Xcimer Energy leverages decades of research on Inertial Fusion Energy (IFE) combined with groundbreaking new laser architecture. Our mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. Xcimer has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by leading investors, Xcimer is uniquely positioned to deliver limitless, clean, fusion power to combat climate change. Join us in powering a better world with inertial fusion!

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

\n$160,000 - $200,000 a yearCandidates may be considered for other positions at Xcimer Energy, and our actual base salary will be determined on an individual basis and may vary based on job-related knowledge and skills, education, and experience. The range is published in accordance with Colorado Equal Pay for Equal Work Act and California Equal Pay Act.\n

Equal Employment Opportunity

Xcimer Energy is proud to be an Equal Opportunity/Affirmative Action Employer and is committed to attracting, retaining, and developing a highly qualified, diverse, and dedicated work force. Xcimer Energy hires and promotes people on the basis of their qualifications, performance, and abilities. We support the establishment and maintenance of a workplace that fosters trust, equality, and teamwork, in which all employees recognize and appreciate the diversity of individual team members. We provide all qualified applicants for employment and employees with equal opportunities for hire, promotion, and other terms and conditions of employment, regardless of their race, color, religion, gender, sexual orientation, gender identity, national origin/ethnicity, age, physical or mental disability, genetic factors, military/veteran status, or any other status or characteristic protected by federal, state, and/or local law. Xcimer Energy will consider for employment qualified applicants with criminal histories in a manner consistent with applicable federal, state, and local laws.

Benefits

Xcimer offers a comprehensive benefits package designed to support employee health, well-being, and long-term success. Benefits include medical, dental, and vision coverage; basic and supplemental life insurance; short- and long-term disability; paid parental leave for employees at the time of birth or adoption; and a 401(k) with a company match of up to 6%. Eligible employees also receive equity, allowing them to share in the company’s long-term success.

Xcimer operates under a flexible Paid Time Off (ATO) approach. Rather than a fixed number of vacation days, employees are trusted to take the time they need to rest and recharge while meeting the expectations of their role and team. In addition, employees receive paid sick time, 13 company-paid holidays, and an annual paid company shutdown. Benefits are available to regular employees, including part-time and fixed-term roles, as well as interns, with eligibility varying by benefit.
