Summary
🤩
Rockstar🎓
Top SchoolJake Teton-landis is a Principal Software Engineer with 15 years of experience building developer productivity, web infrastructure, and systems-level tooling at companies like Notion and Airbnb. He combines hands-on expertise across the full stack—from memcached drivers and complex client-side performance work to Kubernetes-based service orchestration and native macOS UIs—while coaching engineers and shaping engineering processes. An active open-source contributor, he’s helped maintain Notion’s official JavaScript SDK and built a QuickJS/Emscripten integration to safely run untrusted JS, reflecting deep interests in runtime behavior, error handling, and maintainable code style. Jake’s work often focuses on developer velocity and durable systems (he authored Notion’s engineering proposal process and training materials), and he enjoys the “nerd” side of solving low-level integration and performance puzzles. Based in the United States and grounded in a UC Berkeley CS background, he brings a pragmatic blend of design, systems thinking, and productivity-first engineering.
