Spacecraft Structures Engineer

Overview Energy is a mission-driven team committed to delivering Space Solar Energy to the world. We operate at the intersection of space infrastructure and energy abundance, providing baseload power across entire continents 24/7, without seasonality or the need for batteries. Headquartered in the Washington, DC area and backed by world-class investors, we are advancing the next generation of clean energy technology.

Overview Energy's Structures Engineer leads the design, structural analysis, testing, and manufacturing of spacecraft structural systems from concept through integration and flight. The role blends hands‑on engineering with technical leadership, driving the creation and implementation of structural assemblies, components, and integrated systems. The ideal candidate brings proven expertise in spacecraft structures including both analytical and hands‑on capabilities, and thrives in a fast‑paced, multidisciplinary environment.

• Lead end‑to‑end development, analysis, prototyping, and integration of structural systems and spacecraft components for advanced space systems, collaborating closely within a cross‑functional engineering team

• Perform comprehensive structural analysis of spacecraft and platform components, including composites and metallic structures, using advanced analytical methods and industry‑standard software (NX Nastran, FEA tools)

• Develop, refine, and validate finite element models to assess structural performance under static, dynamic, thermal, and acoustic loads; perform trade studies and mass optimization analyses

• Develop allowables and assess structural margins for bolted and bonded joints

• Design and model parts, assemblies, and components in CAD software (NX), ensuring manufacturability, ease of assembly, and complete product definition including drawings, GD&T specifications, and test procedures

• Apply design‑for‑manufacturing (DFM) principles and rapid prototyping techniques to optimize spacecraft structural designs for simplicity, reduced cost, and efficient production

• Lead and support structural test campaigns including design, execution, data processing, and validation, documenting results and lessons learned

• Bachelor's degree in Mechanical, Aerospace, Structural Engineering, or equivalent hands‑on experience in a mechanical/aerospace engineering role

• Minimum of 5–7 years of progressive experience in mechanical design, analysis, and testing

• Strong proficiency with 3D CAD software (NX preferred) and advanced FEA tools (NX Nastran or equivalent)

• Experience in spacecraft‑level structural test campaign design, execution, data processing, and validation

• Solid understanding of GD&T, design‑for‑manufacturing (DFM) principles, and mechanical design best practices

• Strong understanding of dynamic mechanical system design, analysis, and failure modes (modal, random vibration, buckling, thermoelastic analysis)

• Demonstrated experience with structural analysis of both metallic and composite structures (laminate design, joint design, materials characterization)

• Experience with rapid prototyping and hands‑on mechanical assembly

• Proven ability to own and deliver complex structural systems from concept through final implementation

• U.S. citizenship required

• Experience with satellite or spacecraft primary and secondary structures in flight programs

• Familiarity with composite manufacturing processes and design‑to‑cost approaches for space hardware

• Experience with thermal‑structural analysis and distortion modeling
