About Polymarket

Polymarket is the world’s largest prediction market, allowing you to stay informed and profit from your knowledge by trading on future events across various topics. Backed by General Catalyst and Founders Fund.

About the role

We're building a dedicated growth engineering function at the org level, and this role sits at the center of it. Your mandate is user growth: owning the new user experience from first touch to first trade, reducing friction in the acquisition funnel, and building the surfaces that turn curious visitors into active traders. This is not a siloed frontend or backend job — you will work across the entire stack and cut into whatever territory needs cutting into.

What they're looking for

  • 7+ years of fullstack engineering experience, with real depth on both the frontend and backend — not just familiarity with one side
  • Proven track record shipping user onboarding flows, KYC integrations, or acquisition funnel features, with measurable results you can speak to
  • Experience working across teams in a larger engineering org, navigating ownership boundaries and getting things done without top-down coordination
  • Strong product instincts — you can look at a funnel, identify what is broken, and propose a fix without waiting for a product manager to hand you a spec
  • Comfortable making technical tradeoffs at the system level, scoping across frontend, backend, and external services and choosing the right approach for the constraint
  • Clear communicator who can align engineers, product managers, and stakeholders on scope and priorities without creating unnecessary process
