Hardware Engineer

Your responsibilities
Development

• Own the electronics architecture of the device: processor platform, power supply, sensing, actuation, display, connectivity.
• Circuit design and PCB layout, from concept through to release
• Analogue measurement chains for pressure, temperature and flow sensing — low noise, low drift, calibratable.
• Drive electronics for pumps, valves, heating and cooling elements, including the power stages.
• Build, bring-up and characterisation of prototypes.
• Safety and evidence.
• Electrical safety concept under IEC 60601-1: insulation coordination, creepage and clearance distances, protective earth, single-fault safety.
• EMC-compliant design under IEC 60601-1-2, pre-compliance measurements and support through certification testing.
• Design of an independent hardware protection layer: watchdog, interlocks, pressure and temperature limiting.
• Contribute to risk management under ISO 14971; derive and verify hardware risk control measures.

• Design verification: test planning, execution and documentation as part of the technical file

   

Production readiness

• Design for reprocessing: connectors, sealing concepts and resistance to cleaning and disinfecting agents across the specified service life.
• Design for manufacturing and test: test strategy, production programming, test fixtures.
• Component qualification, second sources, long-term availability and obsolescence management.
• Work with EMS providers, prototype builds and production ramp-up
   

Collaboration

• Work closely with embedded software: platform decisions are made together, not one after the other.
• Interface with mechanical engineering, systems engineering, regulatory affairs and manufacturin.

Required

• Several years in electronics development for complex embedded devices, from schematic to finished layout (7+ as a guide).
• IEC 60601-1 or an equivalent product safety standard (e.g. IEC 61010) — insulation concepts, creepage and clearance, single fault analysis are routine for you, not new ground.
• Solid practice in analogue measurement: sensor front-ends, ADC interfacing, noise, offset and drift, calibration concepts.
• EMC-compliant design in practice — including the experience of analysing and fixing a failed EMC test.
• Confident with a professional EDA tool (Altium, KiCad, Cadence or comparable).
• Lab measurement skills: oscilloscope, spectrum analyser, network analyser, thermography
• Fluent German and English
   

Nice to have

• Medical devices and the associated documentation (design history file, design verification).
• Further parts of the 60601 series, in particular -1-2 (EMC), -1-6 (usability) and -1-8 (alarm systems)
• Mains-side power electronics, switch-mode supplies, isolation barriers, motor drive.
• Signal and power integrity on fast interfaces (DDR, LVDS, Ethernet).
• Modern 32-bit microcontroller platforms and the circuitry around them.
• Thermal design and simulation.
• Experience setting technical direction across distributed or partner teams.

What we explicitly do not require

• Prior experience in our application field. We will teach you the domain.
• Every line of the list above. If three quarters fit and you want to learn the rest, apply.
