Lead Process Engineer reports to theHead of Discipline – Process

The Lead Process Engineer shall be responsible for leading and delivering basic engineering (Pre-FEED/FEL-2 and FEED/FEL-3) for refinery core processing units. The role ensures high-quality process design, technical integrity, and alignment with project requirements, safety standards, licensor guidelines, and client expectations. Lead basic engineering of refinery core process units (e.g., CDU/VDU, FCCU, Hydrocrackers, Hydrotreaters, Reformer, Coker/Crackers) in greenfield and brownfield set‑up.

In your role you are expected to demonstrate your proven track record in maintaining proper resourcing in terms of capacity and competence as well as in well organizing projects with proper work sharing, tracking of progress & coordination with Inter disciplines and counter parts/client.

You should have a desire to work on multi-disciplinary local as well overseas projects and be able to drive discipline goals by leading assigned discipline designers and engineers.

Hunger for learning and sharing new ideas will be the cornerstone of your success. We also value people for whom safety are part of their professional skills.

• Lead development of Process Design Basis, Heat and Material Balance (H&MB), PFDs, P&IDs, utility summaries, and process descriptions for core refinery/petrochemical units.

• Define design and operating conditions, equipment duty specifications, and preliminary sizing and validation of distillation columns, reactors, exchangers, compressors, furnaces.

• Prepare and review key engineering documents:

  • Process datasheets

  • Cause & Effect diagrams

  • Control philosophies

  • Process safeguarding narratives

  • Equipment lists and process interfaces

• Ensure design consistency with licensor packages, site constraints, and refinery-wide integration (LP model, utilities, offsites).

  • Lead technical discussions with process licensors (e.g., for FCC, Hydrocracker, Coker, Reformer units).

  • Review and validate licensor design packages (PFDs, catalyst requirements, reaction systems, heat integration).

  • Serve as the primary technical interface for client queries, approvals, and design reviews.

    Coordinate with multi-disciplinary teams (mechanical, piping, control, HSE, civil, electrical, project controls).

  • Develop, validate, and maintain rigorous process simulation models using HYSYS, PRO/II, or equivalent.

  • Perform scenario analysis, sensitivity studies, debottlenecking evaluations, and design optimization.

  • Ensure accuracy of utility consumption, energy integration opportunities, and emission estimates.

  • Provide process engineering deliverables for capital projects: feasibility studies, FEL stages, PFDs, P&IDs, heat and material balances, equipment sizing, and process control strategies.

  • Support the development of the cost estimates and economic analysis.

  • Review and approve design packages from EPC contractors and vendors.

  • Lead commissioning and performance testing of new or revamped units.

  • Evaluate and implement new technologies to improve energy efficiency, decarbonization, and product…
