Defense and space mission-critical software and systems engineering
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.
Cimarron provides systems engineering, software development, and real-time command-and-control solutions for NASA, U.S. defense programs, and emerging commercial space operators. Founded in 1981, the company has supported human spaceflight since 1988, including work on the International Space Station, Space Shuttle, and NASA's Mission Control infrastructure. Current engagements include ground systems for commercial space stations, autonomous spaceplane development, and satellite ground system architecture. The company operates under defense and aerospace regulatory frameworks (DO-178C, configuration management via IBM DOORS and JAMA) and is actively hiring across engineering roles while addressing internal challenges around quality repeatability, fabrication efficiency, and meeting critical milestone delivery.
Cimarron's stack emphasizes real-time embedded systems: MATLAB and Simulink for modeling, C/C++ and VHDL for implementation, ModelSim and Vivado for simulation/verification, and DO-178C certification compliance tooling. AWS provides cloud infrastructure; IBM DOORS and JAMA manage requirements and configuration.
Active projects include Sentinel launch infrastructure integration, Axiom space commercial station software, X-37B autonomous spaceplane development, ground systems architecture for defense/communications, and satellite ground system modernization, alongside internal tooling and test procedure development.
