• Strong experience in a systems programming language such as Zig or C/C++
• Strong understanding of Internet technologies such as JavaScript/TypeScript and HTTP

Bonus Points

• Experience with the internals of JavaScript runtimes: JavaScriptCore, V8, or SpiderMonkey
• Understanding of UNIX systems, kernel, or TCP/UDP networking
• Understanding of how to build multi-tenant, large-scale distributed systems
• Are a maintainer or frequent contributor to open-source software
