Summary
🤩
Rockstar🎓
Top SchoolMartin Probst is a Principal Engineer based in Munich with 13 years of experience leading large-scale, cross-organizational technical initiatives that align engineering strategy with business needs. He has a deep background in TypeScript and build/tooling ecosystems, having driven migrations at Google to TypeScript and contributed to high-profile open-source projects like TypeScript, Angular, Closure Compiler and Bazel toolchains. At Google he founded a Munich TypeScript infrastructure team and later coordinated cross-Google consolidation efforts, demonstrating both hands-on engineering and program-level leadership. His work spans front-end formatting and framework improvements to backend compilers, automation and security hardening—an unusual blend that surfaces in contributions from JS formatting in clang to HTML sanitization in Go. Martin cares about products and people as much as code, organizing teams around technical visions and improving developer experience through build and profiling tooling. Now at Personio he applies that full-stack infrastructure experience to drive scalable engineering outcomes.
