Infravisory is an independent advisory firm dedicated exclusively to water infrastructure delivery. We operate in the space between early approvals and real-world construction, helping clients ensure projects are commercially realistic, buildable, and decision-ready before they go to market.

We combine deep water sector experience with estimator-led, constructability-driven commercial advice and we're growing our team to support that mission.

The Opportunity

This is a junior role within Infravisory's Cost & Commercial Advisory discipline, ideal for someone early in their civil infrastructure career who wants to build genuine estimating and commercial skills on real water infrastructure projects.

About You

You're a civil engineering graduate or early-career professional (0–4 years) with a genuine interest in how infrastructure projects are costed and delivered.

You bring:

- A degree in Civil Engineering, Mechanical Engineering, Process Engineering or equivalent
- Strong attention to detail and a methodical approach to numbers
- Genuine curiosity about construction methodology and cost drivers
- Good communication skills and a willingness to learn from experienced advisors
- Proficiency with Excel; exposure to CostX and Expert Estimator or similar estimating software is a plus but not essential

Applicants must have full working rights in Australia.

Technical Capability

- Advanced experience with CostX, Expert Estimation or equivalent
- Working knowledge of MS Project
- Robust understanding of civil construction methodologies and cost drivers
- Ability to produce structured Basis of Estimate documentation
- Working knowledge of risk modelling tools (highly regarded)

Why Join Infravisory

- Competitive remuneration aligned to advisory impact

We value:

Judgement over process

Commercial realism over theory

Integrity over ego

This role suits a high-calibre infrastructure professional ready to apply delivery experience at a strategic advisory level.

If you are seeking influence, autonomy and meaningful commercial impact in the water sector, we welcome a confidential discussion.
