Director of Test Engineering, Radiant Nuclear

• 10+ years of experience in test engineering, with at least 3 years in a leadership role building or managing test teams or programs
• Hands-on experience designing and building test setups for mechanical, thermal, or fluid systems
• Deep experience with instrumentation and data acquisition systems (sensor selection, DAQ hardware, signal conditioning, automated data collection)
• Experience writing test plans, procedures, and reports with the rigor required for engineering decision-making
• Track record of establishing standard test methods and processes for an organization
• Experience leading teams of technicians and test engineers
• BS in Mechanical Engineering, Aerospace Engineering, or related discipline
• Must be willing to work extended hours and weekends as necessary to accomplish our mission

Desirable

• Radiant is seeking a Director of Test Engineering to own the design, build, and execution of developmental and qualification test programs that validate our reactor systems and components
• This is a hands-on leadership role: you will build and run a service organization that designs test setups, develops instrumentation and data acquisition systems, executes test campaigns, and delivers high-quality data and reports to engineering teams
• This role is responsible for establishing standard methods, tooling, and infrastructure that allow Radiant to test hardware at the pace our development schedule demands
• The test organization will operate as an internal service to design engineering teams—responsive, fast, and easy to work with
• Own the end-to-end execution of developmental, qualification, and acceptance test campaigns for reactor components and subsystems
• Design and build test setups—from simple bench-level fixtures to complex thermal-hydraulic loop rigs
• Develop and maintain test plans and procedures that define objectives, instrumentation requirements, success criteria, data deliverables, and safety controls
• Execute test campaigns, including hands-on operation of test equipment and supervision of technicians
• Deliver data packages and test reports to engineering teams with the quality and traceability needed to support design decisions and regulatory documentation
• Design and build instrumentation systems: sensor selection, signal conditioning, DAQ hardware configuration, and wiring
• Develop automated data collection, monitoring, and reduction workflows for real-time insight during test campaigns
• Establish data management standards: file structures, naming conventions, metadata capture, and archival
• Establish standard methods for recurring test types: pressure testing, leak checks, thermal cycling, vibration/seismic, environmental exposure, dimensional verification
• Build reusable test infrastructure and tooling that can be adapted across programs (KDU, KV1, and future production units)
• Create templates and standard operating procedures that lower the barrier for new test campaigns
• Build and lead a test engineering team (technicians, test engineers, instrumentation specialists)
• Coordinate Responsible Engineers on development test objectives, acceptance test and qualification test execution
