About Densix
Densix is redefining whats 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 youre 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 Youll 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 and protection of intellectual property
Stay at the forefront of developments in power electronics and related technologies
