About H-55

As the technological spin-off of Solar Impulse, the first electric airplane to fly around the world, H55's mission is to make aviation clean, safe, and affordable.

The company's strengths and competencies lie in developing propulsion and energy storage solutions that are modular, lightweight, and certifiable.

Having integrated and flown 4 electric airplanes, the Swiss start-up has been selected by Pratt & Whitney Canada to provide the battery pack for its regional hybrid-electric flight demonstrator. This recent announcement is a further illustration of H55's position as a major enabler in the electric commuter market.

About the role in the frame of its product development (Energy Storage System), H55 is hiring an EMI/EMC Expert.

Specifically, you will be responsible to:

  • Develop and implement EMI/EMC test plans, procedures, and protocols for aerospace applications.
  • Conduct EMI/EMC testing (Anechoic Chamber, Spectrum Analyzer, probe measurement) to ensure compliance with industry standards and regulatory requirements (e.g., DO-160, MIL-STD-461, MIL-STD-464).
  • Analyze test results, troubleshoot EMI/EMC issues, and provide detailed reports. (Shielding, Filtering, Grounding, Bonding,...)
  • Collaborate with design and engineering teams to incorporate EMI/EMC mitigation techniques in product development.
  • Write design documentation: EMI/EMC analysis reports, compliance matrices, and test reports.
  • Maintain meticulous documentation throughout the entire process.
  • Manage all EMI/EMC data under your responsibility according to our DO-254 development methodologies and configuration management rules.
  • Stay updated on the latest EMI/EMC standards, regulations, and testing methodologies.

  • EMI/EMC standards (e.g., CISPR, FCC, IEC, DO-160, MIL-STD-461)
  • EMI/ESD/EFT protection and filtering techniques
  • Mixed analog/digital circuit design, power supply (DC/DC), and circuit simulation tools (e.g., Simetrix, Spice)
  • Proficiency in Schematics entry and circuit board layout (e.g., Altium Designer).
  • Experience with PCB IPC standards.
  • Aerospace/aviation process and standard knowledge is a plus (under EASA/FAA CS-23 or equivalent).
  • Notions in Thermal Engineering (cooling) and Mechanical Engineering (enclosure) is a plus.
  • Proficiency in Matlab and Altium use is a plus.
  • Experience in environmental testing (temperature, vibration, EMI/EMC, DO-160) and aviation development assurance standards (DO-254) is a plus.
  • Fast learner, rigorous, with analytic problem-solving capabilities and ability to properly document.
  • Well-organized, capacity to prioritize & pro-active (start-up mindset)
