Job summary

Realta Fusion Inc. seeks an NBI Scientist (Laser & Photonics) to build laser and optical-cavity expertise for photoneutralization in next-generation fusion energy systems.

You will define architectures, support integration with NBI design, and translate optical requirements into practical system designs. The role spans development, modeling, testing, and optimization of laser and optical systems, requiring collaboration across scientific and engineering teams to meet milestone-driven objectives

Qualifications

• PhD or strong equivalent experience in lasers, photonics, atomic physics, accelerator laser systems, precision optics or a related field.
• High-power laser systems and resonant/enhancement optical cavities; cavity locking, stabilization and alignment.
• Laser diagnostics, high-reflectivity optics, thermal stability, vacuum optical systems and laser safety.
• Ability to translate photodetachment and beam requirements into an experimental cavity/laser program with measurable milestones.
• Fusion experience is helpful but not required; deep laser/cavity expertise is more important.

Responsibilities

• Primary NBI Science technical interface for photoneutralization collaboration.
• Define the first experimental architecture, cavity requirements, diagnostics, optical-loss budget and scaling path.
• Build sufficient laser/cavity knowledge within NBI Science to inform HAMMIR NBI architecture and integration decisions.
• Create a development path from bench/cavity demonstration to integration with future negative-ion beam systems.
