About The Position

HBK Engineering, LLC is seeking an experienced Gas Transmission Engineer to support our natural gas utility infrastructure practice in Montana, with a primary focus on engineering design and delivery. In this role, you will perform and lead engineering design, technical evaluations, permitting support, and regulatory compliance for high-pressure natural gas transmission pipelines, regulator stations, valve assemblies, and interconnect facilities. You will collaborate closely with multi-disciplinary project teams, utility client representatives, and local/state agencies to deliver safe, reliable, and cost-effective gas engineering solutions from initial planning through construction support.

Requirements

Bachelor of Science degree in Mechanical Engineering, Civil Engineering, Petroleum Engineering, or an accredited engineering discipline.
4+ years of relevant engineering experience in natural gas transmission, high-pressure gas distribution, or pipeline utility design.
Proficiency with design and mapping platforms such as AutoCAD, Civil 3D, MicroStation, or ArcGIS.
Proven problem-solving capabilities and attention to detail.
Flexibility to travel periodically across Montana for site visits, field walkdowns, and client alignment meetings.

Nice To Haves

Familiarity with gas design standards, specifications, and regional operating considerations is a major plus.
Exposure to gas hydraulic modeling software (e.g., Synergi Gas, NextGen, WinFlow) and pipe stress analysis tools.

Responsibilities

Lead and perform engineering design for natural gas transmission pipelines, gate stations, town border stations, regulator/metering facilities, and main line valve settings.
Prepare detailed engineering calculations including pipe wall thickness, hoop stress/MAOP determinations (ASME B31.8), cathodic protection evaluations, pressure relief sizing, and hydraulic flow modeling.
Function as project engineer for natural gas facilities such as pipelines, measurement & regulation stations, compressor stations or gas treatment equipment
Direct and review the preparation of alignment sheets, P&IDs, facility piping layouts, detail drawings, and Bills of Materials (BOMs).
Perform Quality Assurance / Quality Control (QA/QC) technical reviews on design packages to ensure compliance with client standards, safety codes, and industry best practices.
Act as a primary day-to-day engineering point of contact for gas design and operations teams.
Ensure all design packages, material specifications, and standard operating procedures (SOPs) align with utility standards.
Respond to field Requests for Information (RFIs) and engineering change orders during construction to ensure design intent is maintained.
Ensure all project deliverables comply strictly with DOT 49 CFR Part 192, ASME B31.8, PHMSA mandates, and state regulations (Montana PSC).
Support environmental, land, and agency permitting processes through coordination with the Montana Department of Transportation (MDT), Bureau of Land Management (BLM), US Forest Service (USFS), railroads, and local municipalities.
Assist with Integrity Management Program (IMP) evaluations, maximum allowable operating pressure (MAOP) re-confirmation programs, and pipeline risk mitigation projects.
Support Project Managers with scope development, engineering fee estimations, schedule tracking, and technical risk identification.
Participate in client progress meetings, site walkdowns, and field investigations across Montana as required.
