Overview:

We are seeking a Design Physicist to perform simulations aimed at optimizing and assessing the impact of low-mode asymmetries on implosion performance for Inertia’s target designs. In the near term, this role focuses on designing novel laser–target coupling schemes optimized for Inertia’s unique laser architecture. You will work closely with Inertia’s laser team, integrated systems teams, and target fabrication teams to develop integrated designs that achieve relevant target gains and are compatible with the fusion power plant system.

Primary Responsibilities:

• Using VISRAD for low-mode symmetry and view-factor modeling to optimize laser beam configurations and hohlraum geometry.

• Running integrated radiation–hydrodynamics simulations to model the radiation drive symmetry and impact on implosion physics.

• Collaborating with expert teams at Inertia and on an Inertia-LLNL contract to model LPI and drive uniformity using LLNL simulation capabilities.

• Design and analyze experiments to benchmark the beam-target geometry and radiation drive uniformity.

Qualifications:

Required:

• PhD in Physics, Applied Physics, Nuclear Engineering, or related field.

• Experience with radiation–hydrodynamics codes or computational modeling of plasmas.

• Strong foundation in radiation transport, fluid dynamics, or plasma physics.

• Programming or scripting experience (Python, C++, or equivalent).

Preferred:

• Experience modeling low-mode asymmetries and drive uniformity using VISRAD or view-factor-based tools.

• Background in inertial confinement fusion or high-energy-density related physics.

• Strong teamwork and communication skills.

Salary & Benefits:

• The base salary range for this role is $150,000 - $275,000; The pay range provided is an estimated base range for this role. Exact compensation may vary based on skills, experience, and education.

• We offer market-competitive compensation and an excellent benefits program, including Medical, Dental, and Vision plans, company-paid holidays, matching 401k, and more!
