Summary

Rockstar🎓
Top SchoolLloyd Hilaiel is a seasoned engineering leader with 17+ years building products and teams that ship at scale, currently serving as Head of Engineering in Denver. He combines deep systems and C/C++ roots with modern full‑stack experience—contributing production libraries for JSON parsing, Node.js memory and load tooling, and Mozilla services used by hundreds of millions of devices. Lloyd has been an early engineer at multiple startups that exited (including Ozlo → Facebook) and led cloud and identity efforts at Mozilla, balancing technical depth with cross‑organizational strategy and ethical considerations. He’s comfortable spanning devops, native extensions, front‑end UX and test automation, and has a track record of turning hard infrastructure problems into reliable products. Colleagues describe him as a pragmatic builder who hires well, ships often, and still writes elegant low‑level code. Outside of org leadership, his open source work—like a fast C JSON parser and native Node modules—reveals an ongoing appetite for performance and tooling improvements.
