Senior Environmental Scientist

Ready to take your contaminated land career to the next level?

Join AECOM’s established Contaminated Land team in Hamilton as a Senior Environmental Scientist and work alongside some of the industry’s leading environmental professionals on projects that are varied and technically challenging.

From major multi-disciplinary transport alliances and closed landfill assessments through to preliminary and detailed site investigations, you’ll have the opportunity to broaden your technical expertise while working across a diverse project portfolio.

You’ll be part of a collaborative team with access to AECOM’s local and international technical leaders, giving you the support, expertise and opportunities to keep developing your career.

And this role isn’t just about the technical work. As you grow, you’ll have opportunities to move into project management, client relationship development and business development, including a structured training programme to help you build your project management capability.

What you’ll be doing

• Plan and deliver contaminated land investigations, including PSI/DSI, sampling programmes and fieldwork.
• Undertake and oversee soil, groundwater, surface water and vapour/gas sampling and monitoring.
• Interpret field and laboratory data and prepare technical assessments, risk assessments and reports.
• Manage field teams, subcontractors and laboratories to deliver investigations safely, efficiently and to programme.
• Contribute to project scopes, methodologies, fee estimates, proposals and tenders.
• Take responsibility for technical delivery, work directly with clients and provide guidance to graduates and early-career environmental scientists.

What you’ll bring

• A Bachelor’s or postgraduate degree in Environmental Science, Geology or a related Earth Science or Science discipline.
• Ideally 5+ years’ experience in contaminated land, environmental site assessment (PSI/DSI) and/or remediation.
• Strong practical field skills, including sampling and monitoring of soil, groundwater, surface water and vapour/gas.
• The ability to plan, coordinate and deliver high-quality technical work with minimal supervision.
• Experience moving comfortably between large multidisciplinary projects and smaller, focused commissions.
• A proactive, solutions-focused “can-do” attitude and the curiosity to keep learning.
• Strong communication and collaboration skills, with the confidence to work with clients and colleagues at all levels.
• A willingness to travel across New Zealand — a full NZ driver licence is essential.
• Experience with Excel is expected; familiarity with ArcGIS and ProUCL would be advantageous​​​​Why AECOM?

This is an opportunity to join a team where you can build on your technical expertise, broaden your project experience and shape the next stage of your career.
