Jobs at Helion Energy

Lead and scale a multidisciplinary Plant Control Software team building embedded, supervisory, networking, and data systems that control and observe a fusion power plant. Own delivery across firmware, application, networking, and data layers, coordinate cross-discipline schedules with hardware teams, establish engineering principles and processes, and hire and grow engineers.

Provide unarmed security for Helion's Everett headquarters by patrolling buildings and grounds, monitoring access control and CCTV, enforcing site directives, collaborating with law enforcement, and delivering customer-focused interactions while standing or walking up to 12-hour shifts.

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.

Lead and scale the indirect procurement function: hire and manage a procurement team, develop and execute category strategies across software, services, hardware, capex and R&D, run end-to-end sourcing and negotiations (MSAs, SOWs), partner with stakeholders, and improve cost, supplier performance, and supply chain resilience.

Lead strategic sourcing and category management for capital equipment and complex engineered systems. Build supplier base, negotiate contracts, drive cost reduction, secure capacity, and partner cross-functionally with engineering, manufacturing, finance, and program teams to support fusion program milestones.

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

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.

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

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.

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.

As a Senior Test Engineer, you will design and sustain electrical test systems for validating PCBAs and high-voltage assemblies, while ensuring reliability and safety in support of fusion generators.

Lead mechanical hardware design for high-performance structural systems in fusion devices, mentor a team, and drive architectural decisions.

As a Cybersecurity Software Engineer, you will enhance product security for firmware, software, and server infrastructure. You'll implement security best practices and tools, manage secrets, and perform code reviews while collaborating with engineering 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.

Design and optimize high-power electrical systems for fusion generators, focusing on energy delivery and systems reliability while mentoring engineers.

Manage R&D engineers focused on technology testing and development for fusion energy. Oversee testing initiatives, drive cross-functional collaboration, and support team growth.

The role involves simulating FRC dynamics with MHD code, analyzing circuit responses, and communicating findings. Requires collaboration and technical rigor.
