Top Tech Jobs & Startup Jobs

Designs turbomachinery components and assemblies for nuclear reactors, from architecture and CAD layouts through detailed drawings, manufacturing, assembly, and testing. Responsibilities include materials and manufacturing-process evaluation, tolerance and interface definition, supplier and manufacturing support, design improvements, test hardware and tooling development, and collaboration with aerodynamic, structural, thermal, rotordynamics, and test engineers.

Supports government affairs, policy research, stakeholder engagement, strategic communications, international market research, and commercial business development for advanced nuclear microreactors. Responsibilities include monitoring legislation and federal agencies, preparing briefings and policy materials, developing communications content, assessing international markets, researching prospective customers and partners, maintaining stakeholder databases, and supporting government and business engagements.

Build and administer enterprise systems and workflows connecting supply chain, manufacturing, quality, engineering, procurement, and finance. Develop AI-enabled automations, integrations, anomaly detection, data pipelines, and human-in-the-loop processes using Python, SQL, APIs, and workflow tools. Maintain master data, system configuration, testing, documentation, audit readiness, and user training while improving operational visibility and exception management. The role is onsite in Torrance, California, with occasional travel and support for urgent milestones.

Design, analyze, qualify, and deploy high-temperature heat exchangers, piping, manifolds, and mechanical interfaces. Responsibilities include thermal and structural analysis, pressure and thermal-expansion evaluation, materials and fabrication support, test development, hardware integration, operating-limit definition, and failure investigation. The role requires collaboration across engineering, manufacturing, materials, quality, and testing teams to deliver reliable energy hardware.

Leads the design, analysis, testing, qualification, and deployment of safety-significant reactor structures. Performs thermo-mechanical and structural analyses, defines architectures and design margins, develops engineering documentation, leads component and system testing, and collaborates with manufacturing, licensing, procurement, and other engineering teams. The role supports first-of-a-kind hardware in a highly regulated, multidisciplinary environment.

Build and own a reusable software platform for hardware testing, including equipment interfaces, automated test sequencing, synchronized data acquisition, live monitoring, fault handling, operator tools, and post-test analysis. Integrate instruments, sensors, controllers, and custom electronics while supporting reliable operation across multiple test stands. Collaborate with multidisciplinary engineering teams during hardware bring-up, test campaigns, and root-cause investigations, establishing software testing, deployment, version control, configuration management, and documentation practices.

Lead supply chain strategy for electronics and electromechanical commodities from prototyping through full-rate production. Responsibilities include supplier identification and development, design-for-manufacturability reviews, quality and documentation compliance, make-versus-buy analysis, should-cost modeling, supplier negotiations, performance reporting, and critical-path execution. The role partners closely with engineering, quality, and suppliers in a fast-paced startup environment and requires travel of up to 40%.

Leads manufacturing process development and production launch for nuclear reactor assemblies. Responsibilities include DFM/DFA, assembly process flows, tooling and equipment development, manufacturing documentation, mBOMs, configuration control, readiness reviews, floor troubleshooting, cross-functional collaboration, and mentoring engineers. The role supports hardware from engineering release through prototype, qualification, final integration, and scalable production while meeting rigorous quality and traceability requirements.

Own key monthly, quarterly, and annual close activities, including journal entries, reconciliations, accruals, variance analysis, financial reporting, audits, tax support, and compliance. Support government contract accounting, manufacturing and inventory accounting, technical accounting, internal controls, ERP improvements, and process automation while helping build Antares’ accounting infrastructure as it scales into production.

Design, analyze, qualify, and deploy heat exchanger systems and associated piping for advanced energy applications. Responsibilities include thermal and structural analysis, piping flexibility, pressure and thermal-load evaluation, material and fabrication development, test article and validation testing, hardware integration, failure investigation, and design improvement. The role requires collaboration across engineering, manufacturing, materials, quality, and testing teams to deliver reliable, manufacturable high-temperature hardware.
