Job Details

Join the largest private inertial fusion company in the world

Building on the massive breakthrough from The National Ignition Facility achieving gain, First Light is seeking exceptional scientists, engineers, and technicians.

Desired specialities include high energy density physics, experimental physics, pulsed-power devices, mechanical engineering and numerical methods in order to design and build the largest pulsed power machine in the world which will demonstrate ignition.

A full description of each available position and further details about how to apply can be found on the careers section of our website:

First Light Fusion Ltd is a lean, focused and agile corporation researching energy generation by inertial confinement fusion. The company was spun out from the University of Oxford in June 2011, and is now a rapidly growing 100 person size based near Oxford.


First Light

First Light Fusion is a company established in 2011 focused on researching energy generation by inertial confinement fusion. Building on the success of the National Ignition Facility, we are designing and building the largest pulsed power machine in the world to demonstrate an ignition experiment that will lead to a power plant.

Why work for us
We are a small company with a huge mission. The only important aspect for the team, and for everyone, is the contribution they can make. 

Bringing together a team of highly skilled people dedicated to one mission forms a fantastic environment and culture where every person contributes and learns from each other.

We are fast paced and the work is incredibly varied – no week is the same.

Training and development
We are keen on collaboration and publishing. Typically people attend several conferences a year and will attend technical skill courses and summers school as needed.

The team has expertise and mentoring in many disciplines ranging from data science, software engineering, theoretical physics, ultra-high-speed diagnostics to warehouse management.

We also have an extensive management training course.

Graduate schemes
Typically graduates join as a graduate scientist and will either rotate around the department or sit within a dedicated group. Training happens through a mentorship scheme, line management and on-the-job training. Within the first year you would be trained up to be able to lead and deliver projects in line with the core science plan.

What we are looking for

  •  Smart, independent thinkers with a great attitude and a genuine interest and drive to solve the fusion energy challenge.
  • Supportive team members who push us forward and make us better.
