About The Position

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.

Requirements

Bachelor’s degree in Mechanical Engineering.
6+ years’ experience in mechanical/structural engineering.
Expert fundamentals of structural analysis, stress/strain, and fatigue documentation principles.
Mastery of state-of-the-art structural analysis software tools (e.g., ANSYS Mechanical, Nastran/Patran, Abaqus, MATLAB, etc.).
Knowledge of material properties for aerospace/defense applications and experience with the production and sustainment of structural mechanical systems.
Must be able to obtain a Secret Clearance.
Motivated self-starter and problem solver with proven experience executing in multi-disciplinary teams.
Strong written and verbal communication skills.
Ability to maintain a high-level strategic view of structural integrity while managing detailed simulation execution.

Responsibilities

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.
Hold primary responsibility and authority for structural analysis. Utilize advanced simulation techniques to predict failure modes, optimize weight, and ensure structural margins are maintained.
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.
Develop and validate robust structural solutions to meet demanding customer requirements and military environmental specifications (e.g., MIL-STD-810).
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.
Collaborate across disciplines to ensure that structural constraints are balanced with thermal and electrical requirements, and that technical risks are fully understood and mitigated.
Promote and implement strategic initiatives, including advanced simulation workflows, standardized structural reporting, and rigorous peer review processes for analysis reports.
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.
Generate and assess complex FEA models, perform hand calculations for verification, conduct tolerance stack-up analyses, and define test parameters for structural verification efforts.
