Control Engineer

Controls Engineer – Model-Based Design (HVAC)

Job Description

This 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.

Responsibilities

• Design, 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 (Math Works 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.
• Bachelor’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…
