Senior Structural Engineer, Concrete
About The Position
Radiant is seeking a highly motivated Senior Structures Engineer to design and develop critical concrete and precast structural systems for its manufacturing and deployment sites. The role addresses the design of efficient, reliable concrete structures that can withstand extreme thermal and seismic environments while meeting site and program constraints. The engineer will conduct trade studies, select materials, perform detailed structural analysis, and support assembly, integration, and testing. The work enables manufacturing, fueling, and safe-storage infrastructure for Radiant’s microreactors. The position includes ownership of concrete structures such as spent-fuel dry-cask storage systems, facility foundations, and precast concrete elements used in manufacturing and site operations. The engineer will coordinate with other functional areas, suppliers, and fabricators, and manage structural subsystem schedules, materials, risk analyses, and construction, fabrication, and test plans. This position is 100% onsite at Radiant’s El Segundo headquarters. The employee must be willing to work extended hours and weekends as necessary.
Requirements
- Bachelor’s degree from an accredited institution in Civil, Structural, or Mechanical Engineering.
- At least 5 years of experience designing concrete or reinforced concrete structures.
- At least 4 years of experience performing structural analysis using both hand calculations and finite element tools such as Abaqus, Ansys, SAP2000, or similar.
- Must be willing to work extended hours and weekends as necessary.
- Must work 100% onsite at the El Segundo headquarters.
Nice To Haves
- Active Professional Engineer (PE) license; not required.
- Experience with reinforced concrete design codes such as ACI 318 or similar.
- Experience designing precast concrete systems, including handling, transport, and erection considerations.
- Experience with dry-cask storage design or spent nuclear fuel storage systems.
- Experience with seismic design or qualification of concrete structures.
- Experience with nuclear or other critical-facility structural design.
- Experience designing hardware or structures that were fabricated, deployed, and iteratively improved.
- Experience resolving thermal expansion and thermal gradient issues in concrete designs.
- Experience working with interdisciplinary teams, including mechanical, civil, and geotechnical disciplines.
- Solid understanding and application of GD&T and construction tolerancing.
- Proficiency in hand-calculation analytical methods and higher-fidelity finite element analysis methods.
- Ability to derive free-body diagrams for systems not previously encountered.
- Self-motivation and strong organizational, written, and oral communication skills.
- Experience using text-based software development tools.
Responsibilities
- Own critical concrete structures, including spent-fuel dry-cask storage systems, factory and facility foundations, and precast concrete elements supporting manufacturing and site operations.
- Conduct trade studies and develop designs meeting program requirements for static, thermal, and seismic loading conditions.
- Perform detailed reinforced and precast concrete structural analysis, including static strength and durability analysis, and dynamic analysis for seismic qualification, using hand calculations and finite element tools to determine structural integrity and margins of safety.
- Develop and execute construction, fabrication, and test plans for precast and cast-in-place concrete elements.
- Create and manage a Bill of Materials (BOM).
- Find and develop suppliers and fabricators for precast concrete components.
- Own subassembly and structure design, fabrication, and test schedules.
- Own risk analysis (FMEA) for concrete structural subsystems.
- 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 at 100% for the employee and 50% for dependents, with plans available up to Platinum.
- Sponsored One Medical memberships for employees and dependents.
- Vision coverage at 100% for the top-tier plan and 50% for dependents.
- Dental coverage at 100% for the top-tier plan, with orthodontia extra, and 50% for dependents.
- Voluntary life, accident, hospital, and critical illness coverage, plus commuter and FSA/HSA benefits, offered as employee-contributed benefits.
- Eight weeks of paid parental leave for all parents, plus additional paid pregnancy leave for California employees.
- Nuclear Engineering Certificate Program with Penn State University, fully covered for eligible 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.
