POWER HARDWARE ENGINEER FOR AEROSPACE SECTOR

Ingeteam, a leading company specialized in electrical engineering and the development of electrical equipment, motors, generators, and frequency converters, is looking to hire a Power Hardware Engineer for the Aerospace Sector at its Zamudio facilities. Your mission will be to design and validate power hardware for electric propulsion and energy conversion systems. Specifically, for the development of the power stage associated with DC/AC inverters for electric machines and DC/DC converters, including the selection of semiconductors (Si/SiC/GaN), magnetics, associated sensing, thermal design, and EMC/EMI considerations from early stages. You will be integrated into the company's R&D area within a multidisciplinary group focused on aeronautical systems. Your main functions will be: -Analyze the state of the art in aeronautical power electronics (topologies, WBG semiconductors, drivers, magnetics, cooling), to subsequently and based on requirements lead the design of concept, schematics, component selection, manufacturing, validation, and final testing of: o DC/AC Inverters (2/3 levels, multiphase, etc.) for electric motors. o DC/DC Converters (isolated and non-isolated: LLC, PSFB, DAB, interleaved, etc.) for electrical distribution. -Analyze customer specifications, breaking down the specification and defining the requirements applicable to the power hardware design. Requirements management ensuring traceability against design, analysis, and verification tests. -Define and justify the power architecture (voltages/currents, isolation levels, protection and derating strategy), including loss/efficiency calculations and sizing of critical components. -Design schematics and participate in the power layout (high current paths, minimization of parasitic inductances, control of dv/dt and di/dt, isolation/creepage/clearance distances, barriers, shielding), considering manufacturing recommendations and EMC rules. -Select and size: o Semiconductors (MOSFET/IGBT/SiC/GaN), diodes, snubbers, clamp circuits. o Gate drivers (isolated/non-isolated), driver power supply, DESAT protection, soft shutdown, Miller clamp, etc. o Magnetics (inductors, transformers), DC-link capacitors (film/electrolytic), current/voltage sensors (Hall, shunt, fluxgate, Rogowski), contactors/precharge if applicable. -Design and coordinate the thermal system: loss estimation, dissipation design (heatsink, cold plate, thermal interfaces), cooling requirements (air/liquid), and support for thermal simulations with the corresponding team. -Define and execute (or coordinate) protection strategies: OCP/SCP, OVP, UVLO, OTP, driver failure, shoot-through, isolation, DC bus discharges, transient management, fault robustness. -Plan and execute the validation and verification of the power stage: functional tests, efficiency, thermal, SOA, transients, EMI/EMC characterization, and support for environmental testing (DO-160) when applicable. -Manage design changes and collaborate with other departments (control, firmware, mechanics, systems, quality, and certification) to agree on changes considering the impact on requirements and testing. -Procure critical components (lead-times, alternatives, obsolescence) and follow up on manufacturing/assembly until obtaining prototypes and functional units. -Draft technical documentation: internal specifications, design justifications (calculations/derating), test reports, and support for customer/certification audits.

Minimum requirements: -Degree in Higher Electronic / Industrial / Telecommunications Engineering or similar. -Minimum of 4 years of experience in power electronics design in the aeronautical, automotive, railway, or high-demand industrial sector. -Demonstrable experience in DC/DC converters and/or DC/AC inverters (three-phase), including sizing, component selection, and prototype commissioning. -Knowledge of: Power semiconductors (IGBT/MOSFET) and wide bandgap (SiC/GaN): selection criteria, switching, losses, gate driving, and ringing/EMI mitigation. EMI/EMC in power electronics: input/output filters, common/differential modes, shielding, layout strategies, and laboratory measurements (LISN, current probes, near-field, etc.). Power magnetics (design/selection) and critical passive components (DC-link, film caps, busbars, laminates). -Experience in design and simulation tools: o CAD: Altium / OrCAD (or equivalent) for schematics and PCB support. o Simulation: LTspice/PSIM/PLECS/Simplis (or equivalent) for topology and transient analysis. -English minimum C1. -Report writing and technical meetings with customers.

The following will be valued: -Knowledge of Thermal/EM tools (Ansys, Icepak, Q3D, Maxwell) and integrity tools (e.g., HyperLynx).

-Applicable regulation/process: o Valuable knowledge of DO-254 (if part of the hardware has certification implications) and/or experience in equivalent processes (ISO 26262, IEC 61508) following the V-cycle. o Experience or familiarity with DO-160 (environmental/EMC testing for avionics/embedded equipment). -Experience in requirements management and traceability tools (Polarion, DOORS), writing requirements, and creating internal specifications from customer requirements.

We offer:

• Joining an innovative leading organization in Power Electronics, contributing to the energy transition model, impacting triple sustainability (social, environmental, and economic).
• Flexible schedule and other work-life balance facilities.
• Remuneration consistent with the candidate's experience.
• Permanent contract.
• Integration into a young, dynamic, and technologically advanced team.
