Who We Are…

At Pennon, Digital & IT plays a critical role in keeping essential services running safely, securely and efficiently. Our Operational Technology (OT) and SCADA systems underpin the day‑to‑day operation of water and wastewater treatment works, pumping stations and networks across the Southwest.

These systems allow our operational teams to monitor, control and protect vital infrastructure in real time. From treatment works and pumping stations to remote assets, our Digital & IT teams help ensure services are reliable, resilient and secure.

As a graduate joining our Digital & IT function, you’ll work at the intersection of technology and real‑world operations, learning how industrial systems, data and cyber security come together to support essential services that protect public health and the environment.

What You’d Be Doing…

This graduate role places you within our Digital & IT teams, gaining hands‑on experience across Operational Technology, SCADA and industrial control systems that support wastewater and clean water operations.

As a Digital & IT Graduate (OT & SCADA), you could:

- Support the configuration, testing and commissioning of SCADA systems used to monitor and control operational assets

- Help integrate control systems such as PLCs, RTUs and telemetry into wider monitoring platforms

- Assist with alarm configuration, data trending, reporting and visualisation to support operational decision‑making

- Work alongside engineers to diagnose faults and support live operational systems safely

- Contribute to OT cyber security activities, system hardening and standards compliance

- Support projects that improve system resilience, consistency and performance

- Build an understanding of how Digital & IT underpins water and wastewater treatment processes

You’ll rotate across different Digital & IT and operational teams, giving you exposure to both project delivery and day‑to‑day operational support.

Who You Are…

We’re keen to hear from graduates who are curious about technology, enjoy problem‑solving, and want to understand how digital systems operate in real‑world, safety‑critical environments.

You’ll Also Need

Don’t worry if you don’t tick every box. You won’t be expected to arrive with all the answers, curiosity, motivation and a willingness to learn matter most.
