Full Job Description

The Opportunity

Mineral Technologies, a wholly owned Downer company and global leader in mineral processing solutions, is seeking an experienced Senior Designer Mechanical P&ID to join our Engineering & Projects team.

This is a unique hybrid role that combines P&ID ownership with advanced piping design and 3D modelling capability. You will be responsible for developing and maintaining P&IDs from process intent through to Issue for Construction documentation, while carrying that intent through the 3D piping model, isometrics and fabrication packages.

Working alongside Process Engineers, Mechanical Engineers and multidisciplinary project teams, you will play a critical role in delivering high quality designs for mineral processing projects across Australia and internationally.

This position is ideally suited to a designer who can work independently, apply sound engineering judgement and confidently develop solutions from first principles rather than relying on detailed mark ups.

Key responsibilities include:

Develop P&IDs from process flow diagrams, mass balances and equipment lists
Own P&ID development throughout the project lifecycle from concept to as built documentation
Establish and maintain line numbering, equipment tagging and instrument conventions
Identify and apply specification breaks, isolation philosophy, drains, vents, sample points and service connections
Develop 3D piping models in AutoCAD Plant 3D
Produce general arrangements, isometrics, support drawings and material take offs
Coordinate clash detection and multidisciplinary design reviews
Lead P&ID squad checks and technical quality reviews
Support capability development across the drafting and design team

What We're Looking For

To be successful in this role, you will bring extensive experience in process plant design drafting with a strong focus on P&ID development and piping design.

You will be able to demonstrate the ability to:

Take a flowsheet and mass balance and develop a first pass P&ID that requires review rather than complete redevelopment
Define and justify specification breaks and understand the impact of incorrect placement
Build and manage line numbering systems across large and complex projects
Interpret instrument tags and understand complete control loop requirements
Route slurry pipelines with consideration for velocity, wear, maintenance, drainage and flushing requirements
Configure and manage AutoCAD Plant 3D projects including specifications, catalogues, class definitions and validation rules
Deliver piping designs from P&ID through to fabrication ready drawing packages

You will also possess:

Trade qualification, Advanced Diploma or associate degree in drafting, design or a related engineering discipline
10+ years' experience in process plant design drafting
Minimum 5 years' experience producing P&IDs as a primary deliverable
Demonstrated ownership of P&ID development on major projects
Advanced AutoCAD Plant 3D capabilities across both P&ID and piping disciplines
Experience within mining, mineral processing or heavy industrial environments
Strong understanding of ISA 5.1 tagging standards and recognised P&ID conventions
Experience using smart P&ID systems and associated databases

What We Offer

At Mineral Technologies and Downer, we are committed to supporting our people and providing opportunities to grow and succeed.

You will have access to:

Flexible working arrangements
Opportunity to work on complex mineral processing projects across global operations
A collaborative and highly experienced engineering team
Career development and professional growth opportunities
Employee benefits and wellbeing programs
A strong safety and inclusion focused culture
