Job Description & How to Apply Below
Position: Senior Optical Engineer, High-Power Laser Systems
Location: Livermore

Overview:

We are seeking an experienced and innovative Optical Engineer to advance high power laser system design and testing capabilities for Inertia’s fusion energy program. A key element is development of 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).

This position initially involves the design of optical test facilities, and subsequent co-design of the integrated beamline systems.

What You’ll Do:

  • Develop creative optical designs for beyond state-of-the-art high-average power laser systems

  • Perform ray-tracing and stray light analysis for a wide range of optical systems design.

  • Undertake optical analysis (hot spots, ghosts, stray light, beam profiles)

  • Interface with mechanical engineering design teams for integrated systems

  • Create optical prints and work with supply chain

What You’ll Bring:

  • BS or MS in Physics, Photonics, Optical Engineering or related field.

  • 5+ years experience in optical design relevant to high energy lasers

  • Strong expertise in the use of optical design tools such as Zemax, Code V, FRED, etc.

Salary & Benefits:

  • The base salary range for this role is $120,000 - $215,000;
    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!
