Senior Manager, Power Systems
About The Position
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.
Requirements
- B.S. in Electrical Engineering with an emphasis in power systems or control systems.
- 8+ years of experience designing power systems for generation, microgrids, or mission-critical power systems.
- 3+ years of experience in a formal people management role.
- Experience with sizing and integrating high-voltage battery systems with power electronics.
- Track record developing power electronics for high-power, medium-voltage equipment, including transformers, switchgear, inverters, active rectifiers, DC/DC converters, and generator controls.
- Background in leading teams with power system modeling and simulation tools (e.g., PSCAD, ETAP, PSS®E, Simulink, or equivalent).
- Solid understanding of power system control modes (grid-forming, grid-following, droop control).
- Experience in analyzing system stability, protection behavior, and fault response in complex electrical systems.
- Proven ability to lead and develop engineering teams while remaining technically hands-on.
- Ability to clearly communicate technical concepts and results to cross-functional teams and leadership.
Nice To Haves
- M.S. in Electrical Engineering or related discipline.
- 5+ years of experience in a formal people management role.
- Experience with islanded power systems supporting critical loads.
- Familiarity with interconnection requirements, grid codes, and relevant IEEE or utility standards.
- Experience in modeling dynamic loads and fast-changing electrical demand.
- Exposure to nuclear, aerospace, defense, or other highly regulated industries.
- Track record of building or scaling an engineering team on complex, safety-critical programs.
Responsibilities
- 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.
Benefits
- Substantial incentive stock plan for all full-time employees.
- 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans.
- Sponsored memberships for employees and their dependents.
- 100% top tier plan coverage + 50% for dependents.
- 100% top tier plan coverage, orthodontia extra, 50% for dependents.
- Voluntary life, accident, hospital, critical illness, commuter and FSA/HSA are offered as employee contributed benefits.
- 8-weeks of paid parental leave for all parents. Additional paid pregnancy leave for CA employees.
- Daily catered lunch.
- Free snacks and drinks.
- Flexible PTO policy.
- Remote workday allocation.
- Company and team-bonding events, happy hours and in-person camaraderie.
- Beautiful El Segundo headquarters close to the Pacific Ocean.
