Quest Defense Systems & Solutions is seeking a MATLAB / Simulink Design and Process Software Engineer with strong model-based development experience to support real-time engine control and aerospace systems.

This role centers on the design, development, and integration of Simulink models and auto-generated code within embedded architectures, with a focus on safety-critical applications (DO-178C environments). The team is also driving a transition from SCADE to Simulink, requiring engineers who can both execute technically and provide guidance on model development, code generation, and system integration across multiple programs.

Due to the nature of this role, all candidates must be U.S. citizens.

This role is remote with the possibility of some travel to Cincinnati, OH.

Key Responsibilities:

• Design, develop, and implement MATLAB Simulink models for engine control systems, ensuring robust model-based software development that meets customer requirements.
• Generate production-ready code from Simulink models, integrating seamlessly with customer-specific architectures for real-time engine control applications.
• Lead technical reviews and validation of Simulink models to ensure compliance with industry standards, such as DO-178C, for safety-critical systems.
• Collaborate with cross-functional teams, including systems engineers and hardware teams, to ensure compatibility and performance of integrated control systems.
• Develop and execute test plans for model verification and validation, utilizing automated testing tools and simulation environments.
• Provide technical leadership, guiding customer teams on best practices for MATLAB Simulink usage, including model development, debugging, and optimization.
• Assist the customer in transitioning from using SCADE to Simulink as their model-based software development tool. Train customer personnel through hands-on workshops and documentation, enabling effective adoption and maintenance of Simulink-based workflows.
• Troubleshoot and resolve complex issues in Simulink models, code generation, and system integration, ensuring high reliability and performance.

Required Skills & Qualifications:

• Bachelor’s degree in computer science, electrical engineering, or related field.
• 5+ years of experience in MATLAB Simulink model-based development, specifically for engine control or aerospace systems.
• Proven experience in code generation from Simulink models and integration with embedded systems.
• Strong understanding of control system design principles and real-time software architectures.
• Experience with DO-178C or similar safety-critical software development standards.
• Demonstrated ability to lead projects and train technical teams, with excellent communication and interpersonal skills.
• Proficiency in related tools such as MATLAB, Stateflow, and embedded C/C++ programming.
• Familiarity with version control systems (e.g., Git) and Agile development methodologies.
• U.S. citizenship required.

Preferred Qualifications:

• Experience supporting or leading a transition from SCADE to MATLAB/Simulink in a model-based development environment
• Prior experience developing or integrating engine control systems, FADEC, or similar aerospace control applications
• Familiarity with auto-code generation workflows using Simulink (e.g., Embedded Coder) and downstream integration into embedded targets
• Experience working in DO-178C Level A or B environments, including involvement in certification artifacts and audits
• Exposure to hardware/software integration, including working with real-time targets and lab environments (HIL/SIL)
• Experience with requirements-based development and traceability using tools such as IBM DOORS or similar
• Familiarity with configuration management and version control tools (e.g., Git, Bitbucket) in a collaborative development environment
• Prior experience mentoring or training engineers on model-based development tools and best practices
• Exposure to Stateflow for complex logic modeling within Simulink
• Experience in the adoption and/or integration of emerging technologies (e.g., generative AI, automation platforms, digital assistants) into day-to-day operations for continuous improvement.
