The Role

We’re looking for a Senior Power Electronics Hardware Engineer to join our Power Electronics team in Barcelona.

What You’ll Do

• Engineer solutions that are compact, lightweight, uncomplicated, and cost-effective.

• Collaborate closely with the Stark Future Engineering and sourcing teams for seamless integration.

• Ensure project milestones align with defined timelines and objectives.

• Oversee the maturity workflow, establishing validation cycles throughout the development process.

• Work with suppliers to incorporate cutting-edge technology components.

• Actively contribute to hardware architecture development and design.

• Assist in shaping the working methodology for the Power Electronics team.

What you will bring to Stark

• Mechatronics/Electronics or Electrical Engineering Degree (BS, MS preferred).

• Background in developing electric powertrains for vehicles.

• Strong leadership experience.

• Exceptional analytical and problem-solving skills.

• Proven ability to collaborate within multidisciplinary teams and work independently.

• Comfortable in an agile, fast-paced, and innovative environment.

• High standards for performance, quality, and cost efficiency.

• Excellent communication and interpersonal skills; proficiency in English is essential.

Why work with us?

• The chance to work on a product people are genuinely passionate about

• A fast-growing company with real momentum

• A creative, international team based in Barcelona

• Competitive salary and benefits package

• Direct access to riders, race teams, and the product — this is not a remote-from-the-product role

• Subsidized lunch in our in house restaurant

• Free access to our in-house gym (including weekends!)

• 30 days of paid vacation
