Senior Engineer - Process

We are seeking a Principal Process 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. 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

Undertake and lead process 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

To ensure technical excellence in process 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 process engineering department.

Support/generate cost and manhours estimate for proposals, studies and projects.

Act as Lead Process Engineer on selected projects controlling design, specifications, costs, hours, quality and programme.

Lead and deliver process engineering scopes for mining sustaining capital and brownfield projects.

Develop and review process 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 process modelling and optimisation input.

Liaise with operations teams to understand plant performance issues and develop improvement strategies.

Provide technical mentorship and guidance to junior process 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

Client / External focus Maintain strong colleague relationships and contribute to the teams’ performance of client satisfaction.

Contribute to knowledge sharing in internal and external forums.

Remain up to date with market and competitor knowledge.
