Jobs at Commonwealth Fusion Systems

The Senior Manager will lead Accounting Operations, overseeing accounts payable, payroll, and compliance while improving processes and managing staff development.

As a Senior Controls Engineer, you'll lead equipment conceptual development, provide technical leadership, create system architectures, and mentor junior engineers while ensuring compliance with safety standards.

Serve as primary systems engineer for critical utility subsystems in R&D: integrate mechanical, electrical, and software components; lead hands-on troubleshooting/commissioning; author specifications and requirements; manage schedules and budgets; standardize workflows and SOPs; drive cross-functional alignment among ME, EE, and SW teams.

Support procurement activities including creating purchase orders, supplier onboarding, RFQ issuance and analysis, contract review, order tracking, invoice resolution, and providing updates to internal customers while adhering to supply chain and export compliance policies.

Design, implement, and verify production-quality control software for real-time and PLC platforms. Integrate software with hardware and testbeds, develop operator interfaces, improve developer tooling, and collaborate across engineering teams to meet functional requirements for advanced R&D equipment.

Manage tactical production and procurement planning to support ramp-up in volume; translate engineering BOMs into actionable plans; align suppliers, supply chain, and manufacturing schedules; monitor supply risk, communicate blockers, negotiate resource allocation, and create tools/process improvements.

Lead development of an integrated fusion power plant fuel-cycle model and simulation toolkits. Build and validate unit-operation and multiphysics models, define R&D milestones, create engineering layouts and documentation, collaborate cross-functionally, own simulation tools, guide colleagues, and identify validation needs and opportunities to improve economics and integration.

Serve as SME for dimensional management and inspection strategy for HTS magnet production. Translate GD&T into manufacturable requirements, architect inspection systems, lead MSA/Gage R&R and SPC efforts, disposition NCRs with risk-informed decisions, create PFMEAs and quality plans, mentor QC inspectors, and stabilize processes through capability analysis to enable SPARC project production.

Lead and scale a global, hardware-intensive supply chain for commercial fusion power plants. Build strategy and supplier roadmaps, negotiate complex partnerships, architect supply chain systems, and manage a ~100-person team to enable multi-plant annual delivery.

Perform mid- to large-scale precision alignments and dimensional inspections using portable 3D metrology (laser trackers, scanners, software). Collect, organize, and analyze metrology datasets, evaluate measurement uncertainty, communicate results, collaborate with design and manufacturing teams, and support assembly activities while maintaining equipment and following safety and onsite procedures.

The Staff Controls and Software Engineer will develop control systems for fusion energy equipment, collaborate with R&D and engineering teams, and oversee project design, testing, and optimization.

Lead and grow a process engineering team to develop and stabilize vacuum-based thin film processes (sputtering, thermal). Create SOPs, train staff, manage vendors, drive continuous improvement with equipment and integration engineering, and implement data/LIMS and DOE-driven process controls to meet technical milestones.

Develop, select, and maintain metrology and measurement systems. Create SOPs, train staff, manage data via LIMS/MES, coordinate metrology vendors, and ensure safety and quality in challenging environments.

Lead full-cycle, high-volume recruiting across technical and non-technical departments. Build hiring manager relationships, improve recruiting processes and candidate experience, source top talent, run interview trainings, and collaborate with TA and HR teams to shorten time-to-fill and drive diverse hiring.

As a Diagnostician, you will oversee the design and implementation of diagnostic sub-systems for the SPARC tokamak, ensuring operational efficacy and safety while collaborating with a diverse team.

Define and document assembly processes and work instruction packets for large, complex SPARC tokamak subsystems. Collaborate with system, tooling, and field teams to plan lifts, part movement, tooling, traceability (ERP/MES), and safety measures; troubleshoot non-conformances and improve assembly work order processes. Support on-site assembly activities.

The Director, Project Development will oversee the development of the first grid scale commercial fusion power plants, managing permits, project schedules, budgets, and teams to ensure successful delivery by the early 2030s.

Coordinate recruiting activities including scheduling video and on-site interviews, greeting candidates, maintaining the Lever ATS, posting jobs, supporting sourcing and intake/debrief meetings, and helping manage candidate logistics and travel while ensuring a positive candidate experience and adherence to site safety protocols.

Lead design, simulation, testing, and commissioning of medium-voltage power electronic converter systems. Define component specifications, develop test plans, troubleshoot systems, coordinate vendors, and document engineering designs to deliver high-power electrical equipment for fusion power applications.

Lead and scale manufacturing operations, implement lean and continuous improvement programs, integrate new technologies, manage quality/compliance and budgets, build high-performing teams, and collaborate with R&D, Supply Chain, Quality and EHSS to drive production results and operational excellence.
