Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Build and lead a team of power systems and electronics engineers to design and validate electrical systems for nuclear microreactors. Oversee power system architecture, stability analysis, and the development of in-house power electronics for terrestrial and space-based platforms.
Requires a B.S. in Electrical Engineering with 8+ years of experience in power systems and 3+ years in formal people management. Must have a proven track record in power electronics development and proficiency with modeling tools like PSCAD or Simulink.
Radiant is an El Segundo, CA-based startup building the world’s first mass-produced, portable nuclear microreactors. The company’s first reactor, Kaleidos, is a 1-megawatt, fail-safe microreactor that can be transported anywhere power is needed and run for up to 5 years without refueling. Portable nuclear power with rapid-deploy capability can replace similar-sized diesel generators and provide critical asset support for hospitals, data centers, remote sites, and military bases. 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. Founded in 2020, Radiant is on track to test its first reactor at the Idaho National Laboratory this summer, with initial customer deliveries beginning in 2028.
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.
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.
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.
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.
Must be willing to work extended hours and weekends as necessary to accomplish our mission.
Must work 100% onsite at Radiant's El Segundo HQ.
