Systems Engineer / Electrical Engineer – Battery & Power Electronics Integration

About Aerostrad

Aerostrad is a Swiss deep-tech startup based in Sion, Valais, incubated at The Ark Foundation. We build the infrastructure that lets airports cut ground emissions today, and charge electric aircraft tomorrow.

The Role

We are looking for a Systems Engineer / Electrical Engineer to own the technical integration between our battery-based power sources and the power electronics that deliver certified ground power to aircraft. You will define the requirements and system architecture that connect the battery, power controllers, and aircraft-side interface into one reliable, certifiable platform from a validated prototype into an industrialized product. This is a foundational engineering hire: you will work directly with our founding team and OEM partners, and your architecture decisions will shape every unit we deploy across Europe.

What You Will Do

• Lead the definition of system and subsystem requirements for battery-to-power-electronics integration, from concept through certification-ready design.
• Design the architecture linking battery packs, power controllers, converters, and protection logic, ensuring compatibility with aircraft-side electrical interfaces (voltage regulation, frequency matching, protection coordination).
• Own the interface between certified OEM hardware components and Aerostrad's integration layer, keeping the full system within aviation electrical safety standards.
• Translate field data into design improvements, closing the loop between operational performance and engineering decisions.
• Coordinate with OEM hardware partners on component selection, integration testing, and industrialization of our power unit.
• Document system architecture and requirements to support future certification, supplier audits, and team scale-up.

What You Bring

• A degree in electrical engineering, systems engineering, or a related field.
• Solid, hands-on experience in power electronics and/or battery system integration — ideally within electric mobility, aerospace, rail, or heavy electrical equipment.
• Working knowledge of requirements engineering and system architecture definition for safety-relevant electrical systems.
• Familiarity with power conversion, protection logic, and grid- or vehicle-side electrical interfacing (e.g. voltage regulation, frequency matching).
• Comfort working directly with hardware in a workshop environment, not just on paper — this role sits close to the physical unit.
• A pragmatic, ownership-driven mindset suited to a startup: you will be defining processes as much as following them.
• Professional fluency in English; French is a strong plus given our Valais base and airport partners.
• Eligibility to work in Switzerland (Swiss or EU/EFTA nationality, or existing valid Swiss work authorization).

What We Offer

• A founding-team-level role with real ownership over the architecture of a physical product deployed at a live airport.
• A flexible, balanced working culture — we care about output and impact, not hours logged. Flexible scheduling and a genuine respect for life outside work.
• A front-row seat as the company scales from 2 to 19+ FTE over the next five years, with room to grow into a technical leadership role.
