Heather Mills
Software Engineer - Reality Labs at Meta
Las Vegas Metropolitan Area United States
Summary
👤
SeniorHeather Mills is a pragmatic systems architect and software engineer with nearly two decades of experience modernizing large-scale validation, diagnostics, and cloud services. Currently at Meta Reality Labs after leading cross-company initiatives at Microsoft, she has reimagined legacy OS validation into cloud-native, multi-tenant platforms that scaled to tens of thousands of devices and VMs while cutting costs and cycle times dramatically. Known for shifting fluidly between program management, hands-on debugging, and dev-architect roles, she blends deep technical rigor with people-first mentorship to grow diverse teams and drive measurable QoS improvements. Her work has enabled faster Azure and device feature delivery, rescued stalled projects with decisive pivots, and saved millions by automating triage and diagnostics. Less obvious: she systematically designs for minimal production impact—introducing lightly invasive debugging and “device chaperone” standards that let unmodified retail hardware be used safely in high-scale validation.
