Design Physicist – LPI and Low-Density Plasmas
$150k - $275k USD
Overview:
We are seeking a Design Physicist to study laser–plasma interaction (LPI) and laser propagation physics relevant to Inertial Fusion Energy (IFE). This role focuses on understanding laser absorption, speckle formation, parametric instabilities, and hot-electron generation in laser-generated plasmas, to improve coupling efficiency and predictive modeling of Inertia’s fusion targets. You will work closely with the systems modeling and laser science teams to reconcile the target design and laser architecture for manageable LPI.
Primary Responsibilities:
Studying speckle formation and beam smoothing in high-powered laser systems.
Using simulation tools, such as pF3D, to estimate laser propagation and instability growth for Inertia.
Collaborating with LLNL on an Inertia-LLNL contract to model LPI using LLNL simulation capabilities.
Designing and analyzing laser–plasma experiments to study energy coupling, instability mitigation, and cross-beam energy transfer, integrating insights into the laser system and target design.
Qualifications:
Required:
PhD in Physics, Applied Physics, Nuclear Engineering, or related field.
Strong foundation in plasma physics and computational modeling.
Background in laser–plasma interaction or inertial confinement fusion research.
Experience with simulation tools or programming (Python, C++, or equivalent).
Preferred:
Familiarity with Maxwell–Vlasov (MV), MVFP, and PIC codes.
Strong communication and teamwork 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!
