Maintenance Planner – Mobile & Fixed Plant

About Helix

Helix Asset Management is a Perth-based maintenance and asset management consultancy firm working with mining and civil operations across WA. Planning is at the core of what we deliver - it's the difference between a maintenance team that's always catching up and one that's consistently ahead of the curve. We embed planners directly into client operations, either on-site or through our centralised Perth-based planning model, and we hold our work to a standard that actually moves the needle on availability and cost.

The Role

We're looking for experienced Maintenance Planners to join the Helix team, supporting mining clients across WA on mobile and fixed plant assets. This is a core delivery role - you'll be responsible for producing high-quality, executable work plans that give trades the right information, the right parts, and the right time allocation to get the job done properly the first time.

Good planning isn't about processing work orders. It's about understanding the equipment, anticipating what the job actually involves, coordinating the resources and parts before the spanner hits the bolt, and making sure the scheduler and supervisor have everything they need to run a clean week. If that's how you think about the role, we want to hear from you.

We have opportunities for both site-based FIFO planners embedded directly within client maintenance teams, and Perth-based planners operating within Helix's centralised planning model - delivering remote planning services across multiple client sites simultaneously.

What You'll Be Doing

Developing detailed, executable work plans for corrective and preventive maintenance work orders - including scope of work, labour hours, trade disciplines, parts, tools, permits, and access requirements

Managing and maintaining the planning backlog - prioritising work in line with equipment criticality, operational requirements, and available maintenance windows

Coordinating parts and materials requirements ahead of scheduled work - raising purchase requisitions, confirming stock availability, and liaising with stores and procurement to ensure parts are on hand before work commences

Working closely with schedulers and maintenance supervisors to produce realistic, achievable weekly maintenance schedules - and supporting the scheduling meeting process

Reviewing and closing out completed work orders - capturing actual vs planned hours, identifying scope variances, and feeding findings back into future planning

Maintaining and improving PM task lists and job plans within the CMMS to ensure planned work reflects current maintenance strategies and equipment requirements

Tracking and reporting on key planning metrics - plan compliance, backlog age, parts availability, schedule adherence - and identifying trends that need attention

Supporting shutdown and campaign maintenance planning - scope development, resource planning, materials coordination, and pre-shutdown readiness checks

Liaising with reliability and engineering teams to ensure corrective actions and improvement recommendations are captured and planned into the work queue

Identifying opportunities to improve planning processes, job plan quality, and CMMS data accuracy

What We're Looking For

Non-negotiables:

Trade qualification in a relevant discipline - Heavy Diesel, Fitting, Boilermaking, Electrical, or equivalent - you need to understand the work you're planning

Minimum 3 years in a dedicated maintenance planning role within the mining or heavy industry sector

Solid experience with at least one CMMS platform - SAP PM, Pronto, Maximo, Ellipse, or similar - used for work order management, PM scheduling, and parts coordination

Strong understanding of the full planning cycle - from work identification through to work order close-out and feedback loop

Demonstrated ability to produce detailed, high-quality job plans that trades can actually execute without constant clarification

Good working knowledge of parts and materials management as it relates to maintenance planning

Organised, methodical, and consistent - planning quality can't vary week to week depending on workload

Highly regarded:

Experience in either mobile plant orfixed plant planning environments

Shutdown or campaign planning experience - scope development, resource coordination, materials management

Experience operating within a centralised or remote planning model

Exposure to reliability improvement activities - defect elimination, RCFA support, PM optimisation

Familiarity with planning KPIs and reporting - you understand what the numbers mean, not just how to produce them

Experience across multiple sites, commodities, or operation sizes

Background with Tier 1 or Tier 2 operators (BHP, Rio Tinto, Mineral Resources, Newmont, or similar)

What Makes This Different

Planning at Helix isn't a siloed, heads-down role. You'll be working alongside consultants and engineers who understand what good maintenance looks like end to end, which means you'll have the support and context to do your best work - not just push work orders through a queue.

For planners interested in the centralised model, this is a genuinely different way of working - supporting multiple client sites from Perth, building broad exposure across different operations and asset types, without the roster grind of permanent FIFO. It suits people who are sharp, self-directed, and want to build depth quickly across a variety of environments.

For site-based roles, you'll be embedded directly within a client maintenance team with Helix backing - clear standards, peer support, and a consultancy that actually knows what good planning looks like.

The Practical Stuff

FIFO or Perth-based (centralised model) depending on role type and candidate preference

Contract day rate or ongoing engagement - negotiated based on experience

Exposure to a variety of clients, asset types, and operation sizes

Perth support hub for centralised planning, reporting, and team collaboration
