Job Title: Electronics/Embedded Engineer II-III
Location: Cambridge
Type: Full-Time (on-site)
Coherence Neuro is a fast-growing, venture-backed company pioneering implantable technologies that interface with the human body to address critical unmet medical needs. We're looking for driven individuals who are passionate about pushing the boundaries of engineering and science to solve some of the most complex biological challenges. In this early-stage environment, we seek versatile team members with a hands-on approach and a willingness to learn quickly and adapt. We value diversity and encourage applicants from all backgrounds to join us in our mission. Learn about our team here!
We are building a robust translational research pipeline and looking for a detail-orientated and ambitious Electronics/embedded engineer II-III who is excited to contribute to the research and development of novel medical devices targeting the nervous system.
The successful candidate will work closely with our engineering research team to deliver hardware for preclinical research and should be comfortable in a fast-paced start-up environment where requirements and designs evolve rapidly. We are seeking someone with prior experience prototyping, implementing embedded firmware and electronics design.
Key Responsibilities
Design and implement embedded firmware on low power MCU systems for research implant-system interfaces, including precision timing control, power management, and interface communication.
Develop firmware and hardware validation test plans, and run board-level characterisation using oscilloscopes, function generators, impedance analysers, and specialised neurotech instrumentation.
Design and implement implant–system interface boards, including micro-connectors, flex PCB adapters, custom headstages, breakouts, adapter boards, and tethered/wireless interposers.
Design and test PCB assemblies for neural stimulation, including programmable drivers, charge-balancing circuits, compliance voltage management, and stimulation-safe protection networks
Prototype, assemble, and bring up multi-layer PCBs, perform schematic capture, layout review, component selection, soldering/rework, and hardware verification.
Support mechanical prototype development using rapid-prototyping methods (3D printing, laser cutting, basic machining), working collaboratively with surgical collaborators on implant form factors and fixtures.
Work with external fabrication partners, PCB manufacturers, and component suppliers.
Conduct root-cause analysis of device failures (electrical, mechanical, packaging, or interface-related) and implement design improvements.
Contribute to cross-functional projects alongside data scientists, preclinical researchers, and other engineers.
Required Qualifications and Skills
Bachelor’s, Master’s, or PhD in Electronic Engineering, Mechatronic Engineering, Mechanical Engineering, Biomedical Engineering, or equivalent.
2+ years of experience designing and developing embedded firmware and analog/digital electronic circuits, ideally for low-noise, low-power, or miniaturised systems.
Experience with C/C++ or similar.
Experience with embedded firmware MCU development, including timing-critical and low-power design.
Familiarity with communication interfaces (SPI, I2C, UART, BLE, custom optical/RF).
Experience with ECAD tools (Altium, Cadence) and an understanding of PCB design constraints.
Experience with rapid mechanical design and prototyping using 3D printing, laser cutting, and machining.
Adaptability to fast-paced research with dynamic priorities.
Strong communication skills and ability to work collaboratively in a interdisciplinary environment.
Strong analytical, documentation, and problem-solving abilities.
Bonus Skills
Experience with RF communication and wireless power delivery systems.
Direct experience with neural recording or stimulation hardware in animal or clinical applications.
Familiarity with neural recording/stimulating systems, stimulation hardware, or custom current/voltage driver circuitry.
Understanding of packaging, low-noise electronics, or flexible PCB design.
Experience designing devices for rodent or large-animal testing environments.
Reporting Structure:
This role is an integral part of the Research Engineering team and reports directly to the Lead R&D Engineer.
Benefits:
Competitive salary and share options.
Daily meals provided.
Professional development support and training opportunities.
Flexible working hours and travel opportunities (We have sites in Australia, UK and US!).
A chance to work on impactful, life-changing technologies in a dynamic, innovative environment.
