Senior Mechanical Engineer, Stress Analysis

Senior Mechanical Engineer, Stress AnalysisWe're looking for a structures engineer with strong design and analysis fundamentals, someone eager to learn and flexible enough to take on whatever a fast-moving hardware program throws at them. You'll work in an exciting, fast-paced environment tackling some of the most challenging structural problems in aerospace.ResponsibilitiesPerform structural analysis (static, buckling, and modal) on airframe, gondola, and equipment mount structures using FEA tools (FEMAP/NX Nastran or equivalent)Develop and maintain finite element models, including mesh generation, load case setup, and post-processing of resultsPerform hand calculations to size structures, verify FEA results, and support quick-turn design tradesSize and design structural components and assemblies, from concept sketches through detailed CADCorrelate analytical models against test data (static load tests, modal surveys, ground vibration testing)Support design trade studies weighing weight, strength, manufacturability, and costDocument analysis methodology, assumptions, and results in formal engineering reportsCollaborate with Systems, Avionics, Soft Structures, Materials & Testing, and Manufacturing teams to integrate structural designs with the broader vehicleSupport fabrication, assembly, and test of structural prototypes and hardwareInvestigate and resolve structural issues found during build, test, or field operationsPerform joint analysis (bolted, bonded, and welded) to size fasteners, adhesives, and welds and substantiate joint marginsQualificationsBachelor's degree in Mechanical Engineering, Aerospace Engineering, or a closely related field5+ years of relevant experience in structural design and/or analysisHands-on experience with FEA software (e.g., FEMAP, Nastran, ANSYS, or similar)Highly developed knowledge of structural analysis fundamentals: static strength, buckling, and modal/dynamic analysisProficiency with 3D CAD (SolidWorks, NX, or similar)Experience with joint analysis (bolted, bonded, and/or welded joints)Scripting/programming experience (e.g., Python, MATLAB, or VBA) to automate analysis and modeling workflowsMust be able to work on-site in Sunnyvale, CaliforniaPreferred QualificationsExperience with lighter-than-air, aerospace, or other weight-critical vehicle structuresExperience correlating FEA models to physical test dataFamiliarity with composite structures (CFRP) design and analysisExperience with structural dynamics (modal testing, vibration analysis)Experience with fatigue analysis and life predictionMaster's degree in Mechanical or Aerospace EngineeringExperience in a fast-paced startup or low-volume prototype development environmentFamiliarity with GD&T and manufacturing drawing standardsWhat We Offer!Relocation assistanceExcellent medical, dental, and vision insurance through a PPO plan (100% premium paid for individuals, ~70% for dependents)Company-paid life, AD&D, long-term disability, and short-term disability insurancesParental leaveGenerous PTO + 10 paid holidays401(k) matching up to 6%Lunch and snacks provided every day, including accommodations for all dietary restrictionsMonthly wellness stipendMonthly cell phone stipendYearly education stipend to obtain certifications or take classes in your fieldFun events, swag, and the occasional airship rideAn opportunity to change the world and work with some of the smartest and the most talented experts from different fieldsCompliance RequirementsCriminal background check clearanceDrug test clearance wherever applicableApplicant must be able to obtain a NASA Moffett Federal Airfield AOA Badge
