Control Engineer

Controls Engineer – Model-Based Design (HVAC)Location: Kennesaw, GA (Onsite)Job DescriptionThis role focuses on designing, developing, and validating advanced control systems and embedded software for commercial and residential HVAC applications using model-based design methodologies. You will collaborate closely with cross-functional engineering and test teams to create robust control algorithms, define and trace requirements, and build automated verification workflows that ensure high-quality control software throughout the product lifecycle.ResponsibilitiesDesign, develop, verify, and validate control systems and embedded software solutions for HVAC products using model-based design techniques.Develop controls-oriented models in MATLAB, Simulink, Stateflow, and Simscape to implement control and diagnostic strategies that meet performance requirements and system constraints.Select appropriate control and diagnostic strategies for system features based on system-level requirements, performance targets, and operating constraints.Analyze and interpret high-level system requirements and existing functional implementations in C/C++ codebases to guide model and software design.Create feature-specific model content, including model properties, input/output interfaces, and architecture design that align with system requirements.Validate developed models using tools such as Model Viewer, Advisor Checks, and Code Coverage analysis to ensure quality and compliance.Ensure all models and implementations comply with MAAB (MathWorks Automotive Advisory Board) modeling guidelines and best practices.Collaborate with multidisciplinary engineering teams to define and refine system and software requirements, ensuring they are properly scoped, testable, and traceable.Work closely with feature owners and stakeholders to clarify functional requirements and design intent, and maintain end-to-end requirement traceability using model-based development and verification tools.Develop test plans, test cases, and automated test scripts based on system and software requirements for model-based verification and validation.Perform Model-in-the-Loop, unit, functional, and integration testing to verify model and software behavior and ensure adequate test coverage.Generate and review test coverage reports to confirm sufficient verification of developed models and embedded control software.Utilize test automation tools such as MATLAB Unit Test, Simulink Test, Requirements Management Interface (RMI), or equivalent frameworks to streamline verification workflows.Support integration of modeled controls with handwritten C/C++ code and validate execution on embedded target hardware.Collaborate with controls, software, systems, validation, and product engineering teams to align design, implementation, and testing activities.Participate in Agile development activities, including planning, reviews, and continuous improvement initiatives, to enhance development processes and team effectiveness.Contribute to the development and refinement of automated verification workflows and testing infrastructure to improve efficiency and consistency.Support root cause analysis, debugging, and resolution of control software issues discovered during development, testing, or deployment.Apply strong analytical and problem-solving skills to diagnose complex control and software issues and propose effective solutions.Communicate clearly with cross-functional and customer-facing teams to explain design decisions, test results, and issue resolutions.Essential SkillsBachelor’s degree in Electrical Engineering, Computer Engineering, Electronics Engineering, Computer Science, or a related field with 5+ years of experience, or a Master’s degree in Electrical Engineering, Computer Science, or a related field with 3+ years of relevant experience.Minimum 3+ years of model-based software development experience using MATLAB and Simulink.Minimum 2+ years of controls software design and development experience.Strong experience with MATLAB, Simulink, Stateflow, Simscape, and model-based design methodologies.Working knowledge of embedded software development principles and practices.Understanding and hands-on experience with C/C++ programming and code integration into embedded systems.Experience with modeling, simulation, and testing techniques in Simulink, including configuration for auto-code generation.Familiarity with auto-code generation and modeling practices that affect software efficiency, memory usage, and code size.Experience using version control systems such as Git, GitHub, or ClearCase for managing source code and models.Experience developing and executing automated testing frameworks and verification workflows.Ability to interpret system and software requirements and translate them into comprehensive test cases and validation strategies.Experience generating and reviewing test coverage reports for control software and model-based implementations.Strong analytical and problem-solving skills with a detail-oriented and quality-focused mindset.Excellent verbal and written communication skills, with the ability to work effectively in cross-functional and customer-facing environments.Self-motivated and proactive approach to learning, problem solving, and continuous improvement.Additional Skills & QualificationsControls theory experience and strong understanding of control system concepts.Knowledge of HVAC control systems and prior experience working with HVAC controls or similar systems.Experience with Model-in-the-Loop (MIL), Software-in-the-Loop (SIL), or Hardware-in-the-Loop (HIL) testing environments.Experience with Python scripting for automation and testing of models and embedded software.Familiarity with requirements management and traceability tools for maintaining end-to-end linkage between requirements, models, and tests.Agile or Scrum development experience, including participation in planning, reviews, and continuous improvement activities.Experience contributing to or developing automated verification workflows and testing infrastructure.Demonstrated ability to support root cause analysis and debugging of control software issues across the development lifecycle.
