Staff Structures Engineer
About The Position
Radiant is seeking a highly motivated Staff Structures Engineer to design and develop critical structures within its Kaleidos transportable nuclear microreactor. The role focuses on creating efficient, reliable structures that facilitate fission while withstanding extreme temperature environments and meeting volumetric constraints. The engineer will conduct trade studies, select materials, perform detailed structural analysis, and contribute to assembly, integration, and testing. The role is described as instrumental to the development of a new commercial reactor design. The position owns critical structures and subsystems, including transportable shielding, the container system, and high-temperature graphite and metallic systems. It involves analyzing structural integrity with hand calculations and finite element tools, developing manufacturing and assembly instructions and test plans, managing bills of materials and suppliers, and owning subassembly schedules and subsystem risk analysis. The engineer will also collect requirements and communicate expertise and feedback to engineers in other functional areas. This position is 100% onsite at Radiant's El Segundo headquarters. Extended hours and weekends may be necessary. The compensation package includes base salary, equity grants, and health benefits; compensation and level depend on interview performance, experience, education, and qualifications.
Requirements
- Bachelor’s degree from an accredited institution in Mechanical, Aeronautical, Civil, or Structural Engineering.
- At least 7 years of experience designing structures.
- At least 5 years of experience performing stress analysis using hand calculations and finite element tools such as Abaqus, Ansys, FEMAP, or similar.
- Must be willing to work extended hours and weekends as necessary to accomplish the mission.
- Must work 100% onsite at the El Segundo headquarters.
Nice To Haves
- Experience designing multi-component assemblies in CAD, such as NX or similar.
- Experience designing hardware that was manufactured, deployed, and iteratively improved.
- Experience resolving thermal expansion issues in designs.
- Experience working with interdisciplinary teams.
- Solid understanding and application of GD&T.
- Proficiency with both hand-calculation analytical methods and higher-fidelity finite-element-based analysis methods.
- Ability to derive free-body diagrams for systems with which one was not previously familiar.
- Self-motivation and strong organizational, written, and oral communication skills.
- Experience using text-based software development tools.
Responsibilities
- Own critical structures, including mass-efficient transportable shielding systems, the container system, and high-temperature graphite and metallic systems.
- Conduct trade studies and develop designs that meet program requirements.
- Perform detailed thermomechanical analysis, including static strength and durability/fatigue, and dynamic analysis, including vibration and shock, using hand calculations and finite element tools to determine structural integrity and margins of safety.
- Develop and execute manufacturing and assembly instructions and test plans.
- Create and manage a Bill of Materials (BOM).
- Find and develop suppliers for components.
- Own subassembly design, manufacturing, and test schedules.
- Own subsystem risk analysis (FMEA).
- Collect requirements and provide expertise and feedback to engineers in other functional areas through clear, constructive communication.
Benefits
- Substantial incentive stock plan for all full-time employees.
- Medical coverage up to the base silver-level plan for the employee and 50% coverage for dependents, with plans up to Platinum available.
- Sponsored One Medical memberships for employees and dependents.
- Vision coverage for the employee at 100% of the top-tier plan and 50% for dependents.
- Dental coverage for the employee at 100% of the top-tier plan, with orthodontia extra, and 50% for dependents.
- Voluntary life, accident, hospital, and critical illness benefits, as well as commuter and FSA/HSA benefits, are offered as employee-contributed benefits.
- Eight weeks of paid parental leave for all parents, plus additional paid pregnancy leave for California employees.
- A fully covered Nuclear Engineering Certificate Program with Penn State University for eligible employees.
- Daily catered lunch, free snacks, and drinks.
- Flexible PTO policy and remote workday allocation.
- Company and team-bonding events, happy hours, and in-person camaraderie.
