Jobs at Fuse (f.energy)

Design, build, program, integrate, and deploy robotic manufacturing cells for high-voltage pulsed-power hardware. Responsibilities include robot selection, end-effector and fixture design, machine vision and sensor integration, PLC and motion-control integration, safety architecture, automated assembly and inspection, maintenance practices, and production-line development. The role partners with mechanical and electrical engineers, supports design for automated assembly, and helps grow the robotics team in a fully onsite startup environment.

Own day-to-day corporate IT operations, including account provisioning, device deployment, MDM administration, SaaS and identity management, helpdesk support, network troubleshooting, endpoint compliance, documentation, asset inventory, procurement, and vendor relationships. The role supports macOS and Windows environments, provides onboarding assistance, and operates as the primary IT resource for the San Leandro office with occasional after-hours support and travel.

Own security strategy and technical controls across AWS, infrastructure as code, software development, identity, SaaS, control systems, and data pipelines. Responsibilities include cloud security, DevSecOps, security monitoring, incident response, access control, endpoint baselines, risk tracking, compliance preparation, and security awareness. The role is the company’s first dedicated security position and requires close partnership with IT and engineering, occasional travel, and after-hours incident response availability.

Lead capture and proposal efforts from teaming strategy through submission for government and commercial opportunities. Write, edit, and manage technical, management, and past-performance volumes; coordinate engineering, contracts, leadership, and other stakeholders; and maintain compliance matrices, templates, content libraries, style guides, and documentation. Translate complex fusion technology into persuasive proposals, technical narratives, product documentation, and go-to-market content while managing deadlines in a fast-moving startup environment.

Build and manage Fuse’s in-house accounting function across multiple entities. Responsibilities include financial close and reporting, AP/AR, treasury, tax filings, R&D tax credits, audits, government contract accounting, internal controls, compliance, and scalable accounting systems.

Build coupled fusion-device simulation models, radiation and surrogate models, diagnostic data pipelines, Bayesian inference systems, and uncertainty quantification tools. The role covers pulsed-power circuits, plasma dynamics, neutron and X-ray production, machine lifetime modeling, and HPC-enabled computation. The scientist will write production-grade numerical software, validate models against experimental diagnostics, document assumptions, and eventually grow a simulation team.

Design, commission, operate, and maintain high-vacuum cryopumping and 4 K liquid-helium cooling systems for a pulsed-power fusion facility. Responsibilities include cryogenic infrastructure management, vacuum diagnostics, instrumentation integration, preventive maintenance, vendor coordination, safety procedures, pressure-vessel compliance, and staff training.

Designs, simulates, integrates, and commissions large-scale fluid systems for transformer oil and deionized water in a pulsed-power fusion facility. Responsibilities include fluid circuit design, CFD modeling, dielectric fluid management, water conditioning, thermal analysis, P&ID development, documentation, troubleshooting, and interdisciplinary integration with high-voltage, structural, vacuum, and pulsed-power teams.

Work directly with the CEO and executive team on high-priority, ambiguous initiatives. Responsibilities include organizing cross-functional projects, creating structure and follow-through, and handling evolving business needs such as events, facilities, recruiting, communications, customer initiatives, investor preparation, and supply chain. The role requires strong initiative, accountability, communication, adaptability, and willingness to work extended hours, weekends, relocate to San Leandro, and occasionally travel.

Shoot, edit, and deliver cinematic films showcasing Fuse’s fusion-energy machines, people, tests, and technical work. Own the complete production workflow, including camera, lighting, audio, editing, color, scripting, concepts, and final delivery. Produce launch films, technical explainers, and social content, primarily as a one-person crew. Maintain a searchable footage library and collaborate with the creative team on cohesive branding. The role is on-site in San Leandro, California, may require relocation, occasional travel, and extended hours or weekends.

Build Fuse’s commercial partnerships from the ground up, focusing on semiconductor and electronics companies with radiation-hardening and testing needs. Own the full sales cycle, identify and prioritize partners, negotiate complex joint development agreements and strategic investments, secure stakeholder approval, and develop scalable approaches to commercialize Fuse’s capabilities. The role requires deep semiconductor market knowledge, technical fluency, commercial judgment, local relocation to San Leandro, extended hours when needed, and some business travel.

Leads company-wide FP&A, budgeting, forecasting, long-range modeling, cash and liquidity planning, capital allocation, KPI reporting, fundraising support, and strategic investment analysis. Partners with the CEO, Accounting, investors, auditors, banks, and government-program stakeholders. Builds scalable financial infrastructure and supports pricing, unit economics, contract profitability, resource allocation, and the future Finance organization for a capital-intensive hardware company.

As an intern at Fuse, you will assist in building the TITAN fusion generator, collaborating with a team to achieve project goals.

Provide high-touch executive support to the founder: manage calendars, travel, logistics, communications, and cross-team coordination. Anticipate needs, remove blockers, prepare documents, and maintain discretion while enabling fast-paced decision-making and flawless operations.
