About H-55

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

The company’s strengths and competencies lie in developing propulsion and energy storage solutions which 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.

Your Role

As an Electronic Hardware Engineer, you will contribute to the design, development, and verification of Electronic Control Board Assemblies (ECBA), with a focus on Battery Modules for next-generation Energy Storage Systems (ESS).

Working within a multi-disciplinary team, you will operate under the EASA Part-21J Design Organization (DO) framework and adhere to the rigorous standards of safety-critical development (e.g., DO-254, DO-160, CS-23). This position is ideal for an engineer with a passion for innovation, precision, and compliance in high-reliability systems.

Key Responsibilities

Schematic & Layout Design:

• Design and simulate mixed-signal circuits (analog/digital, HV/LV, temperature, current sensing)

• Integrate input protections, EMI/ESD filters, and power supply blocks (e.g., DC/DC converters)

• Include digital communication protocols (CAN, RS485, RS232) and microcontrollers (MCU-based systems)

• Develop complete schematics and layout using Altium Designer or equivalent ECAD tools (DWG, GBR, SCH, PcB, PnP,...)

• Specialized within Analog is a plus

Documentation & Compliance:

• Produce detailed Design Descriptions, calculations (FMEA; MTBF), and analysis reports (ASR)

• Maintain traceability and version control of all engineering data per DO-254 guidelines

Testing & Integration:

• Author and execute Qualification Test Plans (QTP) and Verification Test Procedures (VTP)

• Perform debugging, de-risking, and integration of PCBs at the module and system level

• Support the development of test benches and define Acceptance Test Procedures (ATP)

• Conduct environmental and functional testing in accordance with RTCA/DO-160

Process Rigor:

• Ensure adherence to internal and regulatory processes for configuration management, safety, and documentation

• Maintain high-quality standards through structured peer reviews, checklists, and change control

Your Profile

Education & Experience

• Bachelor’s or Master’s degree in Electronics Engineering

• CFC or technical apprenticeship in electronics (strong asset)

• 3–5 years of experience in safety-critical hardware development (e.g., aerospace, automotive, industrial, or medical sectors)

Technical Skills

Expertise in:

• Mixed analog/digital circuit design and simulation (SPICE-based tools such as Simetrix)

• Power electronics (e.g., DC/DC converters), circuit protection, and filtering

• High-speed digital interfaces and communication protocols (CAN, RS485, etc.)

• Schematic capture and PCB layout (Altium Designer or similar tools)

Familiarity with:

• EMI/EMC principles and PCB layout best practices

• IPC standards for PCB design and manufacturability

• Thermal and mechanical considerations in hardware enclosures (asset)

• Environmental and qualification testing per DO-160

• Aerospace standards such as DO-254, CS-23, EASA/FAA certification frameworks

Tools: Altium, MATLAB, Simetrix, version control/configuration tools

Soft Skills

• Fast learner with a rigorous, structured, and detail-oriented mindset

• Strong documentation discipline and ability to work in a certification-driven environment

• Excellent analytical and problem-solving skills

• Capable of working independently while collaborating effectively within a multidisciplinary team

• Fluent in English (oral and written); French is a strong asset

Why Join H55 (as a Consultant)?

• Work on cutting-edge energy storage technologies at the core of tomorrow’s aircraft

• Bring your aerospace experience to a mission-driven, fast-paced environment

• Collaborate within a culture built on TRUST, TEAMWORK, COURAGE, and PERSEVERANCE

• Help shape the certification and engineering excellence of next-gen clean aviation systems
