Full Job Posting
- Plan, analyze, and execute environmental testing profiles, including ground vibration testing (GVT) of spacecraft hardware and modal testing for finite element model validation.
- Construct detailed finite element models (FEM), superelements, and test display models optimized for dynamic analyses (such as modal, random vibration, sine vibration, shock, and vibro-acoustic profiles).
- Perform structural hand calculations and numerical simulations to evaluate material strength margins, structural notching limits, and core mode shapes.
- Collaborate with test engineers to define comprehensive environmental test plans that establish instrumentation layouts, accelerometer locations, and safe response limits.
- Provide dedicated, on-site engineering support during modal, vibration, and acoustic testing to ensure test targets, sensor calibrations, and safety objectives are met.
- Perform signal analysis and evaluate test telemetry data across both time and frequency domains to troubleshoot hardware vibration anomalies.
- Prepare rigorous technical reports, structural verification packages, and presentations to communicate analysis results, findings, and design recommendations to internal engineering leads and commercial clients.
- Other duties as assigned.
- High level critical thinking, mathematical reasoning, and a detail-oriented structural engineering mindset.
- Strong interpersonal, communication, and technical documentation skills with the ability to summarize complex load data clearly.
- Willingness and ability to travel to external testing facilities and work actively on-site at vibration/acoustic test chambers.
- Bachelor’s Degree in Mechanical Engineering, Aerospace Engineering, or a highly related field plus 5-10 years of experience in structural dynamics.
- 3-5 years of direct experience writing environmental test plans, executing vibration/shock tests, and using empirical data to correlate structural models.
- Proficiency in performing analytical simulations and structural finite element modeling utilizing Nastran or equivalent solvers.
- Proficiency in coding, automated scripting, and processing time-series data using MATLAB or Python.
- Familiarity with relevant aerospace testing and analysis standards, such as NASA-STD-5001, SMC-S-016, or MIL-STD-1540.
- Experience with Simcenter (NX) Nastran or Beta CAE products (ANSA, META, EPYLISIS) for finite element modeling and post-processing is a plus.
