• Understanding of market microstructure concepts such as MEV, block building, and execution quality
• Experience with trading systems or exchange infrastructure
• Experience with DeFi protocol engineering
• Experience with fintech backend systems, including payments, custody, or execution
• Experience with high-frequency or other low-latency systems
• Background in security engineering
• Fully remote role within the United States
• High-ownership environment with meaningful influence over technical decisions
• Fast execution and frequent iteration based on real-world feedback
• Focus on elegant, scalable solutions to complex technical problems
• Opportunity to shape a new product from its earliest stages
