Senior Mechanical Engineer (Stress Analysis)

Join Zipline, a pioneering company in the logistics industry. As a Senior Mechanical Engineer specializing in stress analysis, you will be responsible for aircraft structural analysis, global finite element models, and detailed finite element models. Your work will directly impact aircraft airworthiness, fleet uptime, and mission success. You will collaborate with various teams and have the opportunity to support flight tests and field remediation events. The role is based in South San Francisco and requires a minimum of 5 years of experience in structural analysis for aircraft or complex aerospace vehicles.

• Assumer la responsabilité de l'analyse structurelle des aéronefs, en possédant les modèles de éléments finis globaux et détaillés.
• Effectuer des études d'analyse rapide et fournir des conseils en matière de conception, en réalisant des calculs manuels et en créant des modèles FEM légers.
• Diriger les enquêtes sur les échecs et les actions correctives, en générant des modifications de conception correctives et en travaillant avec les équipes de fabrication, de conception, de fiabilité et d'essai.
• Must be eligible to work in the US
• Must-have traits: clear owner mentality with rapid decision cadence, tolerance for ambiguity and shifting configurations, disciplined documentation habits, and the ability to identify opportunities to maximize impacts to cost, scalability, and fleet health
• Solid classical stress and dynamics background: Roark/Bruhn-level hand-calculation fluency plus structural modes, random vibration, and forced-harmonic analysis experience
• Deep capability with industry-standard tools (examples: NX, FEMAP/NX Nastran, ANSYS, Siemens Design Center), and proficiency scripting in Python or MATLAB to automate workflows and reports
• Location: role is based in South San Francisco
• Demonstrated ownership of a top-level GFEM or equivalent system-level model integrating multiple subsystem inputs; experience managing contributions from 3–5 engineers
• Minimum 5 years experience in structural analysis for aircraft or complex aerospace vehicles working with metallic, composite, and polymer structures; must have hands-on hardware experience
• Proven track record of experimental correlation: defining instrumentation, producing pre-test predictions, and tuning models to match static/dynamic/flight tests within engineering tolerances
