Staff Software Engineer, Mission Control

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 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.

What We’re Looking For

8+ years of professional software development experience, including significant time as a technical lead or architect on production systems

Deep expertise designing, building, and scaling full-stack web applications and platforms

Expert-level skills in TypeScript, JavaScript (ES6+), and CSS

Extensive experience with React and Node.js (Next.js is a bonus)

A track record of setting technical direction and delivering large, cross-team initiatives from strategy through execution

Exceptional system design skills, including designing platforms that other teams build on

Proven ability to influence without authority and drive alignment among engineering, product, and business leaders

Experience mentoring senior engineers and shaping engineering culture, standards, and hiring

Strong customer empathy: you understand what teams actually need, not just what they ask for

Strong judgment under ambiguity: you know when to move fast, when to invest for the long term, and how to explain the difference

Excellent written and verbal communication, including the ability to write clear technical strategy and present tradeoffs to executives

A passion for blockchain, decentralized finance, and freedom of speech

(Plus) Experience building internal platforms or tooling for compliance, AML, surveillance, risk, or trading operations

(Plus) Experience in a regulated environment such as an exchange, brokerage, or financial institution

(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, exchanges, or data-heavy applications

(Plus) Bachelor’s degree in Computer Science or equivalent
