Mechanical Engineer IV - Job ID: 3957

RISINGSUN TECHNOLOGIES is seeking a Senior QME-1 Valve Qualification Engineer to support the qualification of nuclear safety-related active mechanical equipment, especially hydraulic control unit scram valves. The role evaluates qualification methods, testing, documentation, evidence, and technical risks while coordinating with engineering teams, suppliers, and external laboratories.

Responsibilities:

• Support qualification of valve assemblies, actuators, pilot valves, hydraulic/pneumatic interfaces, accumulators, and stored-energy actuation systems
• Review qualification specifications, plans, test procedures, procurement inputs, test reports, and objective evidence packages
• Evaluate test article configuration, qualification boundaries, credited functions, acceptance criteria, production representativeness, and differences between tested and production configurations
• Assess actuator and pilot valve interfaces, hydraulic/pneumatic connections, mounting, tubing, test fixtures, instrumentation, and data acquisition setups
• Review procedures for functional, leakage, response-time, endurance, seismic, environmental/DBA, thermal-aging, and radiation-aging testing
• Support test readiness reviews, including calibration status, measuring and test equipment (M&TE), witness/hold points, safety considerations, and unresolved readiness items
• Provide technical oversight during qualification testing, including witness support, interim data review, anomaly identification, retest planning, and issue escalation
• Review raw and reduced data, calibration records, as-tested configurations, test logs, photographs/videos, and supporting qualification evidence
• Support disposition of anomalies, nonconformances, deviations, configuration differences, and incomplete or inconsistent evidence
• Contribute to Qualification Reports, Application Reports, qualification summaries, and certification documentation
• Communicate qualification risks, assumptions, open actions, constraints, and schedule impacts
• Coordinate with Design Engineering, Test Engineering, Quality Assurance, Materials, Procurement, Project teams, suppliers, and test laboratories
• Maintain compliance with applicable engineering processes, nuclear quality requirements, configuration controls, and industry codes and standards

Requirements:

• ASME QME-1
• Valve qualification
• Vendor test oversight
• ASME code documentation
• Qualification Report preparation and review
• Application Report preparation and review
• Professional Engineer (PE) license
• Bachelor's degree in Mechanical Engineering, Nuclear Engineering, or a related engineering discipline
• Minimum 10 years of relevant experience in nuclear engineering, power generation, mechanical equipment qualification, valve engineering, or safety-related equipment testing
• Experience with ASME QME-1 or closely related nuclear mechanical equipment qualification standards
• Experience with valves, actuators, pilot-operated/solenoid pilot valves, hydraulic/pneumatic systems, accumulators, or pressure-boundary components
• Experience developing or reviewing qualification plans, specifications, procedures, acceptance criteria, test reports, and evidence packages
• Experience supporting supplier, fabricator, or external laboratory qualification activities
• Familiarity with nuclear quality assurance, controlled documentation, configuration management, traceability, and objective evidence requirements
• Strong technical judgment, written and verbal communication, and cross-functional collaboration skills
• Direct ASME QME-1 valve qualification through testing, analysis, and similarity/equivalence evaluations
• ASME Section III/NCA, N-Certificate Holder responsibilities, and nuclear component certification interfaces
• IEEE 382, seismic/environmental qualification, thermal/radiation aging, and DBA/LOCA testing
• Fail-safe valve actuation and hydraulic/pneumatic stored-energy systems
• International suppliers, translated technical documentation, and cross-company responsibility allocation
• Technical leadership, mentoring, and clear judgment regarding engineering, quality, supplier, and code responsibility ownership
