Senior Embedded Firmware Engineer

Today, our device development is largely handled by an external partner. You'll be our internal technical authority for it - working hand in hand with that partner to keep firmware reliable and compliant now, while building the pathway to bring that capability in-house over time.

It's hands-on, safety-critical work on a device people wear every day: C/C++ on STM32, FreeRTOS on ARM Cortex-M, low-power and battery-operated, talking to iOS and Android over BLE.

You'll:

• Own the firmware relationship with our external development partner - direction, reviews, quality, and the verification and release evidence that stands up to regulatory scrutiny
• Build the pathway to bring firmware capability in-house - deciding what to internalise and when, and growing the team to do it
• Stay hands-on and set the standard: production-quality firmware, reusable frameworks, coding practices and reviews across current and future products
• Own security - threat assessment, vulnerability management, and secure device updates
• Work shoulder to shoulder with hardware, software, quality and regulatory, keeping everything traceable and compliant with ISO 13485 and IEC 62304

• 5+ years delivering embedded firmware through the full product lifecycle, with a track record of robust releases and clean documentation
• Strong experience with FreeRTOS on ARM Cortex-M in safety-critical settings
• Real depth in low-power, battery-operated devices that communicate with mobile over BLE
• 3+ years in a regulated industry - medical device and IEC 62304 ideally
• The credibility to direct an external development partner today, and the appetite to build and lead an in-house capability tomorrow
• Fluency in C/C++, embedded architecture, modular design, and disciplined Git-based workflows
• A security mindset for embedded firmware (a genuine plus)
