Design and develop high-efficiency, high-reliability semiconductor components for pulsed power systems in fusion generators. Lead requirements gathering, prototyping, testing, simulation, validation, and rapid development cycles. Collaborate across electrical, mechanical, and physics disciplines; work with semiconductor fabricators; analyze performance data; and document designs, specifications, test results, and findings.

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.

Administer and optimize Helion’s enterprise applications, including Atlassian tools, integrations, cloud environments, and SaaS platforms. Manage access controls, SSO/SCIM, compliance, audit logging, data flows, vendors, upgrades, and migrations. Partner with business and technical teams to configure systems, automate workflows, troubleshoot incidents, support releases, and maintain reliable IT infrastructure.

Lead Helion’s Controls Engineering team in delivering reliable LabVIEW- and NI-based control and data acquisition systems for fusion R&D, high-voltage testing, plasma technology, manufacturing, and future power plant applications. Set technical direction and engineering standards, oversee development and deployment, collaborate cross-functionally, and coach and grow the team while balancing rapid experimentation with scalable system architecture.

Administer identity, access, enterprise applications, and security systems across Entra ID, Active Directory, Microsoft 365, and Atlassian. Automate employee and service-account lifecycle processes using PowerShell and APIs, manage access reviews, respond to security events through Microsoft Sentinel, support integrations and application security reviews, resolve Jira-based requests, document procedures, and improve operational processes. The role is onsite in Seattle with one remote day weekly and may require after-hours incident response.

Own manufacturing, assembly, tooling, and deployment for first-of-a-kind fusion generator subsystems. Develop work instructions, support nonconformance resolution, collaborate across engineering and production, and improve low-volume build processes. Ensure manufacturability, configuration control, hardware quality, and execution speed across multidisciplinary mechanical, electrical, and fluid systems.

Own the manufacturing, assembly, tooling, and deployment of first-of-a-kind fusion generator subsystems. The role develops build definitions and work instructions, supports technician teams, improves low-volume manufacturing processes, collaborates across design, production, and integration teams, and ensures configuration control and hardware quality. Responsibilities span multidisciplinary hardware including structures, mechanical assemblies, power transmission, vacuum systems, electromagnets, capacitor systems, harnessing, and radiation shielding.

Design, build, and maintain software for fusion plant control, diagnostics, automation, data acquisition, operator workflows, and real-time system coordination. Integrate software with sensors, actuators, controllers, databases, visualization tools, and complex hardware. Collaborate across electrical, firmware, mechanical, IT, operations, and science teams while improving platform reliability, usability, and scalability. Develop prototypes and production systems, debug cross-disciplinary issues, and support the full software lifecycle onsite.

Operate and improve high-energy fusion experiments and pulsed-power systems. Own experiment readiness, pre-shot setup, system checks, troubleshooting, root cause analysis, vacuum system reliability, and diagnostic interpretation. Drive safe, repeatable machine performance and continuous operational improvement while collaborating with engineering, science, and production teams.

Lead company-wide compensation strategy, including salary, hourly pay, incentives, equity programs, manufacturing pay structures, compensation cycles, and executive advising. Partner with Finance, Talent, People Business Partners, and leadership on budgets, equity forecasting, governance, offers, promotions, and employee education. Build scalable programs for technical, corporate, and large hourly manufacturing teams while balancing strategic ownership with hands-on execution.

Own the end-to-end accounts payable process, including invoice processing, two- and three-way matching, payment execution, vendor record maintenance, reconciliations, exception resolution, and month-end close support. Partner with Finance, Supply Chain, Procurement, Receiving, and business stakeholders to maintain controls, prevent fraud, resolve discrepancies, support audits, test systems, and improve AP processes. The role is onsite in Seattle and may require extended hours or weekends during critical deadlines.

Lead integration and test activities for fusion generator prototypes, collaborating with teams to ensure operational readiness and manage engineering projects.

Executes internal and external corporate communications, including weekly newsletters, town halls, executive messaging, speaking engagements, media relations, and major announcements. Manages communications calendars, coordinates cross-functional contributors, develops accurate stories, tracks engagement and media performance, and improves programs using feedback and data. The role requires excellent writing, sound judgment, strong organization, autonomy, and the ability to manage sensitive information and competing deadlines onsite in Everett, Washington.

Lead the electrical engineering team, overseeing high-voltage circuit design, project management, and cross-disciplinary collaboration to enhance machine performance for fusion power systems.

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.
