The Head of NBI Development leads Realta Fusion's Neutral Beam Injector R&D team, driving the design, analysis, and integration of NBI systems and subsystems for our magnetic mirror fusion devices. This senior technical leadership role demands deep scientific and engineering expertise, proven ability to lead multidisciplinary teams, and the vision to translate physics requirements into manufacturable, reliable hardware. The ideal candidate combines hands-on technical credibility with strategic leadership, thriving in a fast-paced environment where engineering decisions directly impact our path to commercial fusion energy. The Head of NBI Development owns the NBI roadmap from experimental devices through pilot plant and commercial deployment.
Job Responsibility:
Define and execute the technical roadmap for NBI systems across all company devices and future commercial applications
Identify technology gaps between current capabilities and commercial fusion requirements, particularly for steady-state operation
Lead make-vs-buy decisions for NBI components and subsystems based on technical maturity, cost, and schedule
Establish design standards, qualification procedures, and configuration management practices for NBI systems
Represent Realta in external collaborations with national laboratories, universities, and NBI technology suppliers
Own the performance, reliability, and availability of all NBI systems across company experimental devices
Lead troubleshooting of system failures and drive root cause analysis to prevent recurrence
Develop and implement preventive maintenance programs to minimize unplanned downtime
Optimize NBI operating parameters to maximize plasma heating efficiency and experimental productivity
Ensure safe operation and regulatory compliance for high-voltage systems and radiation-producing equipment
Serve as technical lead for external NBI procurement contracts and vendor partnerships
Manage technical specifications, delivery schedules, and acceptance testing for purchased NBI systems
Oversee commissioning activities and development of operational procedures for new NBI installations
Lead internal R&D programs for novel NBI technologies required for steady-state fusion operation
Drive development of high-duty-cycle ion sources, neutralizers, and thermal management solutions
Evaluate emerging technologies including negative ion sources, RF ion sources, and advanced accelerator designs
Manage prototype development, testing, and validation of next-generation NBI subsystems
Develop cost models and manufacturing strategies for commercial-scale NBI production
Build and manage NBI scientific team including ion source specialists, beamline scientists, and diagnostics experts
Coordinate with experimental physics teams to align NBI capabilities with plasma heating requirements
Work with project management to maintain schedules, budgets, and risk mitigation plans for NBI programs
Collaborate with Director of Fusion Facilities on NBI infrastructure and safety requirements
Partner with mechanical and electrical engineering teams on NBI system integration
Ensure documentation, knowledge capture, and lessons learned across all NBI activities
Requirements:
Advanced degree in physics, nuclear engineering, electrical engineering, or related field
15+ years experience in NBI system or accelerator beamline development
5+ years leading teams of 5+ people
Track record delivering complex systems from concept through commissioning
Deep expertise in neutral beam injection systems, ion sources, or related particle accelerator technologies
Track record of managing complex experimental systems in fusion, accelerator, or plasma research environments
Experience with NBI diagnostics, beam optics modeling, and performance analysis
Proven ability to lead, mentor, and develop high-performing scientific teams
Strong communication skills across technical and business audiences
