Senior Power Electronics Engineer
About the job
- A Master of Science or PhD in Electrical Engineering, Power Electronics, or equivalent is required.
- At least five years of hands-on research and development experience on motor drives, BLDC/PMSM controllers, or high-power-density power electronics is required.
- Deep working mastery of MOSFET commutation design, including gate-driver selection, dead-time tuning, switching transitions, and loss budgets, is required.
- Proven ownership of at least one motor-controller PCBA shipped from prototype through production or pre-production qualification is required; experience on drone, robotics, eVTOL, or automotive platforms is preferred.
- Fluency in simulation using LTspice, PLECS, or Simulink and PCB design using Altium is required.
- Strong experience and intuition in EMI/EMC design and debugging is required.
- Hands-on lab-bench discipline, including personally debugging issues missed by simulation, is required.
- Comfort with rapid scale-up iteration and end-to-end ownership is required.
- Fluent English is required as the working language.
- Lead motor-controller and DC-DC topology across fixed-wing, multicopter, and hybrid UXV platforms, and translate mission constraints into power-chain specifications.
- Own analog switching design, including dead-time tuning, gate shaping, and switching-loss, EMI, and thermal trade-offs.
- Use analytical loss budgeting, transient SPICE simulation with LTspice, and system-level modeling in PLECS or Simulink.
- Design three-phase BLDC inverters with integrated current sensing, protection, and hardware interfaces aware of trapezoidal control and field-oriented control.
- Lead schematic design and PCB layout in Altium or KiCad, engineering thermal, parasitic, and EMC considerations into the first revision.
- Drive pre-compliance testing, filter design, and root-cause debugging under flight-representative loads.
- Take motor-controller PCBAs through revision discipline, design for manufacturing, and qualification, and close the loop on field returns.
- Execute bench characterization using power analyzers, oscilloscopes, thermal imaging, and double-pulse testing, and reconcile results against simulation.
- Partner with embedded and propulsion teams on field-oriented control tuning, current-sense calibration, and the hardware/firmware compensation boundary.
- Set design standards through design-decision records and reference designs, and mentor one or two junior engineers.
- French language ability is a nice-to-have, but is not required.
- Experience with GaN or SiC is desirable.
- Exposure to safety-critical design is desirable.
- Applied control theory implemented in hardware is desirable.
- Exposure to defense, aerospace, or UAS programs is desirable.
About the company
Harmattan AI builds vertically integrated autonomous defense systems for NATO and allied forces. Its products include layered air defence, coordinated ISR and strike UAVs, electronic-warfare tools, and command-and-control platforms, all powered by a software-defined autonomy stack. The systems are designed to operate together, with autonomous decision-making, sensor fusion, and mission execution through its C2 framework. The company differentiates itself through large-scale industrial manufacturing, secured Programs of Record with European and UK defense ministries, and a strategic partnership with Dassault Aviation to embed Harmattan’s controlled autonomy into combat-air systems such as Rafale F5 and UCAS. The goal is to provide trusted, scalable autonomous solutions for defense missions, expanding globally and embedding autonomy into partner platforms to strengthen allied capabilities.

Simplify's Take
What believers are saying
- July 2026 NAMIB testing linked a drone sensor to Rafale targeting in flight.
- June 2026 France ordered 5,000 Sonora ISR drones after a prior 1,000-unit tranche.
- September 2026 Series B raised $200 million at $1.4 billion, funding global expansion.
What critics are saying
- Defence procurement concentration in France and UK ties revenue to two ministries.
- Harmattan claims 10,000 drones monthly, but public production audits remain absent.
- A high-profile Rafale or NATO autonomy failure could freeze deployment and kill trust.
What makes Harmattan AI unique
- Dassault embeds Harmattan autonomy into Rafale F5 and UCAS programs.
- Harmattan ships ISR, strike, EW, and C2 systems from one software stack.
- France and UK Programs of Record validate procurement traction against European peers.
