Electrical Manufacturing Engineer jobs

About Densix

Densix is redefining what’s possible in power conversion.

Spun out of the University of Oxford and backed by leading deep-tech investors, we are commercialising patented, ultra-high power density converter technology. Our innovations unlock smaller, more efficient, and more flexible power systems across high-growth sectors including AI compute, electric vehicles, grid infrastructure, and renewable energy.

We are now transitioning from breakthrough research to first product—and building a world-class engineering team to make it happen.

Joining Densix at this stage means more than just a role: you will help define how a fundamentally new class of power electronics is manufactured at scale. If you’re motivated by solving hard, real-world problems and want to see your work move rapidly from concept to deployed systems, this is a rare opportunity to shape both the technology and the company from the ground up.

The Role

As Lead Manufacturing Engineer, you will take ownership of how our technology is built—developing scalable, high-precision manufacturing processes for a novel class of power converters.

You will operate at the intersection of design and production, working hands-on to translate advanced engineering concepts into robust, repeatable manufacturing systems.

Key responsibilities include:

• Manufacturing processes: Develop manufacturing processes for Densix’s next-generation power converter products, from prototype through to early production.
• Automation & Tooling: Design, build, test, and iterate robotic assembly systems including hardware, software, processes to enable precision, repeatability, and scalability.
• Production Readiness: Lead the transition from R&D prototypes to alpha and beta builds, establishing processes that meet quality, yield, and reliability targets.
• Supplier & Partner Management: Work closely with suppliers, contract manufacturers (e.g. PCB/PCBA, precision machining, materials) and the engineering team to ensure quality, cost, and delivery targets are met.
• Test & Validation: Define and manage product testing programmes including accelerated lifetime testing, environmental and EMC testing as well as managing relevant certification programmes.
• Cross-functional Engineering: Collaborate with electrical, mechanical, and thermal engineers to ensure designs are optimised for manufacturability (DfM/DfA).
• Customer Integration: Partner with customer engineering teams to validate and adapt products for specific applications and environments.
• Continuous Improvement: Establish best practices, documentation, and scalable processes as the foundation for future manufacturing growth, staying up-to-date with power electronic technology and associated manufacturing.

What We’re Looking For

We’re looking for someone who combines deep technical capability with a builder’s mindset—someone comfortable creating systems from first principles in a fast-moving environment.

Essential:

• Degree (BEng/MEng or equivalent) in engineering or a relevant technical discipline
• 5+ years’ experience in advanced manufacturing environments (e.g. power electronics, robotics, precision engineering, or high-reliability systems)
• Proven track record of developing and deploying manufacturing processes, equipment, or automation systems from concept to operation
• Hands-on experience with robotic systems, tooling, and/or custom automation
• Strong understanding of design for manufacture and assembly (DfM/DfA) principles
• Experience working with external suppliers and manufacturing partners (e.g. for PCB and PCBA, CNC parts).

· Proficiency in mechanical and electrical design, with a practical, hands-on approach and ability to prototype, iterate, and solve complex problems quickly

Desirable:

• Experience with precision or high-density electronics manufacturing, including tabletop or small-scale robotic assembly systems
• Experience with accelerated lifetime and reliability testing of electronic systems
• Experience with certification processes (e.g. EMC, safety compliance)
• Experience with advanced materials or processes (e.g. additive manufacturing, adhesives, thermal management solutions)

· Experience in IP protection.

What We Offer

• Salary: £55,000 – £70,000 (depending on experience)
• Equity: Meaningful share options—be part of the upside you help create
• 25 days holiday + bank holidays
• Contributory pension scheme
• A rare opportunity to join a recently funded deep-tech spin-out at a pivotal stage
• Significant scope for progression as the company scales

Why This Role is Different

Most manufacturing roles optimise existing processes. This one builds them from scratch.

You will be defining how a new category of power electronics is produced—working on first-of-a-kind technology, in a company where your decisions will directly shape the product, the factory, and the future of the business.
