Job description

Job description

Test Automation Engineer is responsible to develop, and execute automated test frameworks for environments like SIL(Software-in-the-loop) and HIL(Hardware-in-the-loop), that allow us to test our power plant controller and SCADA system. Your mission is to build the automated frameworks that catch edge cases before they hit the field, ensuring every product we ship meets the highest standards of reliability.

Responsibilities

• Automation Framework Development: Design, build, and maintain scalable automated test frameworks and scripts for power, control and SCADA systems using Python. You will transition our validation processes from manual intervention to a fully automated, scalable framework.
• V&V Strategy: Define and execute comprehensive Verification and Validation (V&V) plans, ensuring all software requirements for the site controller and SCADA systems are met under normal and fault conditions
• CI/CD Integration: Integrate automated HIL/SIL testing into our CI/CD pipelines, providing real-time feedback to the development teams and serving as the final gate for production-ready code
• Requirements Investigation: Analyze and interpret technical specifications to author comprehensive automated test suites, actively tracking down gaps in system requirements.
• Multi-Environment Execution: Execute automated test suites across SIL, MIL, and HIL setups. Analyze test captures, isolate system failures, and generate detailed engineering reports.
• Root Cause Analysis: Work closely with the controls and systems teams to debug complex failures found during validation, using logic analyzers, oscilloscopes, and telemetry logs to pinpoint issues

Qualifications

• Education: Bachelor’s or master’s degree in electrical engineering, Computer Engineering, Computer Science, or a related field.
• Experience: 2+ years of professional experience in software validation or test automation for hardware-focused systems.
• Programming Mastery: Expert-level proficiency in Python and Bash scripting, alongside a practical reading knowledge of PLC/RTAC/IEC 61131-3 Control logic.
• Automation Toolchains: Direct experience architecting or heavily extending modern pythonic test frameworks (such as Pytest or OpenHTF).
• Systematic Thinking: A dedicated mindset for “breaking” software. You have a track record of finding critical edge cases in complex state machines and control loops
• Infrastructure: Experience with Git, Jenkins/GitHub Actions, and containerization tools like Docker for managing consistent test environments

Preferred Qualifications

• Knowledge of NERC, FERC, ISO/RTO, and utility interconnection requirements is preferred.
• Experience with utility-scale solar PV, Battery —Energy Storage Systems (BESS), hybrid renewable energy plants, or inverter-based resources (IBR) is preferred.
• Version Control: Advance user-level with Git and modern branch management strategies.
• Communication protocols (e.g., IEC 61850, Modbus, DNP3)

Compensation And Benefits

Our salary ranges are determined by role, level, and location. This role offers a base salary of $80,000 – $100,000. Within each posted range, individual pay is determined (and may be greater or higher), dependent on work location and additional factors, including job-related skills, experience, and relevant education or training.
