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 Staff Full-Stack Engineer to define the technical strategy and long-term architecture of the systems that power how Polymarket operates. You’ll partner with leaders across the company, understand their strategic goals at a deep level, and shape how our operational platform evolves to meet them. These systems center on Mission Control: the internal 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 role for an experienced technical leader who wants broad ownership, influence across the organization, and a direct hand in how Polymarket operates as it scales. WHAT YOU’LL DO - Own and lead Mission Control. Set the technical vision and roadmap for the platform used to run Polymarket, the engine behind our markets, operations, compliance, and growth. - Build Mission Control as a platform. Design the core abstractions, data models, and extension points that let teams across the company build on Mission Control safely and quickly, without a dedicated engineer for every workflow. - Architect markets automation at scale. Drive the design of systems that change how markets are researched, structured, deployed, and managed as volume grows. - Make high-stakes technical decisions. Lead architecture and design reviews, weigh tradeoffs across reliability, security, compliance, and speed, and make sure our systems meet the standards of a regulated exchange. - Influence beyond your team. Work with core product, infrastructure, and data teams to align on interfaces, shared services, and standards. Identify problems across the company before they become blockers. - Embed with and partner across teams. Work directly with leaders in Markets, Product, Polymarket US, Trust & Safety, Compliance, Operations, and CX to turn their strategic goals into technical priorities and shape how their teams work. - Multiply the team. Mentor senior and mid-level engineers, set the engineering culture and quality bar, and help shape hiring and team growth.
