We are looking for a contract Model-Based Design Engineer II to help lay the foundation for a DO-331 model-based development and verification process.\nYou will trace requirements to our control system models, build out an automated mission-level simulation test framework and its test suite, add unit tests, and automate coverage reporting and enforcement in our CI/CD pipeline. You will work closely with the GNC engineers who own the control laws, state machines, and estimators, and with the systems engineers who own the requirements.\nThe ideal candidate has hands-on experience with the MathWorks verification toolchain on safety-critical aerospace software, and understands control systems well enough to write meaningful tests for them. This is a fully remote contract position.\nResponsibilities\nRequirements Traceability\nTrace requirements from Jama to control system models, such as control laws, state machines, and estimators, using Requirements Toolbox.\nLink requirements to tests so traceability and requirements-based test coverage can be reported automatically and used for change impact analysis.\nFlag gaps and ambiguities found while tracing and resolve them with the requirement owners.\nMission-Level Simulation Testing\nBuild out our automated model-in-the-loop (MIL) integration test framework, which simulates complete flight missions and checks the results against requirements.\nDevelop the test suite on that framework, turning the simulations engineers already run during development into repeatable, automated tests.\nDocument the testing workflow and train the team to use it.\nUnit Testing & Coverage\nDevelop Simulink Test and MATLAB unit tests for control core models and functions, working toward full structural coverage.\nAutomate model and code coverage reporting, and add coverage enforcement to the CI/CD pipeline.\nInvestigate and help close coverage gaps, including differences between model and code coverage and logic that cannot be exercised.\nModel Quality & CI/CD\nHelp resolve Simulink Check findings against modeling guidelines, such as the MAB and high-integrity guidelines, so the checks can be enforced in the CI/CD pipeline.\nImprove our GitLab CI/CD pipelines for model-based development, including regression baselines, code generation, and automated reports.\nContribute to the modeling guidelines and process documentation that support DO-331 objectives.\nEducation\nBachelor’s degree in Aerospace, Mechanical, Electrical, or Computer Engineering, or a related technical field.\nExperience\n2+ years of industry experience in model-based design, verification, or GNC software development, or a Master’s degree with relevant research.\nHands-on experience with MATLAB, Simulink, and Stateflow.\nExperience writing requirements-based tests using Simulink Test or the MATLAB unit test framework.\nExperience collecting and analyzing model or code coverage, such as decision, condition, and MC/DC coverage with Simulink Coverage.\nExperience with requirements traceability using tools such as Requirements Toolbox, Jama, or DOORS.\nWorking understanding of control systems and state machines, enough to read control law models and write meaningful tests for them.\nProficiency in MATLAB scripting and Python for test automation.\nExperience with Git and CI/CD pipelines, such as GitLab CI or GitHub Actions.\nStrong written communication and documentation skills, and the ability to work independently on a remote team.\nPreferred Qualifications\nExperience developing or verifying software under DO-178C and DO-331.\nExperience with Simulink Check and Model Advisor, including writing custom Model Advisor checks.\nExperience integrating Jama with Requirements Toolbox, for example through OSLC.\nExperience with Embedded Coder code generation, software-in-the-loop testing, and MISRA C compliance or Polyspace.\nExperience with Simulink Design Verifier for test generation or property proving.\nExperience automating MATLAB toolchain workflows with Simulink Projects and the Project API.\nExperience with flight control or GNC software for aircraft, UAVs, or eVTOL platforms.\nExperience with agile development workflows and tools such as Jira and Confluence.\nExperience using AI-assisted development tools, such as Claude, to speed up test development, coding, and documentation.\nInterest in aviation, RC aircraft, or drones.\nAttributes aligned with Core Values\nSafety Above All: Demonstrates a proactive safety mindset by embedding safety into daily work, identifying and mitigating risks, encouraging open dialogue about safety concerns, and continuously improving practices and protocols.\nCustomer Focus: Puts customers at the center of every action by understanding their challenges, delivering meaningful value, and supporting their success.\nWork Better Together: Seeks and values diverse perspectives, builds cross-functional relationships, and fosters trust through empathetic, fact-based communication and commitment to shared decisions.\nBe the Pilot: Drives results with clarity and purpose by focusing on what matters most, adapting to change, taking initiative, and owning outcomes.\nEmbrace the Unknown: Navigates ambiguity with resilience and bold thinking, challenges the status quo, and combines innovative ideas with practical approaches to overcome obstacles and drive progress.\nRespect for People: Fosters a high-performance culture grounded in respect, professionalism, and support by balancing high expectations with a healthy, collaborative environment and being a trusted, dependable teammate.","description_format":"text","description_chars":5720,"description_truncated":false,"requirements":{"experience_years_min":2,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Military
