Обязанности
- is seeking a Stress Engineer to own and execute structural loads, vibration, and dynamic analyses for complex mechanical systems associated for Kaleidos, the world's first portable microreactor and supporting hardware. You will play a critical role in ensuring structural integrity and survivability across all phases of the product lifecycle, including manufacturing, transportation, handling, deployment, and operational environments.
- This role requires a hands-on engineer who is comfortable working in ambiguous, fast-paced environments and collaborating closely with structures, mechanical design, thermal, nuclear, and test teams.
- Develop and own static, dynamic, and transient loads for reactor systems, support structures, and transport configurations.
- Perform structural dynamics analyses, including modal, random vibration, shock, sine vibration, and fatigue assessments.
- Implement explicit dynamics simulations to model nonlinear reactor response under transient seismic and transportation event cases.
- Define and analyze transportation and handling environments, including shock and vibration from road, rail, air, or sea transport.
- Generate load cases and environments to support structural sizing, design margins, and verification plans.
- Conduct finite element analyses (FEA) using tools such as ANSYS, Abaqus, or similar tools.
- Collaborate with design engineers to influence hardware architecture, material selection, and joint design.
- Support test planning and correlation, including shaker tests, modal surveys, and structural verification testing.
- Develop and maintain analysis documentation, reports, and requirements for internal reviews and regulatory interfaces.
- Contribute to failure investigations, root cause analyses, and design improvements
- Help establish best practices for loads, dynamics, and structural verification within a growing engineering organization.
Требования
- Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Structural Engineering, or a related field.
- 4+ years of professional experience in stress, loads, dynamics, or structural analysis for complex mechanical systems.
- Strong fundamentals in structural mechanics, dynamics, and vibration.
- Experience with finite element modeling and analysis of metallic and composite structures.
- Proficiency with industry-standard FEA tools (e.g., ANSYS, Abaqus, Nastran).
- Familiarity with design allowables, safety factors, and margin-of-safety methodologies.
- Ability to work cross-functionally and communicate analysis results clearly to both technical and non-technical stakeholders.
- Experience in aerospace, launch, defense, nuclear, or heavy industrial hardware environments.
- Dynamics modeling software experience (LD-Dyna, Abaqus explicit, or other).
- Background in shock and vibration testing and test-article correlation.
- Knowledge of fatigue, fracture mechanics, and bolted joint analysis.
- Experience defining or interpreting environmental specifications and requirements.
- Master’s degree or PhD in a relevant engineering discipline.
- Familiarity with nuclear, spaceflight, or safety-critical system requirements.
- Must be willing to work extended hours and weekends as necessary to accomplish our mission.
- Must work 100% onsite at El Segundo HQ.

- 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. ’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, is on track to test its first reactor at the Idaho National Laboratory this summer, with initia
