• Implement rigorous and thorough monitoring and testing to meet the stringent security and performance requirements of a system safeguarding real Bitcoin
• Design and implement supporting tools and utilities, such as CLI clients, applications that support moving sBTC on or off the Stacks blockchain, and utilities for monitoring signer health, benchmarking, or debugging
• Collaborate with other teams on new product features across the Stacks blockchain, including applications that support moving sBTC on or off the Stacks blockchain and protocol integrations
• Work closely with internal teams and external partners, communicating design decisions and trade-offs clearly as sBTC integrates with new products and partner systems

Skills

• 5+ years of experience
• Strong, demonstrated engineering fundamentals, including scalability, architecture, refactoring, algorithms, and testing
• Experience building and operating security- or reliability-critical backend systems
• Strong written and verbal communication skills, with the ability to work effectively with both internal teams and external partners
• Expertise in Rust, which is the primary language of the sBTC codebase
