The Community + Brand Manager will shape external brand experiences, manage events, enhance community engagement, and create branded materials while coordinating with cross-functional teams.

As a Frontend UX/UI Software Engineer, you'll design and implement applications for fusion machine operators, improving their workflows with real-time data visualizations and user-friendly interfaces, while collaborating closely with engineering teams.

The Senior Experimental Scientist will lead the development and analysis of plasma diagnostics for fusion generators, ensuring alignment with operational needs and optimizing performance through collaboration with various engineering and science teams.

Lead development of data foundations for fusion systems: ingest and model experimental and operational time-series data, build data schemas and pipelines, create ontologies and metadata frameworks, and develop AI-enabled workflows and decision-support tools for anomaly detection, analysis, and operational reporting.

Design, develop, and support LabVIEW-based control and data-acquisition systems (PXI/cRIO) for fusion R&D and manufacturing. Build GUIs, implement state-machine control architectures, integrate sensors and industrial hardware (PLCs, microcontrollers), implement communications protocols, perform verification, commissioning, and operational support, and produce technical documentation.

Entry-level mechanical engineer responsible for hardware design of fusion generator prototypes. Own subsystem designs (electromagnetic, structural, fluid, thermal, control), create 3D CAD models, perform ANSYS analyses, run design reviews, iterate designs, work hands-on with technicians, troubleshoot integrated hardware, and learn from senior engineers.

Define and evolve operational systems enabling manufacturing execution across material flow, inventory, logistics, production, and shop floor operations. Translate manufacturing challenges into scalable processes, partner cross-functionally to deliver solutions, establish standards, improve visibility through metrics and dashboards, drive continuous improvement, and mentor engineers to scale operations for production readiness.

The Principal Experimental Scientist will lead RF pre-ionization development for fusion generators, integrating various technical inputs and enhancing plasma performance through rigorous experimental design and execution.

The Internal Communications Specialist will lead Helion's internal communication efforts, ensuring alignment and engagement through storytelling, newsletters, and innovative communication strategies across teams.

The Senior Technical Writer will develop and maintain technical documentation for fusion systems by collaborating with operations and engineering teams to translate complex processes into usable procedures and manuals.

Design, prototype, test, and integrate mechanical diagnostic instrumentation for plasma experiments. Translate experimental needs into mechanical solutions, perform CAD and FEA, run experiments, analyze data, and lead root-cause analysis and continuous improvements.

Run and analyze kinetic/Particle-in-Cell (PIC) simulations (WarpX or similar) to study plasma behavior for FRC systems; develop input decks and PICMI scripts, perform parameter scans and validation, analyze outputs with Python or similar tools, compare results to experiments, and produce visualizations and reduced data to inform experimental and modeling teams.

Design, build, deploy, calibrate, and operate plasma diagnostics for fusion generators. Support experimental campaigns, troubleshoot hardware, analyze diagnostic data, document procedures, and collaborate cross-functionally to improve device performance.

Own and improve automated manufacturing test systems for high-voltage electrical assemblies, develop production test processes and software, integrate instrumentation and DAQ, ensure safe repeatable test methods, troubleshoot equipment, and collaborate cross-functionally to enable production ramp and maintain test station reliability.

Manage the HERCULES program, overseeing $20M in research funding, technical project delivery, and stakeholder communication to ensure alignment with Helion's scientific objectives.

As a Principal Electrical Engineer, you'll design and operate RF circuits and diagnostic systems for fusion generators, ensuring performance optimization and compliance with safety standards. You'll collaborate across disciplines, guide experimental workflows, and mentor junior engineers while leading technical efforts in a fast-paced environment.

The Principal Capacitor Engineer will lead the design and development of custom high-voltage capacitors for fusion generators, overseeing all aspects from concept to high-volume manufacturing and providing technical leadership to the engineering team.

As a Build Engineer, you will manage the manufacturing and assembly of fusion generator subsystems, ensuring manufacturability and collaborating with teams throughout the design process.

The Senior Mechanical Engineer will design subsystems for fusion generators, apply engineering principles, and troubleshoot issues, reporting to the Senior Manager of Engineering.
