• Strong backend experience with a statically compiled language (e.g., Rust, Go, C#, C++)
• Solid fundamentals in distributed systems, API design, data modeling, and asynchronous processing
• Ability to work in precision-focused, correctness-critical financial domains (e.g., double-entry ledgers, reconciliation)
• Ownership-driven mindset focused on outcomes and high-throughput delivery
• Strong critical thinking, including productive use of AI tools while maintaining control of correctness, security, and design quality
• Interest in crypto/stablecoins/future payments (Track 3 requires hands-on blockchain development experience)
