WSP India is currently seeking a Principal Engineer Mechanical (Pump & Pipeline) for Australia Mining Infrastructure Projects (Materials Handling Infrastructure). They shall be responsible for engineering design of Process with WSP Engineering and Client Standards. Previous experience in an EPCM environment in the O & G, Power plant, Chemical process plant, Mining processing industry is an asset. A Team player and willing to work collaboratively with a motivated and highly successful team in Australia. The position will be for Mumbai location. About the role: We are seeking a Principal Engineer to support mining infrastructure projects across Australia, with a strong focus on pumping systems, pipeline networks, and water management systems. This is a hybrid role combining process engineering, hydraulic analysis, and pipeline/pumping system design, rather than a conventional EPC-style discipline role. The position will lead technical delivery, mentor engineers, and interface with multidisciplinary teams across Australia and India. The role requires close collaboration and effective coordination with clients, multidisciplinary engineering teams, vendors, suppliers, pipeline route survey consultants, geotechnical investigation teams, construction contractors, and other key stakeholders to ensure engineering excellence, compliance with project requirements, timely delivery of deliverables, and successful project execution. Technical Leadership Lead design and analysis of: Pumping systems (HP pumps, transfer systems) Pipeline and network systems (water, slurry, dewatering) Define system philosophy: Pumping strategy and operating scenarios Overpressure and surge protection philosophy Brownfield integration and tie-ins Provide technical assurance and review of key deliverables like Pipeline route selection and feasibility studies, material selection, wall thickness design, pipeline stress analysis in accordance with applicable international codes and standards, design of crossings for highways, roads, railways, rivers, and other utilities, pipeline integrity management, identification and mitigation of geohazards, and preparation of material specifications and other engineering deliverables. Undertake and lead pipeline design work for projects and studies including typical activities and deliverables: - Concept design and layout development Process descriptions and design basis Material balances Preparation of process flow diagrams & piping and instrumentation diagrams Hazardous area classification/assessment Preparation of equipment lists, equipment datasheets, specifications Fluids lists and materials selection Process hazard studies (including HAZOP) and design safety reviews SIL assessment Process basis of safety Detailed process design calculations Pressure relief design Utilities schedules, utilities flow diagrams and line sizing Preparation of validation documentation Commissioning plans and support Prepare the following for pipelines and their components: Material specifications and datasheets Fabrication specifications Installation specifications Pipeline design and installation, stress analyses Material takeoffs Bids & Proposal support Pipeline reports and installation manual To ensure technical excellence in Pipeline engineering and design. Develop and review: Basis of Design (BoD) Design criteria and technical specifications P&IDs and process schematics Hydraulic calculations and reports Perform and validate: Hydraulic modelling (PumpSim, or equivalent) Flow scenarios and system behaviour Pipe sizing and pressure rating Review and guide: Pipe class and valve class selection Pump selection and system curves Co-ordination of a design to ensure good interface with all other disciplines. Participation in design reviews and technical audits. Input into multi-discipline design programmes. Contributing to processes to maintain change & cost control. Develop the strength of the expertise within the Pipeline engineering department. Support/generate cost and manhours estimate for proposals, studies and projects. Act as Lead Pipeline Engineer on selected projects controlling design, specifications, costs, hours, quality and programme. Lead and deliver Pipeline engineering scopes for
