This role is predominantly office-based, where you’ll provide strong technical leadership and design input across the project lifecycle, with site visits and construction observation undertaken as required. You’ll work alongside a highly qualified, talented, and passionate multidisciplinary team delivering complex water and wastewater infrastructure projects across Aotearoa.

The successful applicant will:

• Build strong, open relationships with clients, contractors, suppliers, and internal teams to support successful project outcomes
 
• Co-ordinate closely with mechanical, electrical, and process disciplines to ensure integrated, buildable design solutions.
• Identify and manage design risks, constructability issues and discipline interfaces early in the design process.
• Ensure all engineering deliverables meet required quality, regulatory, and New Zealand standards.
• Provide technical guidance and support to project teams, including mentoring junior engineers and designers.
• Support construction activities through technical input and construction observation when required.
• Maintain accurate, complete, and up-to-date design documentation, calculations and reports.
• Participate in design reviews and continuous improvement initiatives to improve future project delivery.

We want someone who:

• Holds a degree in civil engineering or a related discipline (BE or equivalent).
• Has 7+ years’ relevant experience delivering civil design from concept through to detailed design.
• Brings strong experience in earthworks, drainage, and utility design, ideally within water or wastewater infrastructure.
• Has experience coordinating civil and structural designs with mechanical systems, plant, and equipment.
• Has a solid understanding of the end-to-end project lifecycle, with a strong focus on design delivery and technical assurance.
• Is well-versed in civil construction principles and understands how designs translate to site.
• Communicates  learly and confidently across disciplines, with strong analytical and problem-solving skills.
• Is comfortable working independently while contributing positively within a collaborative team environment.
• Is willing to travel to project sites as required.
• Is passionate about delivering high-quality outcomes for clients and enjoys working with a team that takes pride in what they do.

What we offer:

At Apex Water, you’ll be part of a dynamic, inclusive team that values innovation, collaboration, and making a real difference to New Zealand’s sustainable future.
