Electronic Systems Design and Analysis Engineer (Mission Computing)

Join to apply for the Electronic Systems Design and Analysis Engineer (Mission Computing) role at Cimarron Inc.

Position Introduction & Key Duties

Cimarron is seeking senior-level Electronic Systems Design and Analysis Engineers to support an advanced aerospace development effort for the Phantom Works program in St. Charles, MO. This innovative program focuses on next‑generation technologies for defense and flight systems.

• Lead the development, documentation, and maintenance of avionics architectures, requirements, algorithms, interfaces, and designs.
• Serve as a subject matter expert for system‑level architecture, system‑specific issues, and related engineering processes.
• Lead the implementation of Open Mission Systems (OMS) and Model‑Based Systems Engineering (MBSE) tools and processes across the engineering team.
• Collaborate with specialty engineering teams to decompose requirements to the mission computer, ensuring performance, safety, and environmental requirements are clearly defined and implemented.
• Coordinate with internal and external stakeholders to execute hardware‑software integration activities in a fast‑paced Agile environment.
• Work with customers and aircrew to develop and document complex electronic and electrical system requirements.
• Analyze customer requests to assess contractual and technical impacts and translate them into actionable system requirements.
• Provide technical leadership in evaluating emerging technologies, performing technical planning, and integrating new technology solutions.
• Support technology demonstrations to advance system capabilities and program objectives.
• Resolve product integration issues and production anomalies throughout the development and sustainment phases.
• Identify and resolve issues related to fielded hardware and software across the product lifecycle.

• Due to facility security requirements, only U.S. citizens are eligible for consideration at this time.
• Ability to obtain a Secret Clearance in a reasonable timeframe.
• Ability to obtain Special Program Access or other government access requirements, if needed.
• 20 or more years of related experience.
• Experience developing and integrating Open Mission Systems (OMS) architectures and solutions.
• Experience with Model‑Based Systems Engineering (MBSE) development and implementation.
• Familiarity with the Universal Command and Control Interface (UCI) message standard and Common Abstraction Layer (CAL).
• Experience with system design and development, including component interactions, interfaces, and overall system functionality.
• Experience with requirements development and management, including creation of technical performance specifications and statements of work.
• Bachelor of Science from an accredited course of study in Engineering, Chemistry, Physics, Mathematics, Data Science, or Computer Science.

• Experience with NSA Command and Control (C2) and NCDSMO interactions and certification processes.
• Experience working with multi‑level security (MLS) networks.
• Experience developing and integrating multi‑level security embedded systems.
• Experience with cryptographic units and cross‑domain solutions/guards, including access and transfer CDS.
• Knowledge of 3U and 6U VPX/OpenVPX architectures, including VITA 46 and VITA 65 standards, with an understanding of trade‑offs related to size, weight, power (SWaP), processing capability, and I/O density.
• Knowledge of signal integrity and interconnect principles, including high‑speed digital signal design, impedance matching, and advanced interconnect solutions such as VPX3 discrete coaxial/twinax cabling.
• Experience with high‑performance embedded computing (HPEC) and performance optimization within 3U and 6U form factors.
• Experience with hardware design and development across all phases of the product lifecycle, from initial concept through flight maturity.
• Experience with hardware‑in‑the‑loop (HIL) simulations and testing methodologies to verify system functionality.
• Experience designing secure architectures, implementing cryptographic…
