Overview We are seeking Opto/Mechanical Engineers to advance high power laser system design and testing capabilities for Inertia’s fusion energy program. A key element is developing the world’s highest average power pulsed lasers, which will form the ‘unit cell’ of our power plant. In partnership with industry, government and academia, we will build a demonstrator beamline to deliver 10 kJ at 10 Hz with 10% wall-plug efficiency using diode-pumped solid-state laser technology (DPSSL). These positions initially involve developing test stands for the various system elements, including optical and thermal tests of the amplifier, testing pulsed semiconductor laser diode arrays, testing high damage threshold optics, and developing manufacturing methods for a wide range of optical components.

Primary Responsibilities

Design state-of-the-art, robust, high-stability optomechanical systems for high average power, high-energy laser systems.

Perform opto-mechanical analysis to optimize pointing stability, thermal drift, and mounting stress.

Conduct heat flow, stress, and birefringence analyses using FEA and CFD tools such as COMSOL/Abaqus.

Create engineering drawings using SolidWorks to develop and procure optics, mechanics, and support items.

Develop test plans to evaluate designs.

Collaborate with optical and systems engineering teams to deliver integrated designs.

Qualifications

BS or MS in Mechanical Engineering, Optical Engineering, or a related field.

Direct design experience with precision opto-mechanical products.

Strong CAD and design-for-manufacturing skills.

Hands‑on experimental and prototyping experience.

Salary & Benefits We offer market‑competitive compensation and an excellent benefits program, including medical, dental, and vision plans, company‑paid holidays, matching 401(k), and more.

About Inertia Inertia is advancing fusion energy by leveraging the only successful achievement of fusion ignition pioneered at the U.S. Department of Energy’s Lawrence Livermore National Laboratory.
