About Densix
Densix is redefining what's possible in power conversion. Spun out of the University of Oxford and backed by leading 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 transitioning from breakthrough research to first product—and building a world-class engineering team to make it happen. If you're motivated by solving hard, real-world problems and want to see your designs move rapidly from concept to deployed systems, this is a rare opportunity to join at an early stage and shape both the technology and the company.
The Role
As a Power Electronics Engineer at Densix, you will play a central role in translating our core IP into robust, manufacturable products. This is a hands-on, multidisciplinary position suited to engineers who thrive in fast-paced environments —from architecture through to testing and customer deployment. You will work closely with a small, high-calibre team and have direct influence on technical decisions, product direction, and future IP development.
What You'll Do
- Design, build, test and validate cutting-edge power conversion systems
- Participate in major projects in electrical, mechanical, thermal, and manufacturing fields
- Take ownership of subsystems and contribute to overall system architecture
- Develop and execute rigorous test plans, including validation, reliability, and compliance (e.g. EMC, thermal, lifetime testing)
- Collaborate with customers and partners to integrate Densix technology into real-world applications
- Contribute to the generation and protection of intellectual property
- Stay at the forefront of developments in power electronics and related technologies
What We're Looking For
Essential
- MEng (or equivalent) in Electrical Engineering, Electronics, or a related discipline
- 2+ years of relevant industry experience
- Demonstrable track record in technical design, simulation, and experimental validation in analogue and digital electronic systems and circuits
- Proficiency at electronic design and PCB layout, including rapid prototyping and design iteration
- A proactive, problem-solving mindset with a willingness to take ownership and learn quickly
Desirable
- Direct practical experience of designing, building, and testing power electronic circuits and systems
- Experience of working on electrical systems operating above 600VDC
- Microcontroller software experience applicable to power electronics control systems (e.g., high speed feedback systems written in bare-metal C at >10kHz loop frequency)
- Mechanical design skills and related experience with mechanical CAD systems (Solidworks, Fusion360 etc.)
- Exposure to compliance and certification processes (EMC, safety standards)
Why Join Densix?
- Own meaningful work early – your contributions will directly shape our first products and future roadmap
- Cutting-edge technology – work with patented innovations pushing the limits of power density
- Small, focused team – collaborate closely with experienced engineers and founders
- Real-world impact – create products that enable more efficient power systems across global industries
- Growth opportunity – develop quickly as the company scales
Compensation & Benefits
- Salary: £45,000 – £55,000 (depending on experience)
- Share options (meaningful equity participation)
- 25 days holiday + bank holidays
- Contributory pension scheme
- Opportunity for rapid progression in a scaling deep-tech company
Final Note
We're looking for engineers who are not just technically strong, but genuinely excited by building something new. If you enjoy working across disciplines, tackling ambiguity, and seeing your work deployed in the real world, we'd like to hear from you.
