• Demonstrated experience providing technical leadership in embedded firmware development, including architecture, design reviews, and mentoring.
• Experience developing firmware for Arm Cortex-M or similar embedded processor platforms.
• Experience developing low-level peripheral drivers (SPI, UART, DMA, ADC/DAC, timers).
• Strong understanding of electrical circuits, power management, and sensor interfacing.
• Excellent hardware/firmware debugging skills, including analog and digital electronics, using oscilloscopes, logic analyzers, and JTAG/SWD debuggers.
• Experience developing products within regulated design control or quality management system (QMS) environments.
• Experience with configuration management, issue tracking, and problem resolution processes.
• Excellent technical documentation and written and verbal communication skills.
• Experience with real-time operating systems (RTOS), such as Micrium, FreeRTOS, ThreadX, or equivalent.
• Experience developing firmware for battery-powered or ultra-low-power embedded systems.
• Experience reading schematics, datasheets, and hardware design documentation.
• Experience with collaborative software development workflows using Git-based version control systems.
• Experience developing automated unit, integration, or verification tests for embedded software.

Preferred Qualifications

• Experience developing implantable medical devices, neurostimulation systems, or Class II/III medical devices.
