Job Description

Be at the center of SEMCO's natural gas operations. As a Gas Controller, you'll monitor and manage the flow of natural gas across our pipeline system, helping ensure safe, reliable service for the communities we serve. From balancing gas supply and storage to coordinating field response activities and managing system conditions in real time, you'll play a critical role in keeping the gas system operating safely and efficiently.

We're looking for someone who thrives in a dynamic environment, pays close attention to detail, communicates effectively, and can adapt quickly as operating conditions change. If you enjoy solving problems, making decisions, and taking ownership of critical operations, this role offers the opportunity to make a direct impact every shift.

Key Responsibilities:

  • Respond to alarms, alerts, and abnormal operating conditions in a timely manner following established procedures.
  • Communicate system issues to appropriate personnel and coordinate field response activities when necessary.
  • Balance daily gas supply contracts and on-system storage by adjusting gate station and storage facility flow rates.
  • Support SEMCO's 24/7 operations by working a rotating 12-hour swing-shift schedule and adhering to Fatigue Mitigation requirements. This includes day and night shifts, required overtime, coverage for team members as needed, and approximately 50% of company-observed holidays.
  • Document system changes and operating activities in accordance with Change Management, Shift Turnover, Daily Log, and other CRM requirements.
  • Complete required control room documentation, including False Alarm Reports, Ambiguous Description Reports, Deviation Logs, and other documentation mandated by the O&M Manual.
  • Prepare and distribute routine and special reports as required.
  • Primarily work a rotating swing-shift schedule.

Minimum Qualifications

  • Associate degree, vocational training, or equivalent coursework in a technical field preferred.
  • Two to four years of experience in the natural gas industry preferred.

Knowledge, Skills, and Abilities

  • Strong analytical, problem-solving, and organizational skills.
  • Effective verbal and written communication abilities.
  • Proficiency with Microsoft Office and other business software applications, with the ability to learn new systems and technologies.
  • Basic understanding of mechanical systems, pipeline operations, and natural gas infrastructure.
  • Ability to work independently and make sound operational decisions.
  • Ability to obtain and maintain Operator Qualifications (OQ) in Gas Control, Control Room Management, and Fatigue Mitigation.

Additional Requirements

  • Maintain positive and professional working relationships with coworkers, customers, and management.
  • Reside within 45 minutes of the Company's Control Room.
  • Promote and maintain a safe work environment by following established safety procedures and promptly reporting hazards.
  • Comply with all Company policies, including business ethics, regulatory compliance, responsible use of company assets, and all applicable federal and state regulations.

We offer a competitive hourly rate ranging from $26.83 to $38.91 per hour, with opportunities for overtime based on operational needs. Employees are also eligible for a comprehensive benefits package that includes medical coverage, retirement savings programs, and paid time off.
