Job description

We are seeking an experienced Systems Engineer 3 – Requirements, Validation & Verification to support the development and delivery of Human Machine Interface (HMI) display solutions for Energy & Transportation applications.

The ideal candidate will have strong experience in requirements engineering, system validation, verification, and embedded systems. This role involves translating customer and system-level needs into clear technical requirements, developing test strategies, executing validation activities, troubleshooting system issues, and ensuring product quality.

This is primarily a Systems Engineering and Validation & Verification role, rather than a traditional software development position.

Key Responsibilities

• Gather, analyze, develop, document, and maintain system and software requirements.
• Translate customer and system-level needs into clear, measurable, and testable requirements.
• Collaborate with software developers, systems engineers, and UI/UX teams to define HMI functionality and system interfaces.
• Develop and execute validation and verification strategies, test plans, and test cases.
• Perform functional, regression, sanity, endurance, and performance testing of embedded systems and HMI applications.
• Verify that implemented functionalities meet documented requirements and expected system behavior.
• Develop automated test scripts using Python or similar scripting languages.
• Perform system integration testing and troubleshoot complex hardware and software issues.
• Set up, configure, and maintain validation benches and test equipment.
• Maintain test documentation, validation evidence, and requirements-to-test traceability.
• Participate in Failure Mode and Effects Analysis (FMEA) and support risk mitigation activities.
• Apply Built-In Quality (BIQ) principles to improve product quality and reliability.
• Support software release validation, defect investigation, and customer issue resolution.
• Participate in design reviews, technical discussions, NPI, and continuous improvement activities.
• Collaborate with cross-functional and global engineering teams to ensure successful product development.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, Software Engineering, Computer Science, or a related technical discipline.
• 5-7 years of relevant engineering experience.
• Experience developing, documenting, reviewing, or managing technical requirements.
• Hands-on experience with software or system validation and verification.
• Experience developing and executing test plans and test cases.
• Experience validating embedded systems, HMI applications, controls, or electronic systems.
• Familiarity with software development and testing processes.
• Experience troubleshooting complex system and software issues.Familiarity with test automation and Python scripting.
• Understanding of embedded software algorithms, controls, and electronic systems.
• Strong technical documentation, analytical, and problem-solving skills.

Education and Experience Flexibility:

• Associate degree with 9 years of relevant experience.
• Master's degree with 3 years of relevant experience.
• Internships will not be considered as professional work experience.

Preferred Qualifications

• Experience with Human Machine Interface (HMI) or embedded display systems.
• Knowledge of requirements-to-test traceability and verification processes.
• Experience with Python-based test automation.
• Familiarity with Linux operating systems, including Ubuntu or Debian.
• Experience with communication protocols such as J1939, Caterpillar Data Link (CDL), and Modbus.
• Familiarity with diagnostic and validation tools such as CAT ET, CANalyzer, CANape, CADET, or ModSim.
• Experience with FMEA and structured risk-management processes.
• Knowledge of Change Request Management (CRM), New Product Introduction (NPI), and Continuous Product/Process Improvement (CPI).
• Experience working with distributed engineering teams and external suppliers.
