OrganOx is looking for a Senior Electronics Design Engineer to take a leading role in the design, development, and verification of electronic systems for our medical devices. You will combine hands-on electronics design with technical ownership of subsystems, supporting architectural decisions and mentoring less-experienced engineers.
What You'll Do
- Own the design and development of electronic subsystems from concept through to manufacturing handover.
- Design analogue, digital, and mixed-signal circuits with a strong focus on safety, reliability, and compliance.
- Produce and review schematics and PCB layouts.
- Support electronic architecture decisions in collaboration with the Principal Electronics Engineer, Software engineering and systems engineering.
- Perform component selection, design calculations, and risk assessments in line with IEC 60601 and ISO 14971.
- Lead electronics design verification activities, including functional testing, EMC pre-compliance, and safety-related testing.
- Support debugging and root-cause analysis during prototype development and verification.
- Prepare and maintain high-quality technical documentation suitable for regulated medical device development.
- Support transfer to manufacturing, including engagement with suppliers and CMOs.
- Provide technical guidance and informal mentoring to junior electronics engineers.
- Participate actively in design reviews and contribute to continuous product improvement.
What We're Looking For
- Proven experience taking electronics designs for safety-critical products from concept to manufacturing.
- Expertise in analogue, digital, and mixed-signal circuit design.
- Deep understanding of design for compliance within regulated industries, particularly medical devices.
- Strong proficiency with electronics design verification, including EMC and safety testing.
- Ability to produce and review schematics and PCB layouts.
- Excellent problem-solving skills for debugging and root-cause analysis.
- Experience creating and maintaining technical documentation for regulated development.
- Strong collaboration skills to work with cross-functional teams and mentor junior engineers.
