About the Role

We’re looking for a Hardware Electronics Engineer to take ownership of the electronics platform that powers our next-generation biosensor devices. Working closely with the founders and a multidisciplinary team across firmware, mechanical, optical and systems, you’ll translate product goals into robust architectures and executable development plans, taking designs from early concepts through prototypes, verification and release.

Responsibilities

  • Take technical ownership of the electronics architecture for our medical device, driving development from early concept through prototype, verification and product release.
  • Design mixed-signal electronic systems, integrating optical modules, battery management, power electronics, motor drivers, user interface electronics and supporting sensors.
  • Design schematic capture and multi-layer PCBs, selecting appropriate components and integrating commercial modules into robust product designs.
  • Develop and validate battery charging, power management and low-power system architectures for portable medical devices.
  • Design interfaces for miniature cameras, LEDs, pumps, motors and user interface hardware including buttons, indicators and status LEDs.
  • Bring up, debug and validate prototype hardware using laboratory test equipment, identifying root causes and implementing robust design improvements.
  • Work closely with firmware, mechanical, optical and systems engineers to ensure seamless hardware integration across the product.
  • Plan and scope electronics development activities, identifying technical risks, defining development priorities and estimating work required to achieve project milestones.
  • Own the electronics design documentation, including schematics, design calculations, test plans, verification reports and manufacturing documentation.
  • Lead electronics risk management activities, maintaining Design FMEAs and supporting system-level risk analysis throughout product development.
  • Work with PCB manufacturers, assembly houses and component suppliers to support prototype builds, design for manufacture (DFM) and design for test (DFT).
  • Identify and establish the laboratory equipment, software tools, suppliers and development processes required to build a world-class electronics function.
  • Contribute as a hands-on individual contributor while helping shape the future electronics capability as the team grows.

Requirements

  • Master's degree (or equivalent experience) in Electronic Engineering or a closely related discipline.
  • 3–5 years' industry experience developing electronic products from concept through prototype and into manufacture.
  • Strong experience designing mixed-signal electronic systems including analogue, digital and power electronics.
  • Experience with schematic capture and multi-layer PCB design using Altium Designer (or an equivalent ECAD package).
  • Experience selecting components, designing circuits and integrating commercially available modules into complete electronic systems.
  • Experience designing battery-powered embedded systems including battery charging, power regulation and power management.
  • Experience designing interfaces for motors, pumps, LEDs, cameras, sensors and other peripheral devices.
  • Strong hardware debugging skills using oscilloscopes, logic analysers, power analysers and other laboratory equipment.
  • Experience with PCB bring-up, fault finding and hardware verification.
  • Understanding of EMC/EMI, signal integrity and design for reliability.
  • Experience working with contract manufacturers and supporting PCB assembly and prototype builds.
  • Experience planning technical work, managing electronics risks and taking ownership of engineering deliverables.
  • Excellent communication skills and the ability to work effectively within a multidisciplinary engineering team.
  • A proactive mindset with a willingness to take ownership of challenging technical problems.
  • Experience developing electronics for medical devices or regulated products.
  • Experience with optical systems including cameras, LEDs, photodiodes or imaging hardware.
  • Experience designing motor driver circuits or fluidic/pump control systems.
  • Experience with USB, USB-C or battery charging ICs.
  • Familiarity with embedded firmware development and debugging.
  • Knowledge of Design FMEA, Risk Management and Design Verification within regulated product development.
  • Experience supporting Design for Manufacture (DFM), Design for Assembly (DFA) and Design for Test (DFT).
  • Familiarity with standards such as IEC 60601, IEC 62304 or ISO 14971.
  • Experience working closely with external PCB manufacturers, assembly partners and component suppliers.
  • Prior work in a start-up or small company environment.
