Manufacturing Lead Engineer in City of London

Onsite | Oxford, UK

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.

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.

• 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.
• Cross-functional Engineering: Collaborate with electrical, mechanical, and thermal engineers to ensure designs are optimised for manufacturability (DfM/DfA). Partner with customer engineering teams to validate and adapt products for specific applications and environments.
• 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.

Qualifications:

• 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.
• 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 advanced materials or processes (e.g. additive manufacturing, adhesives, thermal management solutions).

Salary: £55,000 – £70,000 (depending on experience)

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. Most manufacturing roles optimise existing processes. 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.
