  • Analysis & Reporting: Analyze test results, identify, document, and track software defects and issues, and collaborate with development teams to ensure timely resolution
  • HIL System Management: Maintain and update HIL test setups and tools (e.g., dSPACE, Vector CANoe, MATLAB/Simulink) to ensure they accurately simulate real-world vehicle conditions
  • Cross-Functional Collaboration: Partner with software, hardware, and controls engineers to understand system requirements and ensure testability from the initial design phase

Requirements

  • Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field
  • 8+ years of experience in software testing, with a focus on embedded systems and HIL testing, preferably within the automotive or aerospace industry
  • Hands-on experience with HIL test environments such as dSPACE, Vector, or National Instruments
  • Strong proficiency in scripting languages like Python for test automation
  • Experience with MATLAB/Simulink for system modeling and control algorithm development
  • Familiarity with automotive communication protocols like CAN, LIN, and Ethernet
  • A solid understanding of Vehicle Control Units and their role in managing powertrain, chassis, and other vehicle systems
  • Excellent analytical and problem-solving abilities with a meticulous attention to detail
  • Strong communication and collaboration skills to work effectively with multidisciplinary teams
  • Ability to work independently in a fast-paced, agile environment
