Full job description

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.

Pay: £45,000.00-£55,000.00 per year

Benefits:

Company pension
Employee stock ownership plan

Ability to commute/relocate:

Oxford OX3 8SB: reliably commute or plan to relocate before starting work (required)

Education:

Master's (required)

Experience:

power electronics engineering: 2 years (required)

Work authorisation:

United Kingdom (required)

Work Location: In person
