Top Tech Jobs & Startup Jobs

Performs advanced materials testing, analytical equipment operation, precision fabrication, test setup validation, troubleshooting, data analysis, and technical documentation. Develops and executes ASTM-based and custom test methodologies, designs fixtures, maintains calibration and traceability, supports engineering decisions, and mentors junior technologists. The role also requires collaboration with engineers and adherence to radiation safety and contamination-control practices in a high-risk technical environment.

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.

Participate in a 12-week onsite internship developing fusion power technology. Design and test hardware across mechanical, structural, fluid, thermal, electromagnetic, and control subsystems; investigate and resolve hardware issues on integrated fusion generators; apply engineering principles; and collaborate with experienced engineers on next-generation systems.

Own Helion’s fusion power plant system architecture, top-level requirements, subsystem interfaces, and verification planning. Lead trade studies, design reviews, integration risk mitigation, configuration management, and change control. Develop Interface Control Documents and ensure traceability from plant-level objectives to implemented hardware. Partner across electrical, mechanical, controls, science, software, business, and supplier teams to drive technical consensus and scale systems engineering processes for production power plants.
