Building the future of prediction markets

Strike is a Y Combinator–backed startup reimagining how the world prices uncertainty.

We’re building the first prediction market that lets businesses hedge against real-world outcomes — protecting against uncertainty in the same way they hedge currencies or commodities.

Backed by Y Combinator, Quadcode, Transpose Platform Management, Pioneer Fund, Goodwater Capital, and others.

• Develop and maintain products for both external users and internal teams (dashboards, admin panels, internal tools).
• Collaborate closely with backend engineers to design, define, and integrate APIs; occasionally contribute to backend application logic when needed.
• Proactively identify and resolve performance bottlenecks, bugs, and other issues across all frontend platforms.
• Work closely with designers and product teams, contributing strong design intuition and ensuring high-quality, polished UI/UX execution across web and mobile.

• Strong familiarity with AWS services relevant to frontend development.
• Strong design sense and experience collaborating with designers/UX teams to deliver visually polished and intuitive interfaces.
