Job description

Job Profile Tasks/Responsibilities:

• Test Planning and Execution
• (We are considering candidates at different levels. A level IV candidate will develop tasks in this list and a level V candidate will lead tasks in this list).
• Lead development of detailed test procedures from system test plans, including step-by-step instructions, acceptance criteria, data collection requirements, and safety controls for complex or multi-system test activities.
• Lead execution of systematic testing of facility systems in accordance with approved procedures and disciplined Conduct of Operations practices, including verbatim compliance, peer checking, and three-way communication.
• Model and reinforce questioning attitude throughout testing by stopping work when conditions are not as expected, challenging assumptions, and resolving concerns when acceptance criteria are unclear or results appear inconsistent.
• Direct the collection and analysis of test data, evaluate results against acceptance criteria, review detailed test reports for technical adequacy, and maintain configuration control of test records.
• Lead troubleshooting of complex system issues identified during testing in coordination with Responsible Engineers and equipment vendors, diagnosing problems and directing implementation of corrective actions.
• Turnover and Coordination
• Lead system turnover activities from construction to commissioning by verifying that systems meet mechanical completion criteria, documentation is complete and accurate, and prerequisites for testing are satisfied.
• Represent the commissioning organization in the Joint Test Group, presenting test results, resolving technical concerns through proper channels, and coordinating complex multi-discipline testing with engineering, construction, operations, and QA organizations.
• Lead progressive system turnover to operations by ensuring test completion, punch list resolution, and documentation readiness for operational acceptance.
• Work closely with Responsible Engineers to clarify design intent, validate test approaches, and resolve complex design-related questions through disciplined technical inquiry.
• Collaboration, Quality, and Compliance
• Collaborate with Operations personnel during testing to validate operating procedures and lead transition to operational responsibility.
• Direct coordination with Maintenance craft during equipment installation checks, functional testing, and troubleshooting activities in accordance with disciplined work control processes.
• Coordinate with QA inspectors to ensure testing complies with quality requirements, hold points are observed, documentation meets quality standards, and configuration control is maintained throughout commissioning.
• Review and approve documentation for accuracy, completeness, and traceability to support regulatory inspections and operational readiness assessments.
• Ensure all testing activities comply with safety requirements, work authorization processes, and environmental controls, and foster a culture where questioning attitude is expected and consistently applied.
• Lead pre-job briefings, hazard identification, and work control processes, and monitor test conditions for off-normal situations requiring protective action or stop-work authority.

Job Profile Minimum Qualifications

• Bachelor's degree in engineering, including mechanical, electrical, chemical, nuclear, or related discipline, from an ABET-accredited institution.
• Level IV:
• Typically, 10 years of relevant experience in commissioning, startup, operational testing, or maintenance in nuclear, chemical process, pharmaceutical, or other highly regulated industries.
• Experience developing or executing test procedures, collecting and analyzing test data, and documenting results with disciplined attention to accuracy and completeness.
• Exposure to integrated systems operation, testing, and troubleshooting in procedurally controlled environments.
• Ability to read and interpret P&IDs, electrical schematics, control logic diagrams, and technical specifications.
• Strong problem-solving capability and a systematic approach to troubleshooting.
