Cimarron is seeking a Senior Avionics System Engineer to support our partnership with a commercial aerospace company at their rocket production facility in Cedar Park, TX.

Through this partnership, Cimarron supplies skilled technical talent in support of our customer's advanced launch and space systems. This customer designs and builds small- to medium-lift launch vehicles, lunar landers, and orbital vehicles for government and commercial missions from low Earth orbit to the Moon and beyond. Together, our teams leverage advanced carbon composite structures, patented propulsion technologies, and common components across platforms to move fast, improve reliability, and deliver payloads at a lower cost.

• Own the entire process of designing the electrical architecture, testing and integrating avionics components onto the spacecraft.
• Support assembly, integration, and test (AIT), launch integration, and on-orbit operations.
• Intuitively understand the intention behind design decisions, and direct assembly and test operations based on those intentions.
• Write and execute vehicle assembly procedures and electrical system functional validation processes.
• Lead high-level, functional design and development of avionics systems for the current and future spacecraft.
• Develop design verification, qualification, and acceptance test plans, and coordinate with the other avionics and manufacturing engineers and technicians to execute.
• Recommend spacecraft function and reliability upgrades based on experience.
• Requirement writing and verification for spacecraft avionics.
• Develop new features and functionality as part of the design team for our common avionics platform used across launch vehicles and spacecraft applications.
• Participate in technical trade studies, requirement capture, conceptual and detail design activities for new and existing designs.
• Create and own schematic capture and PCB layout activities, rapid prototyping, EEE component selection, and execute electrical simulations and analyses to support flight, qualification, and test lab PCB assemblies.
• Work with experts across teams and departments (systems, mechanical, software, test engineering) to develop tightly integrated, high-performance hardware.
• Understand and implement aerospace guidelines for development and design of electronic assemblies.

• Due to facility security requirements, only U.S. citizens or permanent residents are eligible for consideration at this time.
• 7 or more years of experience working with aerospace component development, testing, integration, or operations.
• 5 or more years of experience in electrical engineering in both analog and digital circuit design, including usage of test equipment such as logic analyzers, oscilloscopes, signal generators, electronic loads, multimeters, and interpreting electrical schematics.
• Experience performing trade studies and sensitivity studies to select the best architecture option.
• 3 or more years of hands‑on experience with prototyping circuits and testing.
• 5 or more years of PCB design, hardware systems design, and/or integration experience.
• Skilled in schematic capture and digital, analog, and power circuit PCB layout.
• Competent at end‑to‑end definition, requirement generation, block‑diagram design, component selection and circuit simulations.
• Strong electrical troubleshooting experience with…
