• Maintains and configures the leak detection software models for pipeline leak detection
• Troubleshoots and supports pipeline hydraulic operations
• Performs surge analysis and transient hydraulic modeling to evaluate pressure wave propagation, waterhammer effects, and pump start/stop scenarios; develops mitigation strategies including surge relief valve sizing and pipeline pressure rating assessments
• Develops and maintains steady-state and dynamic hydraulic models to support pipeline capacity studies, drag-reducing agent (DRA) optimization, and operational feasibility assessments for contingency scenarios
• Participates in the development of specifications and recommendations for process control applications
• Configures software to support new functionality as well as participating installation and operation activities
• Provides support on matters requiring immediate diagnostic response on critical system outages
• Partners with Operations Control and Pipeline Integrity to determine assets and prioritization
• Monitors and tunes the software leak detection models
• Assists in ensuring the leak detection and rupture detection systems meet all applicable regulations
• Maintains a dashboard with KPIs on the leak detection system performance
• Partners with engineers and management to implement API 1175
• Administers and leverages data historian platforms (e.g., OSIsoft PI, Seeq) to retrieve, trend, and analyze pipeline operational data in support of leak detection and hydraulic performance evaluations
• Trains Control Room personnel on the leak detection system and pipeline hydraulics
• Gathers, analyzes, interprets, acts upon, and disseminates pertinent data from the SCADA system, pipeline leak detection system and data historians
• Maintains other SCADA-related layered apps as needed
• Accepts after hour calls
• Interfaces with operation departments to communicate and define their role in compliance efforts

Special assignments or tasks assigned to the employee by their manager, as determined from time to time in their sole and complete discretion

A minimum of seven years of job-related experience is required.

PREFERRED EXPERIENCE:

Experience in pipeline modeling, SCADA, or leak detection processes.

Familiarity with waterhammer mitigation design, pump station hydraulics, and pipeline pressure rating evaluations is a plus. 

A minimum of a Bachelor's Degree in Mechanical, Chemical, Petroleum, Civil Engineering, or a closely related technical field is required.

Strong understanding of pipeline instrumentation and fluid dynamics, including steady-state and transient hydraulic principles, surge pressure analysis, and waterhammer phenomena. Advanced knowledge of engineering concepts with demonstrated ability to apply analytical and problem-solving skills to complex pipeline systems. Knowledge of Microsoft products such as Outlook, Word, and Excel is required. Understanding of pipeline processes, SCADA systems, and leak detection fundamentals is required. Good reading, presentation; ability to effectively communicate with others, both written and verbal communication, and lead training classes.  Ability to perform basic mathematical calculations, advanced level reading and writing skills.

PREFERRED SKILLS:

Proficiency with hydraulic modeling and transient simulation software such as AFT Impulse, AFT Fathom, PIPESIM, SPS, or equivalent tools is strongly preferred. Experience with pipeline leak detection platforms (e.g., AVEVA PIM, OASys CVB, Atmos) and data historian systems (e.g., OSIsoft PI, Seeq) is preferred. Familiarity with API RP 1130, API RP 1175, and applicable PHMSA pipeline safety regulations is highly desirable. Experience with SCADA systems, control room management, and real-time transient modeling (RTTM) is a plus. Knowledge of DRA injection systems, pump station hydraulics, and pipeline capacity optimization is preferred.

Provides technical leadership and mentorship to junior engineers and technicians. May lead the work of others, coordinate cross-functional project teams, and serve as the primary technical authority on leak detection and hydraulic engineering matters within the department.

Office and Pipeline Control Room environment based with up to 20% travel required.  Subject to varying weather conditions and required to work in all temperatures, including outdoors.
