The Role

Capella, an IonQ company, is looking for a seasoned Structural Analyst to help refine our current analysis tools that support the design, development, and qualification of hardware for space applications. The candidate will advance Capella’s FEA modeling and analysis abilities by developing a standardized analysis approach with associated documentation, creating detailed FEA models of the spacecraft and components used for vehicle level analysis and to output environments for design and test, and support the improvement of designs.  You will have the unique opportunity to come in at an early stage and develop the tools and processes that will be used to guide Capella’s growth.

The successful candidate will work closely with design, manufacturing, systems, test, and program teams to ensure hardware meets performance, reliability, and mission requirements while maintaining aggressive development schedules.

The ideal candidate possesses deep expertise in finite element analysis (FEA), structural dynamics, fracture mechanics, composite and metallic structures, and aerospace design practices. Experience supporting commercial and government spaceflight programs is highly desirable.

Responsibilities

• Perform detailed structural analyses for spacecraft, payload, and ground support hardware.

• Develop, correlate, and maintain high-fidelity finite element models for static, dynamic, thermal, and nonlinear analyses.

• Generate component level dynamic environments (vibe/shock), acoustic, loads, and thermal limits from launch environments and thermal environments.

• Generate structural margins of safety in accordance with customer and industry standards.

• Provide analytical recommendations that support engineering trade studies and critical project decisions.

• Partner with and mentor design engineers to improve structures for strength, stiffness, weight, manufacturability, and cost.

• Evaluate structural performance under launch, transportation, and operational environments.

• Perform analyses including:

• Linear and nonlinear static analysis

• Modal and frequency response analysis

• Random vibration

• Shock analysis

• Buckling analysis

• Fatigue and fracture mechanics

• Thermal stress analysis

• Contact and large-deformation analysis

• Develop, validate, and update Craig-Bampton reduced-order models (Component Mode Synthesis models) for integrated vehicle dynamic analyses and customer interface requirements, including delivery of Craig-Bampton models to SpaceX and other launch service providers in accordance with provided specifications.

• Prepare structural analysis reports, certification documentation, and technical presentations for internal and external customers.

• Support hardware qualification and acceptance testing through pre-test predictions and post-test correlation.

• Strong understanding of vibration testing:

• Aid in fixture design and test setup (accelerometer locations, etc.)

• Understanding of notching and other force limiting techniques

• Ability to review test response results and evaluate impacts on components when levels may be exceeded

• Participate in design reviews including PDR, CDR, TRR, and FRR.

• Support anomaly investigations, root cause analyses, and corrective action implementation.

• Collaborate with manufacturing and test teams to resolve structural issues throughout production and integration.

Requirements

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related engineering discipline

• 5+ years of structural analysis experience supporting aerospace or spaceflight hardware.

• Ability to make technically sound decisions under schedule constraints.

• Self-motivated with the ability to manage multiple projects simultaneously.

• Attention to detail with a commitment to e
