About the role

This role is central to commercializing Earth's first mass-produced portable nuclear reactors, and to extending that capability beyond Earth.
Set team priorities and roadmaps in partnership with leadership from power conversion, controls, nuclear, and software.
Communicate progress, risks, and results to executive leadership and cross-functional stakeholders.

Build, manage, and grow a team of power systems and power electronics engineers, including hiring, mentoring, and performance management.
Lead the team that owns power system architecture, single-line diagrams, and synchronization strategy for single and multi-reactor configurations, grid-connected and islanded.
Direct FMEAs and disturbance analysis (load steps, faults, breaker operations, loss-of-generation) to validate system stability and protection behavior.
Own architecture, sizing, and integration of off-the-shelf hardware for energy storage and power conversion.
Lead in-house power electronics development (converters, inverters, generator controls) to support earth and space-based reactor platforms.
Radiant is an El Segundo, CA-based startup building the world's first mass-produced, portable nuclear microreactors.
Radiant's unique, practical approach to nuclear development leverages modern software engineering to rapidly deliver safe, factory-built microreactors that use existing, well-qualified materials.
