Power Electronics Engineer

ARQUIMEA we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors.

Our areas of activity are Aerospace Defense & Security Big Science Biotechnology and Fintech.

Main function and scope:

We are looking for Power Electronics Engineer with solid experience in power distribution systems PCB design and hardware validation to join our Power Electronics Engineering Team.

The successful candidate will contribute to the development and validation of advanced power electronics hardware for embedded and electromechanical systems operating in technically demanding environments.

The role spans the full development cycle from schematic design and PCB layout through to prototype bring-up hardware testing and system-level validation and involves close collaboration with firmware control mechanical and systems engineering teams.

This position is especially suited to an engineer who combines strong theoretical foundations in power electronics with a practical hands-on approach to design and validation. The candidate will participate in multidisciplinary R&D and product-oriented projects where hardware reliability electromagnetic compatibility thermal performance and design traceability are critical requirements.

The candidate is not expected to be a senior expert in every area. We are looking for someone with solid power electronics fundamentals good technical judgement and a strong motivation to design build test and improve real hardware systems.

We are looking for curious creative tenacious and collaborative people eager to build real things and unafraid to tackle hardware challenges in order to contribute to the advancement of highly demanding technology sectors.

The ideal candidate is someone who enjoys designing building and validating real hardware systems learning from test results diagnosing failures at the bench and working in close contact with multidisciplinary engineering teams. We value strong technical intuition attention to detail design ownership and a proactive attitude over very extensive prior experience.

Key responsibilities:

• Design and develop power electronics hardware for embedded systems including DC/DC converters inverters motor drives battery management circuits power distribution architectures and associated protection circuitry.

• Provide hardware feedback to systems control and mechanical teams based on integration constraints measured performance and real-world operating conditions.

• Participate in design reviews component selection reviews and validation milestone assessments within the project team.

Candidate requirements:

• Degree in Electrical Engineering Electronics Engineering Power Electronics Industrial Engineering Telecommunications Engineering or similar.

• Proven experience in power electronics design including DC/DC conversion power distribution inverter or motor drive topologies or battery management systems.

• Strong knowledge of power electronics fundamentals: converter topologies switching behaviour passive component selection thermal design losses analysis and protection strategies.

• Proficiency in PCB design using Altium Designer with demonstrated experience in high-power and/or mixed-signal board layout.

• Understanding of PCB design constraints for power electronics: current-carrying capacity thermal management signal integrity EMI mitigation and design-for-test.

• Practical experience in hardware testing and validation: ability to define test procedures set up laboratory environments operate electronic test equipment and document results rigorously.

• Familiarity with power electronics simulation tools (e.g. LTSPICE PLECS PSIM or equivalent) for circuit-level verification and control loop analysis.

• Ability to read and produce electrical schematics component datasheets and technical specifications.

• Ability to work with evolving requirements incomplete information and technical uncertainty while maintaining a structured and methodical engineering approach.

• Strong willingness to learn new technologies take ownership of hardware tasks and contribute across disciplinary boundaries.

• Good communication skills and ability to collaborate effectively with electronics firmware mechanical systems and testing teams.

• Strong communication skills in English both written and spoken.

• Willingness to relocate to the Canary Islands.

Any relevant experience related to the following is a plus:

• Experience with battery management system (BMS) design: cell monitoring state-of-charge estimation cell balancing protection circuits and communication interfaces (SMBus CAN I²C).

• Experience with gate driver design and selection for SiC or GaN power devices operating at high switching frequencies.

• Knowledge of motor drive architectures including three-phase inverters FOC/SVPWM control and associated power stage design.

• Experience with digital twin modelling co-simulation or hardware-in-the-loop validation of power electronic systems.

• Experience with industrial or embedded connectivity standards used in power systems (e.g. CAN EtherCAT 10BASE-T1S Modbus CANopen or similar).

• Knowledge of EMC design techniques pre-compliance testing methodologies and filtering strategies for power electronic hardware.

• Experience with thermal management solutions: heatsink selection forced-air cooling heat pipe integration and thermal interface materials.

• Familiarity with design and qualification standards for aerospace defence or industrial power electronics (e.g. MIL-STD-704 DO-160 IEC 60950 or equivalent).

• Experience with Python or MATLAB scripting for automated test data acquisition post-processing reporting or hardware characterisation.

• Background in applied research or early-stage product development with strong hardware uncertainty.
