Rockstar🎓
Top SchoolGraham Kaemmer is an engineering manager in New York with 11 years of experience building backend systems, leading product teams, and founding startups. He combines hands-on engineering—contributing to open-source authorization tooling like oso by implementing query timeouts, dynamic constant loading, and role support—with product leadership roles at Rippling and Maven Clinic. A Yale Computer Science graduate and repeat founder (PatientBank, Veil), he brings entrepreneurial instincts to product-focused engineering management. Comfortable shipping Rust and Ruby backend fixes as well as shaping product direction, he blends deep technical troubleshooting with cross-functional leadership. One less obvious strength: he has repeatedly moved between individual-contributor engineering and product leadership, making him adept at translating complex technical trade-offs into pragmatic product decisions.
