About the role
Overview:
As a Stress Engineer at Radiant, you own structural loads, vibration, and dynamic analyses for Kaleidos, the first portable microreactor. You will ensure structural integrity across manufacturing, transport, handling, deployment, and operation, collaborating with multiple engineering teams. You’ll model and validate loads, perform FEA, and support tests and regulatory interfaces. This role offers hands-on work in a fast-paced environment with a mission to enable rapid, safe nuclear power deployment. Compensation / Benefits stock options medical plans with family coverage One Medical memberships vision and dental coverage life/accident/hospital/critical illness insurance paid parental leave and pregnancy leave for CA employees
Responsibilities:
Develop static, dynamic, and transient load cases for reactor systems, supports, and transport configurations Perform structural dynamics analyses (modal, random vibration, shock, sine, fatigue) Model nonlinear reactor response with explicit dynamics for transient seismic/transport events Define transport/handling environments (road, rail, air, sea) Generate load cases for sizing, margins, and verification plans Conduct FEA using ANSYS, Abaqus, or similar tools Collaborate with design engineers on hardware architecture, materials, and joint design Support test planning and correlation (shaker tests, modal surveys, structural verification) Create and maintain analysis documentation for reviews and regulatory interfaces Contribute to failure investigations and design improvements Help establish loads/dynamics/verification best practices
Key requirements:
Bachelor’s degree in Mechanical, Aerospace, Structural, or related field 4+ years in stress, loads, dynamics, or structural analysis for complex mechanical systems Strong fundamentals in structural mechanics, dynamics, and vibration Experience with FEA on metallic and composite structures Proficiency with ANSYS, Abaqus, and/or Nastran Familiarity with design allowables, safety factors, and margin-of-safety methodologies Ability to communicate results clearly to technical and non-technical stakeholders Cross-functional collaboration Effective communication Problem-solving under ambiguity FEA (ANSYS, Abaqus, Nastran) Explicit dynamics modeling (LD-Dyna) Modal, random vibration, shock, fatigue analysis
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
