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.
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 mining sustaining capital and brownfield projects.
Develop and review pipeline design documentation, including mass and energy balances, PFDs, P&IDs, process descriptions, and design reports.
Support concept studies, feasibility assessments, and detailed design phases with Pipeline modelling and optimisation input.
Liaise with operations teams to understand plant performance issues and develop improvement strategies.
Provide technical mentorship and guidance to junior Pipeline engineers and designers.
Ensure all designs comply with WSP’s quality standards, client requirements, and relevant Australian and international codes and standards.
Contribute to project planning, cost estimation, and risk assessments for process-related scopes.
Make technical presentations internally, to clients and to outside organisations.
To ensure that process safety issues are fully considered within projects eg. HAZOP, LOPA, hazardous area classification, SIL reviews.
Contribute to:
Maintenance strategies
System operability and reliability improvements
Provide practical, field-aligned engineering solutions
