## Description

Radiant is seeking a talented Senior Manager, Power Systems, to build and lead the team that designs, models, and validates electrical power systems for our nuclear microreactor platform. You will manage a team of power systems and power electronics engineers, set technical direction and priorities, and ensure the team delivers safe, stable, and reliable power across grid-connected, islanded, rapidly deployable, and space-based environments.

In this role, you will guide your team through power system studies from early architecture tradeoffs through detailed modeling, testing, and system validation, while also driving the development of in-house power electronics, including converters, inverters, and generator controls, needed to support both terrestrial and space-based reactor platforms. This role is central to commercializing Earth's first mass-produced portable nuclear reactors, and to extending that capability beyond Earth.

Responsibilities & Duties

 * Build, manage, and grow a team of power systems and power electronics engineers, including hiring, mentoring, and performance management.
 * 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.
 * 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.
 * Oversee SIL/HIL and system-level testing, commissioning, and regulatory/power-quality compliance.
