About the Role
Polymarket is looking for a Staff iOS Engineer to help build our iOS product as we invest seriously in mobile. This is a high-ownership role for someone who understands what it takes to build a great trading or wagering experience on mobile – the performance requirements, the real-time data challenges, the UI patterns that make fast-moving information feel intuitive rather than overwhelming.
You'll work closely with product, design, and engineering leadership to deliver a high-quality iOS experience and help raise the bar across the mobile codebase. The right person has been in this world before: they know what a great trading or sportsbook app feels like from the inside, and they want to build something better.
What You'll Do
- Own the iOS product. Take end-to-end ownership of Polymarket's iOS experience, from technical architecture and performance to product quality and release discipline.
- Set the technical direction. Make and own architectural decisions for the iOS platform, ensuring the codebase is built to scale and maintained with rigor as the product grows.
- Build for real-time. Design and implement experiences that handle live market data, fast-moving prices, and real-time order state in a way that feels fast and reliable to users.
- Raise the engineering bar. Lead code reviews, establish strong iOS engineering standards, and help grow the capability of the broader mobile team.
- Partner across the company. Work closely with product, design, and backend teams to align on priorities, define APIs and data contracts, and ship high-quality experiences end-to-end.
- Contribute to mobile strategy. Help shape how Polymarket thinks about mobile as a platform, including architecture decisions that set up the team for scale.
What We're Looking For
- Significant iOS engineering experience, with a track record of shipping and owning high-quality iOS applications in production
- Deep experience building trading, financial, or sportsbook applications – you understand the product domain and the technical demands that come with it
- Strong knowledge of Swift and the iOS SDK, with solid instincts around performance, memory management, and real-time data handling
- Experience building apps that consume live data feeds and display fast-moving information reliably and smoothly
- A high bar for product quality: you care about how things feel, not just whether they work
- Comfortable operating with broad ownership in a fast-moving environment
- Strong cross-functional communication skills: you work well with product, design, and backend engineers
- (Plus) Familiarity with WebSockets, streaming APIs, or other real-time data infrastructure
- (Plus) Experience leading or mentoring iOS engineers
- (Plus) Background in a high-growth startup environment
Benefits
- Competitive salary & equity
- Unlimited PTO
- Full Health, Vision, & Dental coverage
- 401k match
- Hardware setup: new MacBook Pro, big display, & accessories
