Jobs at Radiant Industries

Own Radiant's external media presence: build reporter and podcaster relationships, secure executive bookings and feature coverage, coordinate investor amplification, prepare spokespeople, manage crisis communications, monitor competitors, and report media metrics.

Develop and govern design standards, requirements, and verification methodologies for mass-produced portable nuclear reactors. Provide design review oversight, approve qualification test campaigns, guide engineers through requirement-driven design processes, and ensure hardware meets Radiant standards across design, manufacturing, testing, and operations.

Design and implement DOE/NRC-compliant operational procedures for reactor operators, qualify as an operator, and collaborate with engineers to improve operator interfaces, digital twin scenarios, and human-machine interfaces. Support testing, hardware- and software-in-the-loop procedures, and iterative improvements to ensure safe, efficient commissioning, testing, and operations of portable nuclear microreactors.

Design and implement DOE/NRC-compliant operational procedures and interfaces for portable microreactors. Qualify as an operator, collaborate with engineers on HMI and software tools, support simulator and digital twin testing, and refine hardware-in-the-loop procedures to ensure safe, efficient commissioning and operations.

Lead day-to-day accounting operations, manage month- and year-end close, oversee fixed assets, inventory, payroll accounting, reconciliations, and internal controls. Support audits, implement systems/process improvements, collaborate cross-functionally, and mentor junior accounting staff.

Design and develop mechanisms for safety and control features in the new commercial reactor. Conduct trade studies, analyze designs, and manage integration processes.

Hands-on role assembling, integrating, and preparing turbomachinery hardware (compressors, turbines, rotors, bearings, seals, motors) for first-article testing. Develop assembly instructions, alignment and torque procedures, support rotor stacking, balancing, and tooling. Collaborate with design, test, and manufacturing teams, document builds, troubleshoot issues, and iterate on assembly processes while receiving mentorship and growing technical skills.

Own full-cycle technical recruiting to source, assess, and close top talent across technical and corporate roles. Partner with hiring managers and leadership to define hiring strategies, develop structured processes, drive proactive sourcing and employer branding, represent Radiant at events, and use data to improve recruitment outcomes.

Independently source and qualify leads across commercial verticals; run full sales cycles from discovery to term sheet; negotiate commercial documents; build and maintain a high-quality pipeline; develop proposals and grant letters; learn siting, licensing, permitting, and project finance to close deals; represent Radiant externally.

Build and run Radiant's supplier reliability program: qualify and onboard suppliers, author quality documentation, execute audits, develop capability-improvement plans, define procurement acceptance strategies, monitor supplier performance, manage inspections and non-conformances, and partner with engineering and manufacturing to ensure parts meet nuclear-quality requirements.

Lead and grow a team designing, modeling, and validating electrical power systems and power electronics for portable nuclear microreactors. Own system architecture, stability and protection analysis, hardware integration, SIL/HIL testing, and regulatory/power-quality compliance across grid-connected, islanded, and space environments. Coordinate cross-functionally and report to executive leadership.

Program, set up, and operate 3- to 5-axis CNC mills and lathes to produce precision components. Translate engineering drawings and GD&T into manufacturable parts, select tooling and parameters, troubleshoot floor issues, optimize programs and processes, and collaborate with engineering and quality teams to improve manufacturability and cycle times.

Support design, build, and maintenance of NI PXI-based HIL test benches. Configure test hardware, integrate with Digital Twin, execute test procedures, collect and document data, troubleshoot hardware, and assist senior engineers with electrical integration and harness assembly.

Develop and maintain Reactor Operator training materials, qualification records, and evaluation tools to DOE/NRC standards. Embed with engineering, test, and operations teams to capture lessons learned, manage documentation lifecycles in configuration-controlled systems, support test plans and regulatory documents, and deliver instructional sessions.

Lead legislative affairs, engage with Congress, shape policy for advanced nuclear systems deployment, and develop congressional strategy supporting federal programs.

The Senior Test Engineer will develop and enhance operational procedures for nuclear microreactor testing, ensuring compliance and efficiency while collaborating with a multidisciplinary team.

The Mechanical Engineer will design fluid systems, perform thermal analysis, manage assembly, select components, and conduct testing to support a nuclear microreactor project.

The Director of Regulatory Affairs will lead regulatory and licensing strategies and ensure compliance with the NRC, driving product development and market entry.

Design and develop production and fabrication equipment for mass-produced portable nuclear microreactors. Create equipment for semi-remote fueling/defueling, fabricate and analyze assemblies, and qualify suppliers while collaborating closely with design and manufacturing teams in a 100% onsite role.

Lead the design and validation of electrical power systems for portable nuclear microreactors, collaborating with cross-functional teams on system performance and safety.
