Embedded Systems Engineer (Firmware & Electronics)

Embedded Systems Engineer (Firmware & Electronics)
At the Rehabilitation Engineering Laboratory (RELab) of ETH Zurich, we are developing
ax|ReCover
, a modular smartphone-based rehabilitation platform that aims to turn everyday smartphones into intelligent therapy devices for people with upper-limb impairments following neurological or traumatic injuries. Our unique solution combines modular hardware, embedded electronics, physiological and biomechanical sensing, and mobile software to make rehabilitation more accessible, engaging and personalised. We are looking for a new team member who wants to develop products that directly improve people's lives.
Project background
In the context of an Innosuisse funded project, we are looking for an Embedded Systems Engineer with a strong electronics background to lead the development and improvement of the embedded sensing platform of ax|ReCover. The funding for this specific position is limited to 16 months, and linked to specific work packages within that Innosuisse project. Working closely with our research team, you will be responsible for the embedded firmware and electronics that power our modular rehabilitation system, with the objective of transforming research prototypes into a robust, manufacturable product. This is a highly hands-on role spanning embedded software, electronics, sensors, prototyping and product development, in the field of neurorehabilitation technologies.
Job description

Develop Bluetooth Low Energy (BLE) communication between ax|ReCover and the smartphone
Implement synchronised sensor acquisition and data streaming
Design and iterate electronic schematics and PCBs for new hardware revisions
Select electronic components and contribute to electronics architecture decisions
Bring up and validate custom PCBs
Develop low-level drivers for sensors and communication peripherals
Collaborate closely with the research team on electronics integration and prototype development
Use oscilloscopes, logic analysers, mustimeters and other laboratory equipment to diagnose hardware and firmware issues
Optimise power consumption, communication reliability and embedded system performance
Support electronics testing, validation and design verification
Help establish engineering processes and documentation for future regulatory development
Profile

Experience bringing up and debugging custom PCBs
Strong electronics experience, including reading and understanding electronic schematics, digital and basic analogue electronics, sensor integration, component selection, power management fundamentals, and hardware bring-up and validation
Comfort using oscilloscopes, logic analysers, multimeters and other laboratory equipment
Strong debugging and troubleshooting skills across both hardware and firmware
Experience integrating sensors into embedded systems
Willingness to work closely with a small, multidisciplinary research team, and a strong interest in digital health and neurorehabilitation
Independence and a get-things-done mentality, with a self-starter attitude and comfort developing and testing novel ideas
Excellent communication and interpersonal skills, with first-rate written and spoken English and solid German skills.
Nice to have:
Experience with Nordic nRF52/nRF54 or STM32 development, Zephyr RTOS or FreeRTOS, NFC or USB, low-power embedded design would be advantages
Experience with battery-powered medical or wearable devices
