Strong programming skills in TypeScript, JavaScript, Go, Rust, C++, or another systems-oriented language.
A solid understanding of HTTP, APIs, proxies, streaming connections, and common distributed-systems failure modes.

Ability to reason carefully about security boundaries, credential handling, concurrency, state management, and backward-compatible deployments.
Clear written and verbal communication skills, with the ability to coordinate investigations and solutions across team boundaries.
Applicants should provide a resume or CV describing relevant engineering and operational experience.
