With a head office in Christchurch, NZ and supporting offices in Australia, Czech Republic and the United Kingdom, Wyma is a truly global company providing innovative solutions for the fresh produce sector in over 50 countries.
With growth and plenty of ongoing and exciting work comes the need for additional people, and in this newly created role, we are looking for a Senior Water Treatment Specialist to be the inhouse subject matter expert to lead the development, specification and compliance of water treatment and recycling systems.
About the role
In this role, you will take technical ownership of Wyma’s water treatment and recycling systems, ensuring they are competitive, compliant, and seamlessly integrated into our broader product offering. You will work closely with engineering, product management, sales, project delivery, and customers to define performance, support delivery, and maintain regulatory compliance, while also playing a key role in testing, standardisation, supplier collaboration, and supporting commissioning, aftersales, and warranty resolution globally.
In particular, you will:
- Assist in the development and strategic evolution of Wyma’s water treatment and recycling product portfolio
- Support and contribute to system and process design, tailoring solutions to meet customer’s needs, including plant layout, P&ID diagrams, chemical treatment systems, and integration of third-party equipment (e.g., RO and UV systems).
- Provide technical support to global sales and project teams during specification, quoting, delivery, and commissioning
- Ensure compliance with relevant national and international standards (AS/NZS, ISO, IEC) and support customers with local regulatory assessments
- Define and validate system performance specifications, operational parameters, and testing programmes
- Develop and maintain technical documentation, specification tools, and training materials
To be successful in the role you will have:
- Tertiary qualification in Chemical, Process, or Civil Engineering, or extensive equivalent practical experience
- Proven experience in water treatment and industrial water systems, including delivering solutions through installation, commissioning, and troubleshooting.
- Strong technical knowledge of water treatment processes (filtration, sedimentation, chemical dosing, disinfection, reverse osmosis) including experience with pump/pipework design, P&ID diagrams, and equipment sizing.
- Exposure to manufacturing environments with experience in quality assurance, testing, and validation processes.
- Excellent analytical, problem-solving, and decision-making skills, with the ability to communicate complex technical concepts clearly.
- Collaborative, customer-focused approach with the ability to work effectively across teams and functions.
The successful candidate will have a strong affinity with Wyma’s core values of Flexibility, Respect, Energy, Sustainability and Honour. We value our staff and provide a generous package including a competitive salary (dependent on skill and industry experience), Healthcare Insurance, and KiwiSaver.
As this role has global coverage there is an international travel component. As such applicants must be the holder of a New Zealand passport. Short-listed candidates will be required to take a pre-employment drug & alcohol screening test.
Here is an opportunity to join a busy and growing team to be the inhouse water treatment subject matter expert. If you have the proven experience in water treatment and industrial water systems, and need a new challenge, let’s talk.
