About the RoleApex is looking for a Lead Structures Engineer to support our current and next generation satellites. This person will own the design, development, and delivery of flight-critical spacecraft structural systems from concept through on-orbit operation. This role will drive architecture, analysis, hardware execution, and cross-functional integration for primary and secondary structures, load-bearing assemblies, and structural interfaces.
You will operate with high ownership, leading complex hardware programs while partnering closely with thermal, avionics, propulsion, mechanisms, and manufacturing teams to deliver reliable, production-ready systems at scale.
Responsibilities:- Own end-to-end design of spacecraft structural systems (primary structure, secondary structure, brackets, panels, and interfaces) from concept through flight, including architecture, requirements, CAD, drawings, and specifications
- Drive trade studies (mass, stiffness, strength, manufacturability, reliability), make-vs.-buy decisions, and supplier execution while partnering cross-functionally (thermal, propulsion, avionics, GNC, manufacturing) to deliver fully integrated systems
- Perform first-principles analysis and FEA (static, dynamic, modal, thermal distortion, and load path analysis) to size and validate spacecraft structural components and assemblies
- Develop and execute structural test plans (development, qualification, acceptance), including vibration, shock, thermal vacuum, and static load testing; analyze results and iterate designs based on data and flight feedback
- Own hardware through build, integration, and test, diagnosing issues quickly and driving solutions in fast-paced, hands-on environments
- Lead a small team through design reviews, set technical direction, and mentor engineers while driving decisions that balance performance, risk, schedule, and manufacturability
Requirements:- Bachelor's degree in Mechanical or Aerospace Engineering (or related field)
- 5+ years of experience designing and delivering structural or mechanical systems
- 1+ years of professional experience leadinging technical teams and/or projects
- Experience owning hardware from concept through test or production
- Strong fundamentals in structural analysis, mechanical design, and system integration
- Experience designing lightweight aerospace structures, load-bearing assemblies, composite or metallic structures, and structural interfaces
- Proficiency with CAD (NX, CATIA, SolidWorks) and FEA tools (ANSYS, Nastran, Abaqus, etc.)
- Experience developing and executing structural test campaigns
- Demonstrated ability to move quickly, take ownership, and solve complex problems in fast-paced environments
- Experience working with suppliers and managing external partners
- Exposure to spacecraft, launch vehicles, or other high-performance hardware systems
Nice to Have:- Experience with spacecraft or aerospace structural systems
- Familiarity with environmental testing (vibe, shock, thermal vacuum)
- Hands-on experience with machining, assembly, integration, or hardware bring-up
- Familiarity with composite design, bonded structures, or lightweighting strategies
- Scripting or analysis tools (Python, MATLAB, etc.)
