About the Role
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!
About Portal
From our Bothell, WA headquarters, we design vehicles with the maneuverability, resilience, and adaptability needed for the next era of orbital operations. Every system we build is in service of a simple idea: space should be more accessible, responsive, and capable.
Joining Portal means stepping into a team that believes in bold engineering, fast iteration, and the power of small groups to change what’s possible. If you want your work to directly shape the future of in-space mobility, join us.
