Lion Energy is seeking a Model Based Controls Engineer to support development of advanced control systems for next-generation energy storage and portable power solutions. This role focuses on independently developing control models, algorithms, and simulation environments while contributing to system-level product development. Engineers in this role demonstrate strong technical proficiency, collaborate across disciplines, and help ensure high-performance and reliable control system implementations.

• Independently design, develop, and implement control systems for energy storage and power conversion products
• Develop and maintain plant models for energy storage systems using MATLAB, Simulink, and Simscape
• Design and simulate control algorithms supporting:
  • DC-DC and DC-AC conversion
  • Maximum Power Point Tracking (MPPT)
  • Battery charge management and protection
  • Energy management and system-level power coordination
• Perform simulation and validation of control algorithms using plant models and system simulations
• Generate production-ready control algorithm source code using model-based design workflows
• Collaborate with embedded software engineers to integrate generated code into hardware platforms and BSP layers
• Participate actively in system architecture discussions, design reviews, and code reviews
• Understand system-level interactions, integration constraints, and performance trade-offs
• Identify, debug, and resolve moderately complex modeling and control system issues
• Partner with validation teams to define test procedures and verification strategies
• Document models, algorithms, and technical decisions supporting development and validation efforts

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field
• Typically 2–5 years of controls engineering or model-based design experience
• Strong proficiency in MATLAB, Simulink, and Simscape
• Experience designing and validating control algorithms using simulation and model-based development workflows
• Working knowledge of embedded system integration principles
• Familiarity with LabVIEW or other test automation tools preferred
• Understanding of energy storage and power electronics systems is a plus, including:
  • MPPT
  • DC-DC converters
  • Inverters
  • Battery management and energy management systems
• Familiarity with Model-Based Systems Engineering (MBSE) concepts and SysML is a plus
• Strong analytical, problem-solving, and troubleshooting skills
• Experience developing validation procedures and test plans preferred
• Deliver control models and algorithm features with minimal supervision
• Demonstrate growing system-level understanding of energy storage and power conversion
• Improve control system performance, reliability, and maintainability
• Expand subsystem ownership and technical influence over time
