Senior Electrical Design Engineer

We are looking for a Senior Electrical Design Engineer with 5-15 years of experience to take ownership of our industrial AC power architecture as we scale from 1 megawatt to multi-megawatt synthetic fuel plants. You'll be joining a lean, high-ownership engineering team at one of Europe's most well-funded hardware startups, designing electrical systems that power modular direct air capture, electrolyzer, and reactor subsystems. We need someone who combines deep technical experience in power systems and functional safety with the creativity to challenge conventional engineering approaches because we're designing for lowest cost of methane production, not highest efficiency. This is a foundational hire to bring in-house expertise that prevents costly redesigns as we scale toward 50MW unit production.

What will you be doing?

• Own the full AC power system architecture — optimizing power conversion, distribution, and balance of plant for cost, manufacturability, and reliability at megawatt scale
• Produce and maintain power architecture schematics, protection strategies, cable sizing calculations, and panel designs that meet regulatory requirements
• Lead or contribute to safety system architecture including HAZOPs, HAZIDs, FMEAs, and functional safety standards (IEC 61508) — ensuring designs are safe for environments with hydrogen present
• Design electrical systems (3-phase, motors, pumps, heaters, I/Os) across the reactor, electrolyzer, and direct air capture subsystems, accounting for variable solar-powered production profiles
• Lead panel certification activities under the Machinery Directive and Low Voltage Directive (CE/UKCA) and mentor junior engineers
