About Paebbl

Paebbl is an industrial resilience company turning captured CO₂ into carbon-storing building materials. We accelerate the natural process of CO₂ mineralisation — in which CO₂ reacts with minerals to form stable carbonates from thousands of years — to a matter of hours, producing a carbon-negative powder that can replace conventional, heavily emitting cementitious materials. Having switched on the world's first continuous CO₂ mineralisation demonstration plant, we are now scaling from startup execution into structured industrial operations. It is a fast-moving environment where pragmatism, ownership, and the ability to build things that work in the real world matter.

The Role

This is a hands-on, on-site role for someone who is comfortable being the go-to person for IT and OT support in a fast-moving environment: practical, self-sufficient, and happy to own the day-to-day work that keeps a site running.

Paebbl needs on-site cover for IT/OT support, administration, and networking. Much of this work is hands-on and cannot be done remotely — device admin, networking, and day-to-day support all need someone physically present. This is a fixed-term hire to cover that work directly and keep things running smoothly on-site.

As IT/OT Support Engineer, you will take on the bulk of day-to-day IT support, handle device and software administration, and provide networking and OT/security support where needed. You will be the person people turn to when something is not working, and the one who keeps the site’s systems steady. This is a 4 month contract role, with opportunity for extension.

Key Responsibilities

Day-to-Day IT Support

• Provide day-to-day IT support on-site — the bulk of the role.

• Respond to and resolve support requests directly, keeping people productive.

Device and Software Administration

• Administer devices and software, including setup, configuration, and maintenance.

• Keep systems and equipment in good working order across the site.

• Proactively seek opportunities for improvement and automation

Networking and OT/Security

• Support networking on-site, an area where we currently have less in-house depth.

• Provide OT and OT/security support where needed.

What We’re Looking For

• IT support experience, plus device and software administration — this is the main part of the role and the core requirement.

• Able to work independently and hands-on, on-site.

• Comfortable owning day-to-day support and being the on-site point of contact.

Nice to Have

• Networking experience — a strong plus, as it is an area where we have gaps and less direct experience in-house, so it adds real value.

• OT and OT/security experience — also a strong plus, for the same reason.

• Experience supporting an industrial, manufacturing, or operational site.

The Person Who Will Thrive in This Role

You will likely succeed in this role if you are practical, dependable, and comfortable being the only on-site IT/OT person for much of the day. You do not wait to be told what to do — you see what needs fixing and get on with it. You are happy handling the basics well and confident enough to take on networking and OT/security work where it is needed.

You bring low ego, a strong sense of ownership, and the kind of steady reliability that lets the rest of the team get on with their work knowing the site is in good hands.
