Own the full lifecycle of real-time embedded software for microreactor and test hardware, from requirements and architecture through implementation, verification, deployment, and maintenance. Develop production C/C++ software, integrate custom electronics, define hardware-facing interfaces, implement fault handling, debug cross-disciplinary system issues, and support qualification testing. Lead design and code reviews, establish best practices, and mentor engineers while collaborating with electrical, controls, reactor software, safety, systems, and test teams.

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.

Execute direct and indirect procurement, purchase order management, supplier performance tracking, delivery follow-up, and procure-to-pay improvements. Partner with Finance and Accounts Payable on approvals, invoice matching, exceptions, and payment visibility. Build dashboards and reports, maintain supplier data, document procurement procedures, and support scalable supply chain processes in a fast-changing hardware environment.

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.

Design and analyze heat exchangers, piping, manifolds, and pressure-containing components for advanced energy systems. Evaluate thermal stresses, fluid mechanics, structural integrity, thermal expansion, and mechanical loads. Support materials selection, fabrication, testing, hardware validation, failure investigations, and design improvements. Collaborate with engineering, manufacturing, materials, quality, and testing teams to mature reliable hardware from concept through production.

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.
