About the role

Xcimer Energy builds on decades of research in Inertial Fusion Energy (IFE), combined with a groundbreaking new laser architecture, to accelerate the deployment of fusion power plants. Our mission is to deliver clean, limitless fusion energy fast enough to meet global decarbonization goals. Xcimer has assembled a world-class team spanning tough tech, fusion science, and advanced manufacturing, with a proven track record of rapid execution. Backed by leading investors, we are uniquely positioned to bring inertial fusion power from prototype to reality. Join us in powering a better world with fusion.

This is a full-time, onsite role based at our headquarters in Denver, CO.

As a Senior Structural Analyst, you will perform structural and mechanical analyses using classic hand calculations and finite element model (FEM) simulations to support design, manufacturing, assembly, and test. A thorough understanding of structural behavior, static and dynamic loading, and margins is required to achieve system performance and cost-optimized designs. You will create concise, accurate analysis documentation; perform peer reviews of analysis and reports; and provide analysis guidance to design engineers and junior analysts. As hardware matures from prototype builds through integrated test campaigns, you will also help resolve nonconformances, support root-cause investigations, and enable rapid iteration through close collaboration with engineering and operations.

Responsibilities

Perform structural and mechanical analyses for opto-mechanical, thermal-mechanical, fluid-structure interactions, and support-structure hardware to support design, manufacturing, assembly, and test.

Validate finite element models based on internal and external data.

Create analysis documentation that is concise, accurate, and traceable; produce reports supporting design reviews and test readiness.

Perform peer reviews of analysis and reports generated by other team members and incorporate feedback.

Provide analysis guidance to design engineers and mentor junior analysts; help establish best practices for modeling, margins, and documentation.

Support prototype builds and test operations by troubleshooting structural/mechanical issues, dispositioning nonconformances, and recommending corrective actions.

Qualifications

Education: B.S. degree in mechanical engineering (or a related engineering field).

Experience: 8+ years of structural/mechanical analysis experience supporting engineered hardware (e.g., energy, aerospace, automotive, or high-precision machines).

Experience with one or more commercial FEA tools (e.g., Altair, ANSYS, Abaqus, Nastran) and best practices for model verification/validation.

Demonstrated knowledge of load paths and stress analysis bolted joints, weldments, frames, mounts, and pressure-containing components.

Demonstrated experience with static and dynamic FEM simulations.

Strong fundamentals in classical mechanics of materials and structural sizing methods (hand calculations, closed-form solutions).

Knowledge of engineering materials, manufacturing processes, and how they influence structural performance, tolerances, and reliability.

Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Desired

M.S. degree in mechanical engineering (or equivalent advanced degree/experience).

Experience supporting test campaigns, instrumentation/strain gauging, and correlation of analysis to test results.

Proficiency with Altair Optistruct and Radioss

Experience with nonlinear materials, vibration, fatigue, creep, high temperatures, and ceramic materials.

Experience applying ASME Boiler and Pressure Vessel Code requirements to analyses.

Demonstrated experience using scripting languages (e.g., Python, MATLAB, VBA) to automate analyses, post-process results, and improve repeatability and efficiency.

CAD and PLM experience (NX and Teamcenter)

Multiphysics simulation development and validation
