This role is ideal for a seasoned backend or infrastructure engineer with a mastery of **Lua** and a deep understanding of networking internals. You should have at least 5 years of experience and feel at home working on high-traffic systems that handle billions of requests. If you enjoy optimizing web latency, managing TLS termination, and building global-scale CDN features, this is a top-tier opportunity. The compensation is highly competitive, ranging from **$196k to $280k**, plus equity and a dedicated WFH budget. As a fully remote position (US-based), it offers significant flexibility while placing you at the center of the modern web ecosystem. You’ll be working on high-impact projects—like global routing and request collapsing—that directly affect millions of developers. **You might be a good fit if you:** * Have extensive experience with **Lua** and ideally some familiarity with **Go**. * Understand the nuances of HTTP, web servers, and tail latency optimization. * Are excited to solve complex problems involving petabytes of data and edge computing. * Prefer a "just ship things" culture that balances experimentation with system reliability.
