Job Description

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.

• Create and maintain schematics, PCB layouts, bills of materials, assembly drawings and technical documentation using Altium Designer or equivalent EDA tools.

• Define and apply PCB design rules for high-power and mixed-signal boards, including polygon pour strategies, thermal via placement, layer stack-up selection, controlled impedance routing and design-for-manufacturability considerations.

• Support the selection, evaluation and benchmarking of power semiconductors, gate drivers, passive components, magnetic components, connectors and other critical hardware elements.

• Define, plan and execute hardware testing and validation activities, including functional verification, electrical characterisation, thermal profiling, efficiency mapping, EMC pre-compliance checks and fault-injection testing.

• Set up laboratory test benches, design test fixtures and implement measurement procedures using oscilloscopes, power analysers, thermal cameras, network analysers and other relevant instrumentation.

• Perform design verification against system-level electrical, thermal and safety requirements; document results, identify deviations and propose corrective design actions.

• Contribute to the analysis and resolution of hardware failures and unexpected behaviours observed during integration, testing or field operation.

• Support simulation and modelling activities for power converter topologies, control loops, thermal networks and electromagnetic behaviour, using tools such as LTSPICE, PLECS, MATLAB/Simulink or equivalent.

• Collaborate with firmware and embedded systems teams to support hardware bring-up, peripheral configuration and hardware/software co-validation activities.

• Maintain clear and traceable technical documentation, including design rationale, test plans, test reports, assembly procedures and revision histories.

• 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.

• Experience using Confluence, Git or similar tools for technical documentation and version control in collaborative engineering environments.

This position can be based either at Nanotec Building, San Cristóbal de La Laguna (Tenerife).

We're looking for curious, creative, tenacious and collaborative people, eager to do things and unafraid to tackle challenges in order to contribute to improving the society in wich we live.
