We’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.

Perform 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 results

Perform hand calculations to size structures, verify FEA results, and support quick-turn design trades

Size and design structural components and assemblies, from concept sketches through detailed CAD

Correlate analytical models against test data (static load tests, modal surveys, ground vibration testing)

Support design trade studies weighing weight, strength, manufacturability, and cost

Document analysis methodology, assumptions, and results in formal engineering reports

Collaborate with Systems, Avionics, Soft Structures, Materials & Testing, and Manufacturing teams to integrate structural designs with the broader vehicle

Support fabrication, assembly, and test of structural prototypes and hardware

Investigate and resolve structural issues found during build, test, or field operations

Perform joint analysis (bolted, bonded, and welded) to size fasteners, adhesives, and welds and substantiate joint margins

Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or a closely related field

5+ years of relevant experience in structural design and/or analysis

Hands-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 analysis

Proficiency 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 workflows

Must be able to work on-site in Sunnyvale, California

Experience with lighter-than-air, aerospace, or other weight-critical vehicle structures

Experience correlating FEA models to physical test data

Familiarity with composite structures (CFRP) design and analysis

Experience with structural dynamics (modal testing, vibration analysis)

Experience with fatigue analysis and life prediction

Master's degree in Mechanical or Aerospace Engineering

Experience in a fast-paced startup or low-volume prototype development environment

Familiarity with GD&T and manufacturing drawing standards
