Opportunity Summary

n

An ambitious early-stage startup is building modular, self-assembling structures for future space applications. Think scalable platforms, orbital infrastructure, and adaptable in-space systems. Backed by top-tier investors and operating in stealth, the company is seeking a hands-on Mechanical Engineer to take the lead on mechanical design for the next of electromagnetic structural systems.

n

This role blends analytical design, iterative prototyping, and field testing of mechanical assemblies that enable intelligent docking, structural interlocking, and thermal/power transfer across modular spacecraft components.

About Us

n

Were a venture-backed, stealth-mode aerospace startup developing autonomous, self-assembling hardware architectures designed for orbital and deep space environments. Our team includes alumni from leading space and hardware companies, and were focused on building scalable systems that unlock a new era of modularity in orbit. With funding secured and early prototypes already under development, were pushing forward at full speed.
