Diesel Generator Engineer information

What is a diesel generator engineer?

A Diesel Generator Engineer is responsible for the installation, maintenance, troubleshooting, and repair of diesel-powered generators. They ensure that generators operate efficiently and reliably, often conducting inspections, performance tests, and preventive maintenance. Their role may also involve diagnosing faults, replacing faulty components, and ensuring compliance with safety and environmental regulations. Diesel Generator Engineers work in various industries, including construction, healthcare, data centers, and manufacturing, where backup or continuous power is essential.

What are some common daily responsibilities for a diesel generator engineer?

Diesel Generator Engineers typically spend their days performing routine inspections, troubleshooting faults, conducting repairs, and maintaining generator units to ensure optimal performance. They may also handle load testing, document service activities, and calibrate control systems to meet operational standards. Collaboration with electricians, facility managers, and other maintenance teams is common to coordinate repairs or preventive maintenance schedules. This hands-on and team-oriented environment means you'll often be balancing urgent repairs with planned service tasks, keeping reliability and safety as top priorities.

What are the key skills and qualifications needed to thrive in the diesel generator engineer position, and why are they important?

To thrive as a Diesel Generator Engineer, you need solid mechanical and electrical engineering knowledge, experience with diesel power generation systems, and relevant engineering qualifications. Familiarity with diagnostic tools, generator control systems, and industry certifications such as NFPA 110 or manufacturer-specific training is often required. Strong problem-solving skills, attention to detail, and effective communication are valuable soft skills for this position. These abilities help ensure generator reliability, minimize downtime, and support safe and efficient operation in demanding environments.

Job description

About Radiant
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.
About the Role
Radiant is seeking a talented Principal Power Systems Engineer to lead the design, modeling, and validation of electrical power systems supporting our nuclear microreactor platform. You will play a critical role in defining how power is generated, conditioned, controlled, and delivered to customers across grid-connected, islanded, and rapidly deployable environments.
In this role, you will own power system studies from early architecture tradeoffs through detailed modeling, testing, and system validation. You'll collaborate closely with electrical design, controls, turbomachinery, nuclear, thermal, and software teams to ensure safe, stable, and reliable power delivery under a wide range of operating and contingency conditions. This role is central to commercializing Earth's first mass-produced portable nuclear reactors.
Responsibilities & Duties:
  • Own power system architectural design for microreactor-based power generation systems operating in grid-connected and islanded modes.
  • Develop single-line diagrams of the power system for single- or multiple-reactor configurations.
  • Develop FMEAs to identify system behavior during component/system failures and identify redundancy paths.
  • Evaluate system behavior during disturbances such as load steps, faults, breaker operations, and loss-of-generation events.
  • Size energy storage systems for reactor cold start and variable load demands.
  • Own synchronization of multiple reactors in a microgrid and multiple reactors tied to grid.
  • Collaborate cross-functionally with the power conversion team to understand generator requirements and design power systems that can integrate seamlessly.
  • Participate in software-in-the-loop (SIL), hardware-in-the-loop (HIL), and system-level testing to validate/verify system performance.
  • Support system checkouts, commissioning, and testing of all power requirements
  • Regulatory compliance of power systems, including testing methods to verify power quality.

Required Qualifications & Skills:
  • B.S. in Electrical Engineering with an emphasis in power systems or control systems.
  • 5+ years of experience designing power systems for generation, microgrids, or mission-critical power systems.
  • Experience with sizing and integrating high-voltage battery systems with power electronics.
  • Strong experience with power system modeling and simulation tools (e.g., PSCAD, ETAP, PSS®E, Simulink, or equivalent).
  • Solid understanding of inverters, grid converters, DC/DC converters, rotating generation, and power system control modes (grid-forming, grid-following, droop control).
  • Experience in analyzing system stability, protection behavior, and fault response in complex electrical systems.
  • Ability to clearly communicate technical concepts and results to cross-functional teams.

Desired Qualifications & Skills:
  • M.S. in Electrical Engineering or related discipline.
  • Experience in power electronics development for high-power, medium-voltage equipment, including transformers, switchgear, inverters, active rectifiers, DC/DC converters, and generator controls.
  • 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.
  • Experience mentoring junior engineers or leading technical efforts on complex programs.

Additional Requirements:
  • 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.
Benefits and Perks
  • Stock: Substantial incentive stock plan for all full-time employees.
  • Medical: 100% up to base silver level plan for employee + 50% dependents, offers up to Platinum plans.
  • One Medical: Sponsored memberships for employees and their dependents.
  • Vision: 100% top tier plan coverage + 50% for dependents.
  • Dental: 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.

Radiant compensates people for impact and invests in those who continue to raise the bar. Radiant's new hire compensation package includes base salary, substantial equity grants, and comprehensive health benefits. Total compensation and level are determined through a rigorous evaluation of interview performance, experience, education, and qualifications, and are designed to support continued growth as scope, responsibility, and impact expand at Radiant.
