems that handle real money at scale, and help establish the technical foundation for our growing US exchange business. If you enjoy solving complex problems in fintech, building tools that people actually use every day, and shipping code that matters, this role is for you.
What You’ll Do
- Build tools for US exchange operations. Create systems that help control desk operators, supervisors, and compliance teams manage high-volume payment processing and reconciliation workflows.
- Ship production features regularly. Launch improvements and fixes frequently in a fast-paced, regulated environment where reliability matters.
- Work across the full stack. Build frontend interfaces for operational dashboards and backend APIs for transaction processing, reconciliation, and payment provider integrations and other control desk operations.
- Collaborate with internal teams. Partner closely with operations, compliance, and product to understand workflows, gather feedback, and iterate quickly on tooling.
- Design for scale and compliance. Build systems that handle thousands of daily transactions while maintaining audit trails and meeting CFTC regulatory requirements.
- Contribute to technical decisions. Participate in architecture discussions, code reviews, and help establish best practices for the team.
What We’re Looking For
- 3-7 years of professional software development experience
- Strong full-stack web development skills with TypeScript. Strong backend experience with Go.
- Solid experience with React and Node.js (Next.js experience is a plus)
- Experience building data-heavy applications or internal tools
- Ability to work with external APIs and integrate third-party services
- Strong collaboration and communication skills—you work well with non-technical stakeholders
- Bias for action—comfortable shipping iteratively and refining based on user feedback
- Builder's mindset—you take pride in creating tools that solve real operational problems
- (Plus) Experience with MongoDB
- (Plus) Background in fintech, payments, reconciliation systems, or regulated environments
- (Plus) Familiarity with customer service or operations tooling
- (Plus) Understanding of financial data modeling and audit requirements
- (Plus) Bachelor's degree in Computer Science or equivalent
Benefits
- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup — new MacBook Pro, big display, & accessories
