Why Join

  • Direct Influence: You won't just be a technical reviewer; you will be the architect of our coastal division. You define the standards, choose the tech stack, and set the technical direction.
  • Mastery of PC120: We are positioning ourselves as the "go-to" for navigating the new Plan Change 120 requirements. You will lead the charge in helping clients understand the immediate legal effects on coastal erosion and inundation hazard areas.
  • Zero Red Tape: We operate with a flat structure. Decisions are made in minutes, not months. If you have a vision for how coastal engineering should be delivered, you have the green light to execute it.

  • PC120 Navigation: Act as the subject matter expert on Auckland Council’s new risk management framework, helping clients move through the shifted activity classifications (Sensitive vs. Less Sensitive) and new sea-level rise (SLR) modeling requirements.
  • Strategic Mentorship: Build a high-performing team from the ground up, mentoring the next generation of engineers in coastal processes and climate change adaptation.
  • Client Advocacy: Act as an expert witness and lead consultant on high-stakes coastal developments, representing the firm at the highest levels.

What you Bring

  • The Experience: ~15 years in Coastal Engineering, with a significant portfolio of work in the New Zealand coastal environment.
  • Regulatory Expertise: A deep, working knowledge of the Auckland Unitary Plan, the NZCPS, and specifically the implications of PC120 on coastal erosion and inundation overlays.
  • Technical Breadth: Proficiency in coastal modeling (DHI/MIKE, SWAN, etc.) and a practical understanding of seawall, revetment, and nature-based solution design.
  • The Credentials: CPEng status is essential. You should be comfortable providing high-level technical sign-offs and peer reviews.
  • The Startup Mindset: You are a "player-coach"—someone who loves the deep technical work but is equally excited by the challenge of building a brand and a team.

Skills Required

  • Stormwater Management
  • Catchment Planning
  • Design
  • Flood Assessments
  • Green Infrastructure

The Package

  • Salary:  A competitive salary, negotiated to reflect experience and impact.
  • Autonomy: A workplace built on trust, results, and the flexibility to work in a way that suits your life.

Job Overview

Are you a flood modeller with a strong technical base who wants real ownership of their work, not just a small piece of a large corporate machine?


This is an opportunity to join an agile, NZ-owned engineering consultancy at a key growth stage. We are looking for a senior technical modeller to act as the backbone of our flood modelling capability, someone who wants to help build how the business works, not just deliver outputs.


In this role, you will be the lead flood modelling resource, responsible for driving the technical direction of projects from start to finish. You will have the autonomy to set modelling approaches, develop and refine tools and standards, and play a hands-on role in shaping our systems and mentoring future team members as we grow.

Why Join

  • Total Tooling Control: You will not inherit outdated legacy models. You help decide how we build models, which software we invest in, and how data is structured and delivered.
  • Agility & Freedom: Low bureaucracy and a strong bias toward action. If there is a better way to run a model, test a scenario, or visualise a catchment, you are trusted to implement it.
  • Direct Growth Path: Progression is driven by contribution and impact, not time served. As the business grows, there is a clear pathway to lead and shape our modelling capability.
  • Meaningful Projects: Work on complex, high-quality infrastructure projects across New Zealand, with the autonomy and flexibility that comes from a focused, modern consultancy.

Your Impact

  • Technical Ownership: Develop and manage complex 1D and 2D hydraulic and hydrological models for urban and catchment-scale projects, with strong capability in TUFLOW, InfoWorks ICM or Hec-RAS.
  • End-to-End Delivery: Take responsibility for the full modelling workflow, from data assembly and boundary conditions through to flood hazard mapping and technical reporting.
  • Strategic Advisory: Ability to translate modelling outputs into clear, practical advice that supports clients, planners, and design teams in making sound decisions.
  • Technical Leadership: Act as the technical authority for flood modelling, ensuring all outputs meet best-practice New Zealand standards, including relevant Council codes and guidance.

What You Bring

  • 5 - 10+ years of experience in hydraulic modeling within the New Zealand market.
  • Autonomy: You are at a point in your career where you can troubleshoot technical hurdles and produce high-quality models with minimal oversight.
  • The Startup Mindset: A self-starter who enjoys the pace of a growing business and wants a role where their contribution is visible, valued, and influential.

The Tech Stack

  • We are looking for a versatile modeller who is comfortable working across a range of industry-standard platforms. You should have strong capability in some of the following:
  • Stormwater Modeling: TuFLOW, InfoWorks ICM, DHI (MIKE Suite), and HEC-RAS.
  • Spatial Analysis: QGIS or ArcGIS for data management, analysis, and flood mapping outputs.

The Package

  • Salary: A competitive salary, negotiated to reflect experience and impact.
  • Autonomy: A results-focused environment that values trust, flexibility, and accountability over hours at a desk.
  • Culture: A small, values-led team where you play a key role in shaping the business, not just filling a position.
