CAD System Engineer

Radiant is an El Segundo CA-based startup building the worlds first mass-produced portable nuclear microreactors. The companys 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. Radiants 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 CAD Systems Engineer to own the NX and Teamcenter environment our mechanical engineers use every day reporting to our PLM Architect. This is where engineering workflows get designed standards and templates are built and automation keeps design data clean as we scale. Teamcenter expertise is scarce and in growing demand and working directly under an architect in a hardware-driven organization is a great way to learn a system most hardware companies rely on. Youll grow into deeper ownership of standards customization and configuration while supporting the design and build of the first mass-produced portable nuclear reactor.

• Develop and maintain the NX CAD environment: templates customization files role-based configurations Check-Mate rules part families reusable component libraries and default settings across the organization.

• Establish document and enforce organization-wide standards for CAD modeling drafting and PLM data entry to ensure data consistency and integrity.

• Partner with engineering on item and BOM structure workflow design revision and release processes and data cleanup

• Automate the repetitive parts of the engineering data workflow from bulk data operations to reporting.

• Own user and access administration in Teamcenter: accounts groups roles permissions and organizational structure as the company grows

• Manage client deployments and upgrades for NX and Teamcenter across engineering workstations packaging rollout patching and validating changes in a test environment before they go live.

• Troubleshoot licensing from the user side coordinating with the systems engineer who owns the license servers and drive vendor support cases to resolution.

• Write the documentation and run the training that stops the same question arriving twenty times.

• Grow into deeper platform ownership as you build expertise under the PLM Architect.

• Bachelors degree in Mechanical Engineering another engineering discipline or a STEM field.

• 1 years in engineering support design drafting component engineering systems administration or a comparable technical role

• Exposure to a PLM PDM or CAD environment: NX Teamcenter Windchill 3DEXPERIENCE SolidWorks PDM or comparable. Depth is welcome but not required.

• Experience working with engineers gathering requirements and turning them into actionable steps

• Organized and dependable with attention to detail.

• Genuine appetite to learn this platform deeply

• 3 years in engineering support design drafting component engineering systems administration or a comparable technical role

• Hands-on NX experience as a user designer or drafter

• Background in mechanical design drafting component engineering or manufacturing moving toward the systems side

• Any Teamcenter administration exposure: BMIDE workflow design multi-tier environments

• Scripting aptitude to automate repetitive work.

• SQL comfort for reporting and data investigation

• ITAR EAR or 10 CFR 810 controlled environment experience

• Must be willing to work extended hours and weekends as necessary to accomplish our mission.
