Summary
👤
Senior🎓
Top SchoolAllison Kaptur is a Head of Engineering based in San Francisco with 14 years of experience building resilient systems and leading engineering teams at Pilot.com, after senior roles at Dropbox and the Recurse Center. A hands-on Pythonist by background, she has deep expertise in virtual machine and bytecode-level development—contributing to notable open-source projects like Hy and byterun where she improved exception handling and Python 3 compatibility. Her career blends production engineering (desktop sync and auto-update systems at Dropbox) with mentoring and curriculum-style facilitation for developers, reflecting strong technical leadership and coaching skills. With an academic foundation in astronomy and physics from Yale, she brings a data-driven, analytical approach to system design and a history of tackling low-level, correctness-focused problems that most engineering leaders don’t often own.
