MB Century – Innovators in Geothermal Technology

At MB Century, we’re proud to be one of New Zealand’s leading geothermal and energy services companies. Our people are problem‑solvers, innovators, and guardians of the environment — and we’re looking for talented individuals who share that purpose.

We are inviting Expressions of Interest from Instrumentation Technicians who are passionate about research, development, and next‑generation downhole technology. If you thrive on technical challenge, hands‑on engineering, and contributing to meaningful renewable energy projects, this is an opportunity to connect with a company shaping the future of geothermal innovation.

About the Opportunity

This role sits at the heart of our R&D and tool‑development work. You’ll support the full lifecycle of our downhole wireline instruments — from concept and design through to testing, calibration, and field commissioning.

The role will:

- Support R&D initiatives to design and improve downhole tools

- Diagnose, repair, and enhance electronic instrumentation

- Build prototypes and validate new designs through rigorous testing

- Develop and modify firmware, embedded systems, and supporting software

- Perform SMT/SMD soldering and electronic board work

- Create and update electrical schematics and 3D mechanical models

- Commission new tools in the field and analyse downhole data

- Collaborate with suppliers, manufacturers, and internal engineering teams

- Manage small R&D projects from concept to delivery

This is a role for someone who enjoys solving complex problems, experimenting with new ideas, and seeing their innovations deployed in real‑world geothermal environments.

Opportunities to Travel and Work Overseas

MB Century supports geothermal operations across New Zealand and internationally. For the right candidate, this role may include opportunities to:

Travel to overseas geothermal fields

Support international tool commissioning

Work with global suppliers and technology partners

Represent MB Century on specialised R&D and field assignments

If you’re looking for a role that takes your engineering skills beyond the workshop and into the world, you’ll find it here.

We’re interested in hearing from people with:

- Bachelor of Engineering (Electronic, Mechanical, or Mechatronics)

- Ideally 5–10 years’ instrumentation engineering experience

- Experience with electronic servicing or engineering environments

- SMT/SMD soldering and fine‑motor precision

- 3D modelling (SolidWorks essential)

- Electronic design (Altium)

- Embedded systems and coding (C, C++, C#)

- Python or SAS scripting

- Strong analytical and problem‑solving skills

- Ability to work outdoors on geothermal sites
