Firmware / Embedded Software Engineer

Bioliberty is on a mission to give everyone the best chance at recovery from a mobility-limiting condition or injury so they can reclaim their independence. Founded in 2020, we've raised $7 million from a mix of public and private investors and launched our first product to the U.S. healthcare market in May 2025. We hold seven patents across our core technologies, Lifehub and Lifeglov — both of which are FDA-registered. We’re now entering an exciting new phase of growth and are looking for a talented Firmware Engineer (mid-level) to join our team.

In this role, you'll design, develop, and optimise firmware solutions for our embedded systems, playing a critical part in product innovation and performance. Your work will involve real-time interaction with hardware, as well as wireless and wired communication with companion mobile applications. This is a unique opportunity to develop technology that makes a real-world impact, helping improve patient outcomes and enabling clinicians to deliver more effective and engaging therapy.

The role is based at our headquarters in the National Robotarium in Edinburgh — a world-leading centre for robotics, AI, and autonomous systems. Due to the hands-on nature of the work with physical hardware and test equipment, regular time in the office is expected, though we offer flexibility for remote work depending on workload.

Key Responsibilities:

• Develop, test, and debug firmware for Embedded Systems
• Collaborate with hardware engineers to achieve optimal system performance.
• Work closely with software engineers to interface hardware with digital platforms
• Utilize ARM-specific tools (e.g., Keil, ARM GCC, or IAR) for firmware development.
• Analyse and enhance efficiency, stability and scalability of system resources
• Integrate and validate new product designs
• Conduct code reviews and maintain high-quality firmware standards.
• Document firmware architecture and testing procedures.

Requirements:

• Bachelor's degree in Electronic Engineering, Computer Science, or related field.
• 3+ years of experience in firmware development for embedded systems.
• Proficiency in bare metal C/C++ for ARM (or similar) architectures.
• Solid understanding of ARM Cortex-M series or similar microcontroller families.
• Familiarity with hardware communication protocols (e.g. SPI, I2C, UART).
• Familiarity with ADC/DAC, DMA, timers, and other MCU peripherals.
• Experience with debugging tools (e.g., JTAG, SWD).
• Experience with issue trackers and version control systems (e.g. Git, Jira).

Nice to Haves:

• Exposure to Real-Time Operating Systems (RTOS) such as FreeRTOS or Zephyr on ARM platforms.
• Experience in peripheral drivers and middleware libraries like HAL or CMSIS
• Experience with Nordic / Zephyr BLE stacks.
• Familiarity with BLE protocols and standards (e.g. GATT, GAP).
• Experience in developing automated testing frameworks for firmware validation.
• Knowledge of the specifications and limitations of sensors and actuators
• Backend software for testing / data gathering, e.g. C#/C++/python
• Awareness of requirements capture processes and techniques.
• Experience in medical device development, including medical device standards. E.g. 60601, or similar.

What we offer:

• A competitive salary and benefits, with opportunities for professional growth.
• Holidays: 32 days paid leave including public holidays.
• Pension contribution: 3% employer, 5% employee.
• Office located in the National Robotarium Edinburgh. Cycle to work scheme.
• Private medical insurance.
• Flexible options for working environment and hours.
• Opportunities to travel for work to conferences, suppliers, customers, events as required.
