Materials & Composites Build Engineer

We are seeking an engineer to be responsible for the development and delivery of non‑metallic solutions across the Portal vehicle family, focusing primarily on lightweight and deployable mirror structures for the Supernova vehicle. This role works in concert with design and mission engineers to develop a structure, manufacturing process, and test regime for delivering high‑precision composite surfaces for current and future spacecraft missions.

Join us in developing simple, scalable solutions that bring high‑mobility spacecraft to orbit!

• Develop composite mirror architecture and sub‑assemblies in partnership with designers and external partners
• Select and manage partner vendors to develop demo units and prepare for production scaling
• Own and simplify non‑metallic polymers, bonds, and materials across multiple vehicles
• Develop qualification and production test processes for primary and secondary non‑metallic structures

• 4+ years of experience developing and testing composite structures, or similarly process‑intensive assemblies in an engineering capacity
• Experience steering the development and qualification of composite spacecraft structures
• Direct experience working with suppliers or external partners to develop and deliver on complex composites needs
• Hands‑on support of hardware qualification, integration, or development testing to meet aerospace standards (SMC‑S‑016 or similar specifications)

• Deep knowledge of polymers, coatings, and processes as applicable to spacecraft and the space environment
• Functional proficiency with NX (or similar CAD), as well as manufacturing planning and execution programs
• Proven ability to communicate technical concepts clearly across engineering disciplines and external suppliers
