Power Electronics Engineer
Embedded Power & Control Electronics 📍 Location: Paris Region (on-site) 🛰️ Sector: Next-gen European Defense 💼 Type: Full-time, Permanent 📈 Seniority: Senior 💰 Compensation: Competitive Salary + Equity + Full Health Coverage About EGIDE EGIDE is building a new European defense leader focused on scalable, intelligent air-defense architectures. We develop mass-use interceptors designed to neutralize low-cost, high-volume threats such as Shahed-type loitering munitions and FPV drones. Our systems combine missile-grade lethality with modern software-defined architectures and electrically propelled interceptors, enabling a new class of cost-effective and rapidly deployable air defense solutions. We are assembling a world-class engineering team to design, test, and industrialize these systems at pace. About the Role As a Power Electronics Engineer, you will lead, directly or through design subcontractors under your technical authority, the design and industrialization of the embedded power and control electronics of our airborne and ground systems. You will own both the power stage and its control: power conversion and distribution, three-phase inverters and motor control for high-speed electric machines, energy storage and power switching circuits, and system power supplies. The scope ranges from a few watts to tens of kilowatts, over a 3V to 60V voltage range and from milliamps to the hundred-amp range, under severe mass, volume, thermal and environmental constraints. You will cover the design lifecycle from specification to a validated, production-ready definition, integrating manufacturability, assembly and testability (DFM / DFA / DFT) and cost from the first schematic. Industrialization and production are carried out with the support of internal or external manufacturing engineers and EMS partners, with whom you will work closely, as well as with the Munition Safety Engineer and the electronics, embedded software, propulsion and mechanical teams. What You’ll Do Define power architectures and specify power boards from system requirements: power budgets, voltage rails, protection strategy, energy management, thermal and mass allocations.

Design for manufacturing, assembly and test (DFM / DFA / DFT) with a design-to-cost approach: component standardization, automated assembly compatibility, thermal interface and potting constraints, test access and production test requirements
Support the manufacturing engineers and EMS partners during industrialization: design data package, prototype and pre-series builds, technical support on non-conformances and design changes
Produce and maintain the definition package (specifications, design justification, ICDs, test and acceptance procedures); participate in design reviews (PDR, CDR, PRR)

Lab expertise: power stage bring-up, double pulse testing, power analyzers, differential and current probes, thermal imaging
Understanding of EMI / EMC constraints of switching converters (input filters, layout,
conducted and radiated emissions)
Working knowledge of DFM / DFA / DFT constraints for power assemblies and a design-to-cost mindset
Ability to write structured engineering documentation and to work across multidisciplinary interfaces
Nice to Have Experience in electric vehicles, ground or airborne (e-mobility, eVTOL, drones): traction inverters, power distribution, onboard converters
