What you will do

• Design and deliver production embedded firmware in C and modern C++ for STM32-based controllers and multi-board scientific instruments.
• Lead hardware bring-up, subsystem integration, and performance optimization across motion, imaging, illumination, sensing, temperature control, and related instrument functions.
• Develop and troubleshoot real-time FreeRTOS and CMSIS-RTOS applications, including scheduling, synchronization, interrupts, DMA, memory management, and fault recovery.
• Implement peripheral drivers, host-device protocols, Ethernet/TCP services, bootloaders, flash programming, image verification, and persistent configuration.
• Build unit, integration, hardware-assisted, and hardware-in-the-loop tests while maintaining build and continuous-integration workflows.
• Lead design and code reviews, document interfaces and technical decisions, mentor engineers, and drive root-cause analysis of regressions and field issues.

Requirements
