About Us
HBK Engineering, LLC is a fully licensed, professional engineering design firm headquartered in Chicago, IL with a staff approaching 700 individuals. HBK provides civil, environmental, structural, electrical, subsurface utility, construction support services and permitting facilitation. Since our founding in 1998, we have earned a reputation for delivering outstanding, accurate services in extremely time-sensitive, multilayered environments. That "industry-recognized" performance has propelled our expansion and the ability to provide engineering services in all 50 states. With 25 offices nationwide, including concentrations in the Midwest and on the Coasts, HBK brings together a dedicated team whose main focus is the design and protection of utilities and utility networks. We have successfully performed engineering work for a complete spectrum of utility infrastructure projects providing solutions and construction support from Coast to Coast in areas ranging from complex urban city centers, to rural greenfields, to limited access rights-of-way. In July 2020, HBK Engineering was acquired by Quanta Services. Quanta Services provides infrastructure services for electric power, pipeline, and communications industries and employees over 50,000 people. Quanta’s focus on the utility industry and HBK’s focus on constructability in our designs has made our integration into the Quanta family of companies seamless.
About this Role
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.
What You'll Do
- 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.
- Travel and extended hours may be required, up to 50% travel
- For candidates outside the Butte area, a minimum of two days per week onsite in Butte is required during the initial training period. Once training is complete, management will evaluate and determine ongoing onsite expectations
Regulatory Compliance & Permitting
- 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.
What You'll Bring
- 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.
- Familiarity with gas design standards, specifications, and regional operating considerations is a major plus.
- Proficiency with design and mapping platforms such as AutoCAD, Civil 3D, MicroStation, or ArcGIS.
- Exposure to gas hydraulic modeling software (e.g., Synergi Gas, NextGen, WinFlow) and pipe stress analysis tools.
- Proven problem-solving capabilities and attention to detail.
- Flexibility to travel periodically across Montana for site visits, field walkdowns, and client alignment meetings.
What You'll Get
- Opportunity to work independently on complex engineering challenges
- Collaborative work environment with interdisciplinary teams
- Travel opportunities for field work and client engagement
- Comprehensive benefits package
- Career advancement opportunities with increased responsibilities.
