Last Energy is a pioneering US technology company focused on fleet-wide deployment and operation of next-generation nuclear assets. With projects actively underway in the United States and United Kingdom, Last Energy co-locates their proprietary 20 MWe power plant in clusters, with strategic deployment near AI data centers, defense installations, and industrial facilities. Specializing in high-throughput manufacturing and supply chain efficiency, Last Energy is revolutionizing nuclear power delivery for rapid deployment and scalability.
We are seeking a Senior Mechanical Engineer that can own the end-to-end development of mechanical systems. You will be working on conceptual design, CAD modeling, and scaled prototyping of novel industrial hardware solutions to modify, enhance, and integrate power equipment in order to unlock the productization of a micro nuclear power plant.
Key Duties & Responsibilities
- Collaborate with a multidisciplinary team to plan, design, and execute large industrial capital projects in the power generation sector.
- Mechanical design, authoring technical reports, and generating analysis requirements for components
- Performing Finite Element Analysis (FEA) on structural components, both steady state and transient
- Contribute to designing and analyzing tanks, pressure vessels, pumps, heat exchangers and other related components
- Integrating various mechanical systems and components to ensure they work together seamlessly
- Assemble, calibrate, and test hardware prototypes at the bench top scale and oversee these activities for third party contractors at the full scale
- Designing fixtures and tooling to aid in the assembly, testing, and manufacturing processes
- Optimize designs for ease of manufacturing, which includes considering assembly methods, tolerances, and minimizing manufacturing complexities
Qualifications
- Bachelor's degree in Mechanical Engineering or a related field
- 4+ years of experience in mechanical engineering or mechanical design for innovative product development, R&D, manufacturing, fabrication or related fields
- Proficiency in CAD software (e.g., SolidWorks, AutoCAD)
- Adept at solving complex structural, thermal, and fluid dynamics challenges utilizing advanced techniques and software
- Proficient in Finite Element Analysis (FEA) and Computational Fluid Dynamics (CFD) using relevant software tools including ANSYS, LS-DYNA, Nastran, Radioss, or similar
- Strong analytical and problem-solving skills
- Knowledge of materials selection, stress analysis, and thermal design
- Excellent communication skills and the ability to work in cross-functional teams
- Creative thinking and a passion for innovation in mechanical design
