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.

Lead technical recruiting for aerospace and technology roles by partnering with hiring managers, sourcing passive candidates, managing pipelines, advising on market dynamics, building talent maps, and closing high-quality talent. The role also involves recruiting analytics, employer branding collaboration, process improvement, and support for critical technical hiring. Requires onsite work in Torrance, California, with occasional long hours and weekends as needed.

Develop and maintain quality processes for nuclear microreactor manufacturing, including nonconformance management, calibrated hardware procedures, material certification, supplier qualification, root-cause investigations, and regulatory compliance. Collaborate with engineering, production, and supply chain teams to mitigate quality risks, improve processes, and document procedures and findings. The role requires supporting critical milestones, potentially including long hours and weekends.

Own end-to-end electrical harness design for testbed and safety-class nuclear systems, including CAD routing, schematics, component selection, safety requirements, release packages, BOMs, supplier qualification, quality processes, and in-house builds. Direct harness technicians, manage tooling and workmanship standards, support supplier communications and nonconformances, and administer harness design software and automation.

Develop infrastructure and tooling for cloud and on-premises applications and compute workloads. Responsibilities include improving deployment automation, integrating systems, creating Grafana dashboards and alerts, standardizing Python data projects, migrating cluster infrastructure to Rocky Linux and Warewulf, building storage and compute-usage tools, optimizing cloud costs, and documenting quality processes. The role is onsite in Torrance, California, and includes substantive software and systems projects.

Develop and test embedded software connecting to reactor hardware. Responsibilities include hardware-in-the-loop validation, failure investigation, automated testing, telemetry instrumentation, system monitoring, and integrating signals into HMI and Grafana. The intern will complete starter assignments and a long-duration technical project culminating in a deliverable and presentation while working onsite with cross-functional engineering teams.

Develop inspection methods for mechanical and electrical systems, qualify inspection equipment, characterize measurement uncertainty, validate hardware, and improve inspection repeatability. The intern will collaborate across design, manufacturing, testing, supply chain, and materials teams while owning a long-term technical project culminating in a presentation.
