Full Job Description

Process Design Engineer (Water & Wastewater)

Innova Water Pty Ltd – Ascot, Brisbane QLD
$115,000 – $140,000 + Super

About the Role

Innova Water is seeking a mid-level Process Design Engineer to join our Brisbane team.

This role is ideal for an engineer with 4–6 years' experience who can take ownership of design packages, work directly with clients, and contribute across design, construction and commissioning.

You will:

Work independently on smaller projects
Support a Senior Engineer on larger, complex designs
Take ownership of technical design, coordination and client interaction

This role is suited to a practical engineer who enjoys seeing designs built and commissioned — not just developed on paper.

This is not a purely desktop design role — you will be involved in site work, commissioning and real-world project delivery.

Key ResponsibilitiesProcess Design

Develop and review:
Process Flow Diagrams (PFDs)
Piping & Instrumentation Diagrams (P&IDs)
Mass balances
Complete process design calculations across water and wastewater treatment units
Perform:
Equipment sizing and selection (pumps, blowers, valves and process equipment)
Hydraulic assessments and system design
Prepare and review:
Basis of Design reports
Detailed design reports
Develop:
Functional descriptions
Process control philosophies

Design Coordination & Project Delivery

Coordinate with civil, structural, mechanical, electrical and controls disciplines
Review drawings, specifications and design deliverables
Manage RFIs, technical queries and design actions
Prepare:
Technical specifications
Scopes of work
Review:
Vendor submissions and equipment selections
Participate in client meetings and design reviews
Provide guidance to junior engineers/designers

Risk & Technical Reviews

Participate in structured risk processes including:
HAZOP
CHAIR workshops (1/2/3)
CHAZOP

Construction, Commissioning & Handover

Prepare:
Commissioning Plans
Proof of Performance (PoP) plans
Provide on-site commissioning support, testing and fault finding
Conduct site inspections and support construction activities
Prepare:
O&M manuals
SOPs
Operator training materials
Support contractors and clients through construction and startup

About You

Australian Permanent Residency or Citizenship is required for this position.

Essential

Degree in Chemical Engineering

(Civil or Environmental considered with strong process focus)

4–6 years' experience in water, wastewater or a closely related process industry

(minimum 3 years required)

Demonstrated ability to:
Develop PFDs, P&IDs and process calculations independently
Contribute to and review technical design documentation
Experience writing:
Functional descriptions and/or control philosophies
Strong communication skills and ability to be client-facing
Willingness to be involved in site work, commissioning and construction support
Demonstrated interest in building a career in water and wastewater infrastructure

Highly Regarded

Experience with:
Treatment plants, pump stations, pipelines or recycled water systems
Exposure to:
Design coordination across disciplines
Managing junior engineers/designers
Experience from:
Engineering consultancies or construction/project delivery roles
Experience with:
AutoCAD (essential)
Basic AutoCAD drafting proficiency is required for this role.
Other process modelling or design software

Not a Perfect Fit? Still Apply

We recognise strong engineers don't always come from identical backgrounds.

We will consider:

Engineers from construction or contractor environments with strong delivery and client-facing experience
Candidates with minor gaps in specific design areas who demonstrate high capability, ownership and practical project experience

About Innova Water

Innova Water is a specialist process and hydraulic design consultancy focused exclusively on water and wastewater infrastructure.

Based in Brisbane (Ascot), delivering projects across Australia's east coast
Working on treatment plants, pump stations, pipelines and recycled water infrastructure
A young, high-performance consultancy (small team, high accountability)
Focused on delivering practical, construction-ready designs and supporting projects through commissioning and handover

Why Join Innova Water?

Accelerated technical development compared with large consultancies
Early exposure to:
Client interaction
Real design decisions
Site and commissioning work
Small, high-trust team where your contribution matters
Opportunity to grow with the business

You will see your designs through to construction, commissioning and operation — and be directly involved when things don't work as expected.

Working arrangements:

Based in Ascot (Brisbane inner north)
Predominantly office-based
Up to 1 day per week work-from-home
Short periods of site work throughout the year

Salary & Incentives

$115,000 – $140,000 + super (depending on experience and capability)

Pay: $115,000.00 – $140,000.00 per year
