Summary
👤
Senior🎓
Top SchoolJohn Penning is a Senior iOS Engineer based in Portland, Oregon, with over a decade of experience building mobile and embedded systems. Currently at AllTrails, he brings 13–15 years of software experience that spans consumer mobile apps (shopkick, moovel Group) and device-focused engineering (Alarm.com), giving him a rare blend of frontend app polish and low-level hardware insight. He holds both a B.S. and an M.Eng. from Cornell, and his background in systems and device engineering informs pragmatic architecture and performance-minded iOS design. Colleagues rely on him to bridge product needs and technical constraints, shipping user-facing features while keeping reliability and device integration top of mind. An appetite for complex systems work—rooted in early co-op and internship roles at Raytheon and MITRE—makes him equally comfortable debugging hardware interactions or evolving a large-scale app codebase.
