Job description

Jora New Zealand will close on 9th September 2026. Thank you for being with us, we are cheering you on as you continue your career journey.

Lead complex infrastructure projects. Develop great people. Help shape the future of Seipp in the lower North Island.

At Seipp Construction, we're delivering infrastructure that makes a real difference to communities across New Zealand.

As an award-winning nationwide contractor, we're known for tackling technically challenging infrastructure projects and delivering them safely, collaboratively and to an exceptionally high standard. From complex civil works and structures through to mechanical installations, water and wastewater infrastructure, pump stations and specialised industrial projects, we pride ourselves on doing the job properly and building lasting relationships with our clients.

As our presence across the lower North Island continues to grow, we're looking for an experienced Senior Project Manager or Project Manager to join our Wellington team.

You may already be an established Senior Project Manager or Project Manager, or perhaps you're a high-performing Senior Project Engineer who's ready to take the next step. What matters most is your ability to lead projects commercially, technically and operationally while helping us continue to build our capability and reputation throughout the region.

About the Role

This is much more than a project delivery role.

You'll take ownership of projects from tender handover through to successful completion, balancing commercial performance, programme delivery, client relationships and team leadership.

We're looking for someone who is equally comfortable reviewing contract conditions, forecasting project costs, managing project financial performance, negotiating with subcontractors, mentoring engineers and spending time on site ensuring work is delivered safely, efficiently and to a high standard.

You'll join a growing Wellington team delivering complex infrastructure projects across the lower North Island. Current work includes Seipp's recently awarded $5.2 million Carterton District Council Headworks Upgrade at the Carterton Wastewater Treatment Plant, together with a major New Zealand Defence Force fire protection upgrade at Ohakea. The Ohakea project includes replacing the existing deluge tank and upgrading firefighting systems, fire water storage and pump infrastructure, hydrants, drainage and containment systems across multiple operational facilities. With a strong pipeline of work continuing to develop across the region, you'll play an important role in shaping Seipp's future in the lower North Island.

What You'll Be Doing

• Lead projects from tender handover through to successful completion
• Manage project budgets, forecasting, cost control, variations and claims
• Administer contracts and protect Seipp's commercial position
• Build trusted relationships with clients, consultants and key stakeholders
• Manage subcontractors to achieve quality, programme and commercial outcomes
• Lead, mentor and develop Project Engineers, Site Engineers and site teams
• Drive a strong safety culture where quality, planning and delivery go hand in hand
• Identify project risks early and implement practical solutions
• Support the continued growth and reputation of Seipp throughout the Wellington region

What We're Looking For

Successful projects don't happen by accident. They require strong leadership, sound commercial judgement and people who genuinely understand how projects are built.

You'll ideally bring:

• Proven experience delivering complex civil infrastructure projects
• Strong commercial and financial management capability
• Excellent understanding of NZ construction contracts and contract administration
• Experience managing subcontractors across multiple disciplines
• A practical understanding of construction, not just project management
• Broad experience across civil construction, with exposure to concrete structures, drainage, mechanical installations and structural works highly regarded
• Strong planning, problem-solving and decision-making skills
• Excellent communication and relationship-building skills
• A genuine passion for mentoring and developing others
• A collaborative leadership style with a focus on achieving the best outcomes for clients, projects and teams

Experience delivering complex civil infrastructure projects is essential. Experience within water and wastewater treatment, pump stations or process infrastructure would be advantageous, but is not essential. We're interested in capable project leaders from a broad range of infrastructure sectors who are looking to make an impact.

Why Join Seipp?

Seipp combines the technical capability, systems and expertise of a major contractor with the agility, flexibility and self-perform capability of a proven Tier 2 business. Our ability to self-perform much of our work gives us greater control over quality, programme and outcomes for our clients.

We're not looking for someone to simply manage projects. We're looking for someone who wants to help build our Wellington business, develop our people and leave a lasting impact on the communities we work in.

We're also committed to developing our people through leadership programmes, mentoring and clear career pathways because we know our future success depends on building great leaders, not just delivering great projects.

When you join Seipp, you'll enjoy:

• Competitive salary package
• Company vehicle
• Flexible working arrangements, including hybrid working where project commitments allow
• UniMed Health Insurance after 90 days, including cover for pre-existing conditions
• Ongoing professional development and support towards industry accreditation
• Clear career pathways and opportunities to continue growing your career
• A supportive team culture that values collaboration, innovation and doing things properly
• The opportunity to play a key role in shaping Seipp's continued growth across the lower North Island

Ready to Make a Difference?

This is an opportunity to become a key leader within a growing business.

You’ll help deliver meaningful infrastructure projects while mentoring the next generation of engineers and project leaders, strengthening client relationships and contributing to the continued growth of our Wellington business.

If you're looking for a role where you can combine commercial leadership, technical delivery, team development and relationship building while working on projects that make a real difference, we'd love to hear from you.
