Senior Process Engineer and Process Engineer

ARE YOU READY TO TAKE THE NEXT STEP IN YOUR ENGINEERING CAREER?

We’re looking for two talented Process Engineers—one senior and one intermediate—to join our team at Apex Water.

Whether you’re an experienced leader in process design or an engineer ready to take on more responsibility, this is your opportunity to work across diverse projects in the water and wastewater sectors, making a real impact for our clients and communities.

Apex Water specialises in the design and construction of water and wastewater treatment plants. Through our design, build, installation and commissioning capabilities, we help New Zealand grow sustainably while protecting the environment for future generations. Our approach brings projects together through one point of accountability, working with some of New Zealand’s most well-known companies across the municipal, dairy, food and beverage sectors.

The success of Apex Water is its people! We value trustworthiness, initiative and a practical “can do” attitude. Our close-knit team shares knowledge, supports one another and takes pride in delivering quality work. Guided by our values—Bold, Passionate, Trustworthy and Protect what matters—we welcome fresh ideas, follow through on our commitments and look after our people and the environment. We enjoy working together and having fun along the way.

Both roles are full-time and permanent. We welcome candidates based in either Auckland or Christchurch. Occasional travel to project sites is required.
