Deliver New Zealand cleantech innovation to a global market

Cetogenix is a New Zealand cleantech company developing a proprietary waste transformation platform – Ceto-Boost™ - that unlocks the energy and nutrient potential of complex organic residues.

Formed in 2022, Cetogenix has completed a range of NZ- and UK-based pre-commercial assessment and prototyping projects that have reinforced our compelling vision to deliver globally impactful energy resilience and waste circularity.

The company is now moving to broader system scale-up and acceleration of commercial deployment, including entering the build phase of our next generation modular plants with domestic and international in-market demonstration and first-of-a-kind (FOAK) commercial deployment to follow.

To this end, the company is seeking to increase its technical resourcing capacity by recruiting for the following roles:

·        Mechanical Design Engineer

·        Process Engineer

·        Technical Officer

·        Casual Laboratory Technician

This is an ideal opportunity to join a New Zealand deep technology company as it moves toward novel infrastructure design and fabrication, commercial readiness, and further IP development, laying the foundation for long-term growth and environmental impact across multiple geographies and sectors.

Mechanical Design Engineer

Our Mechanical Design Engineer will lead all mechanical aspects of our Ceto-Boost™ plants. Specific elements of the role will include design of high-pressure, advanced thermal conversion systems, modularisation, and development of robust, repeatable hardware solutions suitable for commercial deployment.

We are looking for an engineer with strong industrial processing experience who is motivated to turn innovative engineering concepts into reliable, market-ready infrastructure.

You will work closely with external fabricators and engineering partners to translate process requirements into robust, manufacturable hardware. You will see your designs fabricated, installed, and commissioned in real-world operating environments.

This full-time role is based in Rotorua but will require occasional domestic and international travel to support fabrication oversight, installation and commissioning activities.

Process Engineer

We are seeking a Process Engineer to lead process optimisation and engineering integration in a role that sits at the centre of our technology scale-up. You will own process modelling, translate pilot data into deployment-ready engineering inputs, refine system performance, and validate assumptions critical to commercial rollout.

We are looking for an experienced process or chemical engineer with specific skills in high-pressure or thermal systems, strong modelling capability, & practical commissioning experience.

You will work closely with our internal and external fabrication and project delivery teams to ensure our Ceto-Boost™ systems meet design specifications and performance targets.

This full-time is based in Rotorua but will require occasional domestic and international travel to support installation, commissioning and performance monitoring activities.

Technical Officer

Our Technical Officer will coordinate day-to-day pilot-plant and field trial operations to ensure efficient and high-quality experimental delivery in support of Ceto-Boost™ development. You will also oversee the company’s health and safety activities.

With a science or engineering background, this is a hands-on role requiring a practical, safety-focused mindset driven by a desire that our modular systems are operated and maintained to a high standard. An ability to be flexible, innovative and multi-talented will be key to your success.

You will work closely with our internal and external fabrication and project delivery teams to ensure our Ceto-Boost™ systems are safe, compliant, and operationally robust.

This full-time is based in Rotorua but will require domestic and international travel to support installation, commissioning and performance monitoring activities.

Casual Laboratory Technician

This is a hands-on role contributing directly to laboratory activities as scale-up and deployment progresses. You will conduct analytical testing, support hydrothermal and biological experiments, assist with pilot plant sampling, and ensure accurate, high-quality data collection and reporting.

We are looking for a methodical, safety-conscious laboratory professional with experience in chemical, biological, or environmental systems. Attention to detail, strong practical skills, and the ability to work both independently and within a multidisciplinary technical team are essential.

You will work closely with our project delivery teams to ensure optimal operational performance of Ceto-Boost™ systems through effective experimental design and performance assessment.

This casual role is based in Rotorua but will require occasional domestic travel to support sample collection and performance monitoring activities.
