Control Systems Engineer - Lead

Mint Innovation has been developing innovative cleantech since 2016. Our mission is to provide low cost, sustainable solutions to recover valuable metals from waste (the urban mine) via plants in major cities around the world.

Headquartered in Auckland, Mint has established a project management office in Sydney to manage the build of our first electronic waste recycling facility in Smithfield. Following this will be a roll-out of further plants internationally. The plants will use the latest technology, as well as proprietary chemical and biological processes to recover base and precious metals (e.g. copper and gold) from electronic waste. For more details, see our website.

Why Apply?

This is a rare ground floor opportunity to join a tight-knit team and lead plant automation at a growing cleantech startup.  You will have a large degree of autonomy in developing and overseeing the implementation of the control systems for our new e-waste processing plant. With a competitive salary plus super, flexible/remote working arrangements and access to our employee share option programme, you’ll also have the opportunity to further your career as we expand internationally and grow our team.  

The Role

Based in either our Engineering HQ in Auckland or at our Project Management Office in Sydney, you will be responsible for taking this plant automation project all the way from procurement through to commissioning. The decisions made here will bake in our automation stack for the deployment of future plants around the world, so choose wisely! Mint will task an automation firm to do the heavy lifting, but we will require your steady hand to help oversee and manage the contractors to keep the project on time and in budget. You will be expected to obtain a deep knowledge of Mint’s process so that you can identify and solve process control problems as they arise, and be able to provide hardware and software support for our Sydney plant in its commissioning phase.

Travel will be required (COVID-willing); if Auckland based, plant commissioning is scheduled for early 2022, so you’ll be onsite in Sydney for several weeks at a time. If Sydney based, you’ll spend time in Auckland getting to know our Engineering team and process. We aim to be as flexible as possible for the right candidate. 

Skills and Experience

This is an opportunity for someone to use innovative control methods and technologies to make our plant sing. We want someone who has a bias for action, a strong sense of urgency when it comes to solving problems - and someone who doesn’t get discouraged when setbacks occur (we are a start-up after all!). Our ideal candidate will have as many of the following qualities as possible:

  • 5+  years experience in automation of process plants that deal with solids & liquids (e.g. chemical/food & bev/waste water)

    • Experience in commissioning plants is essential

  • Degree qualified in a relevant subject (electrical/mechatronics engineering) preferred

  • Highly proficient in control system design, programming, configuration, and commissioning

    • We are currently considering Siemens or Allen Bradley as PLC brands; Inductive Automation Ignition or Siemens WinCC for SCADA/HMI

    • SQL database admin experience desirable

  • A knack for interpreting functional descriptions, identifying automation design risks and providing solutions

    • Ability to read pneumatic & hydraulic schematics is a big plus

  • Oversight experience of automation/electrical contractors so we achieve maximum value for money on our projects

  • Troubleshooting talent for basic electrical/instrumentation issues and automation systems

  • Knowledgeable in industrial safety systems, standards, and verifications

  • Comfortable with the start-up life: working in a fast-paced team to hit deadlines

We’re aiming to quickly shortlist and interview candidates over the course of September to start ASAP. 

Please note you must have the right to work in Australia or New Zealand to apply for this job. Regrettably we will not be offering visa sponsorship to relocate.


Mint Summer Internships (2021-22)


These  internships will run for 10 weeks, 40 hours per week based at Mint Innovation's office/labs in East Tamaki, Auckland. Start date is flexible, but sometime in November or December would be preferable.

Chemical Intern

A suitable chemistry student, ideally concluding their final year of undergraduate studies or in the process of their Master of Science will get a crash course in Mint’s chemical and bio-metallurgical processes while they support our scientists on a new research project (TBC in October). Once proficiency is demonstrated, the student will be given more autonomy and will likely contribute to other R&D projects as they arise.


Process Engineering Intern

Two suitable engineering students (process/mechanical/chemical), ideally concluding their penultimate or final year of undergraduate studies, will assist our engineering team as Mint's commercial plant (Sydney) enters its build phase. This will involve addressing issues as they arise through making P&ID updates, editing process and functional descriptions, consulting with equipment vendors and drafting commissioning documentation. In addition, the students will have exposure to the operation and maintenance of our existing demonstration plant.


Business Development Intern

A suitable business/commerce student, ideally concluding their penultimate or final year of undergraduate studies, will assist our business development team which would also include working with the CEO and our UK team. Potential projects include techno-economic analysis, market research, to several digital marketing aspects such as website design and handling of the company’s social media channels, and also help with company financials.

No other current openings

Although we don't have any dedicated roles that we're looking to fill at this time, as a start-up we're always interested to hear from entrepreneurial scientists with experience in inorganic chemistry, bioremediation, biotechnology or metallurgy in general. The same goes for chemical and process engineers, so please feel free to introduce yourself to us!
