Lead Software Engineer at Oculus
Seattle, Washington United States
Summary
🤩
RockstarPer Vognsen is a Lead Software Engineer based in Seattle with nine years of experience building robust systems and shipping production software at scale. Currently at Oculus, he blends hands-on systems programming with technical leadership, guiding teams through complex engineering challenges. His open-source work on a DIY computer project showcases deep expertise in compiler design and low-level tooling—implementing lexers, parsers, string interning, and type checking for a C-like language. That background signals a rare combination of practical systems-level craftsmanship and higher-level architectural thinking. Colleagues describe him as a pragmatic problem solver who thrives where hardware-near code meets product requirements.
