About the role

Company Overview
 
Focused Energy is the leading laser-driven fusion company, dedicated to creating clean, limitless fusion power. We unite top scientific and engineering talent to unlock commercially viable fusion energy using proven technologies. Our goal is to drive economic growth and scientific innovation through the adoption of clean, abundant fusion energy worldwide.
 
Your Role
 
As a Cryogenics Engineer (f/m/d), you will play a pivotal role in designing, modeling, and optimizing advanced cryogenic thermal and fluid systems for commercial-scale fusion energy solutions. You will collaborate with interdisciplinary teams to develop, simulate, and validate experimental designs, helping define the roadmap toward efficient and scalable clean energy.
 
What You’ll Do
 
Own the end-to-end simulation and analysis function for cryogenic thermal and fluid systems—from problem definition through model development, validation, and continuous improvement.

Lead analytical approaches for new and undefined challenges, applying first-principles research to create pioneering solutions.

Drive model validation through close collaboration with experimental engineers, comparing simulation outputs to test data, and closing performance gaps.

Ensure that the Cryo team’s hardware decisions are consistently supported by robust quantitative analysis.

Develop integrated thermal and fluid analysis packages for commercial-scale system development, conducting optimization and sensitivity studies as needed.

Continuously refine analysis models as new experimental, materials, and system data become available.

Partner closely with hardware engineers, experimentalists, and scientists to define system requirements and deliver actionable analyses for design.

Provide the analytical foundation for the Cryo team’s technical roadmap, guiding what gets built, tested, and scaled.

 
Who You Are
 
3–5 years’ experience (or equivalent PhD research) in integrated thermal and fluid analysis involving cryogenic systems (experience with hydrogen is preferred).

MSc or PhD in Mechanical Engineering, Physics, Chemical Engineering, or a related discipline.

Strong foundation in heat transfer, thermodynamics, and fluid mechanics.

Proficient in thermal analysis software (e.g., Thermal Desktop, COMSOL) and able to anchor analyses to real hardware.

Familiarity with hydrogen systems, vacuum systems, cryogenic technologies, and phase change in solids, liquids, and gases.

Skilled with instrumentation, sensors, and control logic for temperature, pressure, and flow in cryogenic environments.

Hands-on experience with test rig construction, system debugging, and low-temperature measurements to support model validation is a plus.

Comfortable collaborating across disciplines, and able to coordinate effectively with multiple engineering and science teams.

 
If you are excited about advancing clean energy and eager to make impact on a groundbreaking technology, we encourage you to apply.
