Structural Analysis Engineer II/III

Opterus is an innovative aerospace company based in Loveland, Colorado, specializing in deployable space structures and high strain composite systems. We combine cutting-edge composite materials, elastic origami architectures, and elegant engineering to deliver lightweight, high-performance structural systems for commercial, defense, and scientific missions.

Opterus’ Structural Analysis Engineer II/III will shape system-level architecture while developing robust, scalable analytical solutions. You will collaborate cross-functionally with mechanical, manufacturing, and program management groups to define structural requirements, influence early design decisions, and ensure performance and reliability through rigorous analysis and verification. In this role, you will work to solve complex technical problems relating to the development of next generation deployable structures leveraging cutting edge composite technologies. Success in this role will require deep understanding of structural theory and advanced Finite Element Analysis (FEA) techniques. Experience with deployable systems such as booms, RF antennas, and solar arrays is strongly preferred.
