Summary
👤
Senior🎓
Top SchoolMartin Treurnicht is a software engineering manager with 17 years in tech and over a decade of hands-on experience building startups from the ground up, currently leading Step’s Growth team and the company-wide Mobile Guild in Oakland. He blends deep backend expertise—shipping secure systems like credit reporting, Metro2 serializers, and real-time monitoring—with product-focused mobile and frontend work that helped steer Step’s adoption of React Native and TypeScript. As an engineering leader he mentors teams, runs mobile hiring, and shapes cross-functional partnerships with marketing and product while keeping a strong emphasis on reliability and security. His open-source contributions to the widely used Java JWT library show a practical focus on cryptographic correctness and test coverage, not just features. Comfortable toggling between architecture, code reviews, and hands-on fixes, he brings a rare mix of system-level thinking and gritty implementation experience. Outside work he’s a hardware and code tinkerer who still builds custom PCs and enjoys solving low-level security edge cases.
