About Polymarket

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 Senior Full-Stack Engineer to own and scale the systems that power how Polymarket operates. You’ll embed with teams across the company, deeply understand their workflows and strategic goals, and lead the technical direction of the operational systems that accelerate them.

These systems center on Mission Control: the platform Polymarket uses to run Polymarket. Mission Control is the backbone for teams across the company, including Markets, Product, Polymarket US, Trust & Safety, Compliance, Exchange Operations, and Customer Experience. It is critical to how we create, configure, and launch markets, and to how we operate safely and compliantly at scale.

This is a high-ownership, high-impact role for an experienced engineer who wants to shape architecture, set technical direction, and deliver measurable value at the business level.

What You'll Do

• Own and expand Mission Control. Build and evolve the systems used to run Polymarket – the engine that drives Polymarket's markets, content, and growth.
• Build markets automation. Design and implement pipelines that streamline how new markets are researched, structured, deployed, and managed at scale.
• Drive projects end-to-end. Take complex, ambiguous initiatives from problem definition through architecture, implementation, and production, with direct impact on how the business operates every day.
• Work across a broad set of systems. Mission Control represents the broad range of operational systems (APIs, dashboards, workflows) that support teams across the company and tie directly into the core product. You’ll make key decisions about how these systems evolve and integrate.
• Work across the stack. Develop both frontend and backend code, using modern frameworks to solve practical problems quickly and cleanly.
• Embed with and partner across teams. Work directly alongside Markets, Product, Polymarket US, Trust & Safety, Compliance, Operations, and CX to understand their workflows, turn their needs into technical priorities, and influence how they work.
• Write clean, maintainable code. Set standards for code quality, system design, and reliability. Lead design and code reviews, and champion best practices across the team.

What We're Looking For

• 5+ years of professional software development experience
• Deep experience building full-stack web applications
• Strong skills in TypeScript, JavaScript (ES6+), and CSS
• Experience with React and Node.js (Next.js is a bonus)
• Strong customer empathy: you're good at understanding what different teams actually need, not just what they ask for
• Strong system design skills and a track record of making sound architectural decisions in fast-moving environments
• Proven ability to lead technical projects end-to-end and drive alignment across multiple stakeholders
• A bias for action: you're comfortable shipping quickly and iterating based on real feedback
• Comfort with ambiguity and context-switching: you can manage multiple systems and stakeholders without losing momentum
• Great communication and collaboration skills: you enjoy working across teams to solve real problems
• A passion for blockchain, decentralized finance, and freedom of speech
• (Plus) Experience in an embedded or field engineering role, working directly alongside product or operations teams
• (Plus) Experience with workflow automation or deployment pipelines
• (Plus) Background in fintech, crypto, or data-heavy applications
• (Plus) Bachelor's degree in Computer Science or equivalent
