Job Description

Do you have proven experience of embedded software engineering within a highly regulated industry (ideally within class III medical devices)? If so, we want to hear from you!

Amber Therapeutics are looking an experienced Embedded Software Engineer to join our dynamic team. This is a full-time hybrid role based at our custom-built facility in Harwell, Oxfordshire. Amber is a pioneering neuromodulation company dedicated to transforming the lives of patients through advanced medical technology. We specialize in the development of cutting-edge active implantable medical devices.

The Role

As a Senior or Principal Embedded Software Engineer, you will contribute at a senior level to the design, development, verification, and validation of Class III active implantable medical devices. Working alongside the System Architect, you'll provide technical leadership in embedded software and systems integration, ensuring compliance to regulatory standards. This role is vital in delivering safe, reliable, and high-quality implantable products, while driving continuous improvement across engineering processes within a regulated framework.

Key Responsibilities:

Design, develop, and verify embedded software and tools for Class III Active Implantable Medical Devices. Lead subsystem and component design, ensuring robust integration and compliance with IEC 62304. Produce and review software requirements, architecture, and detailed design documentation. Develop, qualify, and maintain manufacturing and test fixtures, including subcontractor tools. Apply electronic schematics to support software development, debugging, and verification. Champion software engineering best practices -- version control, code reviews, CI, and automation. Support risk management, audits, and continuous improvement in line with ISO 14971 and ISO 13485. Mentor junior engineers and promote high technical and quality standards. Deliver assigned work packages to meet technical, schedule, and quality goals. Collaborate with cross-functional teams and external partners to ensure system-level alignment. Identify and manage technical risks to maintain project delivery. Contribute to innovation, intellectual property, and process improvements in software and system integration.

Experience with Class III Active Implantable Medical Devices or other high-integrity safety-critical embedded systems. Ability to interpret and integrate software with electronic schematics and hardware interfaces. Hands-on experience with embedded hardware bring-up, board support packages, and low-level firmware drivers (I2C, SPI, UART, ADC/DAC, timers, PWM, GPIO). Proficiency in version control (Git), automated testing, and continuous integration pipelines. Proven ability to generate clear, compliant documentation suitable for regulatory submissions. Excellent understanding of software lifecycle processes and quality system compliance.

Desirable

Experience in telemetry, stimulation, or sensing systems for active implants. Understanding of cybersecurity principles applicable to medical software. Familiarity with cloud computing or containerisation (Docker, AWS, Azure) for test and data systems. Strong working knowledge of IEC 62304 (software lifecycle), ISO 13485 (QMS), and ISO 14971 (risk management).[HB1] Experience working with Notified Bodies, FDA, or MHRA on software-related submissions. Strong mentorship and technical leadership within cross-functional teams


The successful candidate will be a proactive self-starter with strong project management skills and the ability to thrive in a fast-paced, changeable environment. An excellent communicator who can work effectively across cross-functional teams, you will be a highly skilled problem-solver to tackle complex, multi-disciplinary challenges. If you're ready to make an impact through innovation and precision in medical technology, we'd love to hear from you.
