Summary
Senior engineer building and scaling high-performance exchange infrastructure for prediction markets, including order matching, APIs (FIX/REST/WebSockets), and clearing systems. Requires 5+ years experience in low-latency systems and strong proficiency in performant languages.
About the role
What you'll do
- Build and scale core exchange infrastructure - order matching, trade execution algorithms, and the data structures that underpin them
- Build APIs and data feeds that clients depend on - REST, FIX, WebSockets - and make them fast and reliable
- Design robust clearing infrastructure, position management, margining, and how money actually moves
- Drive technical relationships with our customers (market makers, traders, etc.)
- Hunt down performance bottlenecks - in databases, internal services, and anywhere latency is costing us
- Put systems under pressure before production does - rigorous testing of the things that can't go down
- Help invent what prediction market structure looks like beyond what exists today - new contract types, new mechanics, etc.
- Move fast, make calls, and own the outcome - we give real autonomy, which means real accountability.
What you bring
- At least 5+ years of engineering experience, with a track record on high-performance, low-latency systems
- Strong command of highly performant programming languages (C, Rust, C++, Go, Java, or similar) and the willingness and desire to flex into others
- You are product minded and scope well, you make good tradeoffs, and don't need hand-holding
- Demonstrable experience thriving in fast-paced and ambiguous environments, where high-agency and ambition go hand-in-hand
- Experience in TradeFi, prediction markets, crypto exchange infrastructure or SOR
Bonus points if you have…
- Background in sports, fantasy, or gaming
- Proven experience building highly available, high-volume consumer-facing systems
- Deep understanding of concurrency, threading models, and the tradeoffs in performance-sensitive systems
What we can offer you
- Unlimited PTO for full-time employees (we're extremely flexible with the exception of the first few weeks before & into the NFL season)
- 16 weeks of fully paid parental leave
- Home office stipend
- A connected virtual-first culture with a highly engaged distributed workforce
