• Drive QA/QC programs and resolve technical issues that arise during field execution.

Codes, Standards & Regulatory Compliance

• Ensure full compliance with PHMSA, DOT, WVPSC, and applicable state and federal pipeline regulations.
• Partner with Permit Manager and Energy Attorney on regulatory filings, FERC matters, and compliance obligations.
• Establish and maintain pipeline integrity management and operator qualification programs.

Operations Interface & Commissioning

• Lead pipeline commissioning, purging, and start-up in coordination with the O&M team.

About You

• 10+ years of experience in natural gas pipeline engineering, construction, or operations.
• PE license (Mechanical or Chemical) strongly preferred.
• Deep working knowledge of 49 CFR 192, ASME B31.8, API standards, and PHMSA enforcement practice.
• Background in gathering, transmission, or large industrial fuel gas systems.
• Demonstrated ability to manage EPC contractors and outside engineering on aggressive schedules.
• Houston-based with willingness to travel to Mason County, WV as required.
