IoT-embedded security platform for smart locks and access control
Bitkey builds embedded security hardware and cloud services around physical access control, with a tech stack spanning low-level embedded systems (C, C++, Embedded Linux, RTOS, Bluetooth Low Energy) and modern cloud infrastructure (Node.js, React, Firebase, Google Cloud). Active development across smart lock hardware, facial recognition services, and IoT devices for real estate signals a shift toward multi-modal authentication. Engineering dominates headcount (34 of 55 roles) with a mid-to-manager seniority skew, while noted pain points around vendor QA, AlloyDB migration, and IoT implementation at scale suggest the company is maturing infrastructure as product scope expands.
