BAE Systems is seeking a Principal Mechanical Engineer to serve as a Subject Matter Expert (SME) in structural analysis. This role is critical in ensuring the structural integrity, durability, and survivability of innovative mechanical solutions for dynamic electronic military systems. The ideal candidate will possess a deep background in structural mechanics and finite element analysis (FEA), excellent leadership skills, and a proven track record of driving structural validation from the IRAD/Proposal phase through to the Qualification phase. Key Responsibilities Technical Leadership & Structural Oversight: Provide lead structural oversight for entire projects, complex modules, or high-stress LRUs/boxes, operating with high autonomy to ensure all hardware meets rigorous structural requirements. Analysis Authority: Hold primary responsibility and authority for structural analysis. Utilize advanced simulation techniques to predict failure modes, optimize weight, and ensure structural margins are maintained. Business Pursuit & Customer Engagement: Support key business pursuits by defining structural requirements and environmental constraints that meet customer needs; serve as the primary technical point of contact for structural integrity during customer interfaces. Structural Validation & Development: Develop and validate robust structural solutions to meet demanding customer requirements and military environmental specifications (e.g., MIL-STD-810). SME Analysis & Review: Act as the Structural Engineering Subject Matter Expert (SME) and reviewer; perform high-level complex stress, modal, and shock analyses and present results effectively to program leadership and customers. Project Integration: Collaborate across disciplines to ensure that structural constraints are balanced with thermal and electrical requirements, and that technical risks are fully understood and mitigated. Business Initiative Driver: Promote and implement strategic initiatives, including advanced simulation workflows, standardized structural reporting, and rigorous peer review processes for analysis reports. Team Mentorship: Lead and mentor a team of engineers, guiding them in the application of structural analysis best practices and developing their skills to advance into future technical leadership roles. Detailed Execution: Generate and assess complex FEA models, perform hand calculations for verification, conduct tolerance stack-up analyses, and define test parameters for structural verification efforts.
