Harnest is the social and affordable housing arm of Mazzei Group, delivering social housing, Specialist Disability Accommodation (SDA), and medium-density projects across Victoria and South Australia.
With a strong forward pipeline and long‐term government and community partners, Harnest is focused on predictable delivery, quality outcomes and lasting social impact - building not just projects, but stronger communities.
The Opportunity
We are seeking an experienced Project Manager, in South Australia, to lead the delivery of a portfolio of social housing and Specialist Disability Accommodation (SDA) projects.
You will take full ownership of end‐to‐end project delivery - from pre‐construction and procurement through to completion - ensuring outcomes are commercially disciplined, technically robust and socially meaningful.
Key Responsibilities
* Lead the end‐to‐end delivery of a portfolio of social housing and SDA projects
* Establish and maintain disciplined cost, program, risk and reporting controls across multiple projects
* Manage AS‐based head contracts, variations, EOTs and commercial risk with confidence
* Build trusted relationships with government, client, consultant and authority stakeholders
* Mentor Project Coordinators, Contract Administrators and Site teams, embedding consistent standards and behaviours
* Drive a culture of quality, safety and continuous improvement across the portfolio
* Support resource planning, sequencing and performance reporting to ensure predictable outcomes
About You
* 5+ years' experience as a Project Manager within construction
* Strong working knowledge of AS‐based contracts, regulatory frameworks and compliance requirements
* Commercially astute, with disciplined approaches to cost control, forecasting and risk management
* Confident communicator, able to engage senior stakeholders and provide clear, balanced advice
* A leader who coaches others, raises standards and builds systems that endure
Why Join Harnest
* Join a values‐led construction group, backed by Mazzei Group, with the stability and scale to support complex, long‐term delivery
* Work within a business delivering $100m+ annual turnover with a $150m+ forward pipeline
* Lead meaningful, purpose‐driven projects across social housing, SDA and medium‐density that deliver tangible community outcomes
* Be part of a fully integrated, end‐to‐end business spanning advisory, design and construction - enabling greater control, collaboration and quality
* Step into a role where you are trusted to set standards, influence delivery models and shape how projects are delivered - not simply manage them
* Work alongside experienced, grounded and approachable leaders who are actively involved and genuinely invested in their people
