Staff Backend Engineer

When the world's biggest stories break, whether that's an election night, a Fed decision or a championship game, people come to Polymarket to see what's likely to happen next. Millions of trades, price updates and market resolutions flow through our backend as events unfold, and every one of them has to be fast and correct. We're hiring Staff Backend Engineers to own and shape those systems as Polymarket grows into a global source of truth.

This is an individual contributor role with high autonomy and high ownership. You'll work alongside a small group of senior engineers who care deeply about correctness and performance. There's no heavy process here, no committees, no long approval chains. You'll find the most important problems, propose solutions, and ship them. Depending on your background, you might focus on our exchange and trading systems, the platform behind our consumer apps, the systems that protect our users and markets from fraud and abuse, or new products we're bringing to market.
