Structural Analyst / Structural Engineer

Senior Structural Analyst / Structural Engineer Busek Co. Inc. – Natick, MA Busek is seeking a Senior Structural Analyst / Structural Engineer to join our Design & Analysis Team supporting the development of advanced spacecraft propulsion systems and aerospace hardware. This is one of the most critical engineering needs within the organization as we continue to expand internally and reduce reliance on outsourced structural analysis work. This role is ideal for an engineer who enjoys owning analyses end-to-end, working closely with hardware teams, and solving complex aerospace structural challenges in a fast-paced R&D environment. The selected candidate will perform and lead structural analyses for flight and development hardware using finite element methods (FEM). Analyses include modal, random vibration, sine, and shock environments typically encountered in aerospace applications. Most analyses are performed using ANSYS, though strong fundamentals and relevant aerospace structural experience are valued above specific software expertise. This position works closely with design engineering, systems engineering, and test engineering to support hardware development, qualification testing, requirements verification, and anomaly resolution.

Random vibration analysis Sine vibration analysis Shock analysis Develop and evaluate component-level and system-level finite element models (FEMs) Import and clean CAD geometry for analysis Define boundary conditions, interfaces, and load cases Select appropriate element types and modeling approaches Apply meshing best practices including convergence studies and mesh quality verification Interpret, validate, and communicate analysis results Perform classical hand calculations to validate FEM assumptions and results Analyze aerospace hardware including brackets, fittings, interconnects, and structural subassemblies Evaluate structural margins, failure modes, and material behavior Model and assess bolted joints and extract bolt forces from FEM results Cross-Functional Engineering Support Collaborate closely with design engineers to reduce structural risk early in the design process Support test engineering efforts including: Accelerometer placement recommendations Interpretation of vibration spectra and gRMS profiles Correlation of test and analytical data Failure investigations and root cause analysis Work with systems engineering to translate requirements into structural analysis inputs and compliance verification Technical Communication Prepare clear and concise technical reports for: Internal design reviews Customer deliverables Qualification and certification documentation Present assumptions, methodologies, and conclusions to both technical and non-technical stakeholders Technical Leadership Provide informal mentoring and technical guidance to junior engineers Contribute to continuous improvement of modeling methods, analysis standards, and engineering processes
