Rockstar🎓
Top SchoolPatrick Lang is a Principal Software Engineer with over a decade of experience building and leading cross-functional teams to deliver production-grade software from kernel and firmware up through cloud orchestration and consumer device UIs. He has deep expertise in Windows and Linux, having driven Kubernetes on Windows to production stability as SIG-Windows co-chair and contributed to widely used projects like AKS/ACS engine and HashiCorp Packer. At Sonos he led large-scale migrations (Perforce to GitHub) and revamped build and release systems to accelerate engineering velocity for 100+ developers. Patrick blends hands-on engineering—automation, CI/CD, and image/build tooling—with program-level leadership and a focus on operational reliability. Outside of software he applies the same maker mentality to audio gear, coffee roasting, and home-brewed beer, reflecting a practical tinkerer’s approach to problem solving. He is notable for bridging open-source collaboration and proprietary product work, especially around Windows containerization and automated infrastructure.
