Senior Firmware Test Engineer
Core
Architect and drive the validation strategy for deeply embedded firmware across new and existing access control products, bridging the gap between hardware design, firmware development, and cloud-based test automation.
Role type
Senior Firmware Test Automation Lead
Builds
Hardware-in-the-loop (HIL) automation frameworks and comprehensive test strategies for the "hardware-to-cloud" journey
Domain
Access control and office automation (embedded systems, electronics, cloud)
Deliverable
production ML models | product features | dashboards & analysis | research | client delivery | infrastructure | physical/clinical work
Required skills
Firmware development (C/C++), RTOS and interrupt handling, Python for test automation, Hardware-in-the-loop (HIL) testing, embedded systems debugging (oscilloscopes, logic analyzers), communication protocols (RS-485, UART, SPI, I2C, TCP/IP, BLE, NFC, UWB), DFT/DFM integration
Preferred skills
Master's degree in EE/CS/CE, experience in lead/principal capacity, ability to design testability into product architecture
Technologies
