• Expert-level programming skills in C/C++, Rust, Go, or Python, with strong fundamentals in algorithms, data structures, and systems design
• Deep understanding of Linux systems, performance, and resource management
• Proven experience building and operating fault-tolerant distributed systems at scale
• Strong problem-solver who thrives in complex, ambiguous environments and takes a data-driven, scientific approach
• Comfortable working across the stack-from low-level systems to distributed architecture and APIs
• Highly self-driven and autonomous, with the ability to proactively identify and solve problems
• Excellent written communication and collaboration skills in a remote, async environment
• Thoughtful user of AI-assisted development tools to enhance productivity while maintaining high standards of quality.
