Cimarron Inc. Tech Stack

Defense and space mission-critical software and systems engineering

Defense and Space Manufacturing Houston, Texas 201–500 employees Founded 1981 Privately Held

Cimarron is a 201–500-person defense and aerospace contractor headquartered in Houston, deeply embedded in NASA programs and commercial space ventures. The tech stack is heavily weighted toward embedded systems and real-time control (MATLAB, Simulink, C/C++, VHDL, ModelSim, DO-178C certification tooling) with infrastructure backbone (AWS, IBM DOORS, JAMA). The hiring mix is 80% senior engineers relative to mid/junior, and active projects span ground systems architecture, autonomous vehicle development, and commercial space station software — a profile consistent with mission-critical, regulated work where experience density matters more than headcount growth.
