Key Responsibilities

Position Overview


The Lead Pipeline Engineer is responsible for leading pipeline engineering activities during pre-bid, proposal, and detail engineering stages for EPC projects involving cross-country pipelines, gas transmission, water transmission, and and associated facilities. The role ensures high-quality engineering deliverables, optimized design solutions, compliance with standards, and technical coordination across disciplines.

Key Responsibilities

------------------------

1. Pre-Bid Engineering & Proposal Support

------------------------------------------------

Review tender documents, project specifications, route maps, alignment sheets, and client requirements. Prepare preliminary pipeline designs, route selection analysis, hydraulic calculations, and material take-offs (MTOs). Support preparation of technical proposals, value-engineering options, and deviations/clarifications. Provide pipeline-related assumptions, design basis, and technical inputs for cost estimation teams. Review vendor information for line pipe, valves, fittings, corrosion protection systems, and other pipeline components during proposal stage.

2. Detail Engineering Responsibilities

-------------------------------------------

Lead the development of engineering deliverables including: Pipeline design basis Route selection reports Alignment sheets Pipeline wall thickness calculations Stress analysis (buried, above-ground, crossings) Surge analysis (for water pipelines) Cathodic protection design Station piping layouts and isometrics Review and validate P&IDs, GA drawings, pipeline material specifications, and construction drawings. Ensure alignment with relevant codes/standards (ASME B31.4/B31.8, API 5L, DNV, AWWA, ISO, NACE). Coordinate with GIS, civil, process, mechanical, and instrumentation teams for integrated design.

3. Crossings, Route Engineering & Special Studies

-------------------------------------------------------

Evaluate and design road crossings, railway crossings, river crossings (HDD, micro-tunneling), canal crossings, and other critical sections. Support geotechnical investigations, soil reports, and topographical surveys. Perform risk assessments, pipeline integrity studies, and constructability reviews.

4. Interface Management

----------------------------

Coordinate with: Process & hydraulic teams Civil & structural teams Electrical & CP teams Vendor engineering (valves, fittings, CP, coatings) Procurement and construction teams Resolve multidisciplinary technical issues and ensure complete engineering integration.

5. Construction & EPC Support

-----------------------------------

Provide technical support to procurement teams during TBE (Technical Bid Evaluations). Review vendor drawings, data sheets, pipe mill documents, and FAT/SAT reports. Support site teams with engineering clarifications, as-built reviews, and troubleshooting. Ensure seamless transition of engineering packages to construction and commissioning teams.


We are known for our extraordinary people who make the impossible possible every day. Questians are driven by hunger, humility, and aspiration. We believe that our company culture is the key to our ability to make a true difference in every industry we reach. Our teams regularly invest time and dedicated effort into internal culture work, ensuring that all voices are heard.



We wholeheartedly believe in the diversity of thought that comes with fostering a culture rooted in respect, where everyone belongs, is valued, and feels inspired to share their ideas. We know embracing our unique differences makes us better, and that solving the worlds hardest engineering problems requires diverse ideas, perspectives, and backgrounds. We shine the brightest when we tap into the many dimensions that thrive across over 21,000 difference-makers in our workplace.
