Technical officer (spill and flow)

If you enjoy solving problems, working with data, and making a real impact on wastewater performance and the environment, this role is for you.

We’re looking for a Spill and Flow Technical Officer to take the lead on how we manage, monitor, and improve our flow and spill assets. You’ll join a dedicated team of Technical Officers, forming a key part of the wider Systems Performance Team. This structure gives you real ownership of your area, close collaboration with colleagues, and the opportunity to become a recognised expert in flow and spill performance.

You’ll work closely with operational teams, using your technical knowledge to keep our assets compliant, efficient, and performing at their best.

This isn’t a desk-only role. You’ll split your time between analysing performance trends, interpreting operational data, influencing decisions, and getting hands-on out on site. You’ll also have the autonomy to plan your own working day by prioritising site visits, investigations, data analysis, and operational support in the way that works best for you.

In this role, you’ll have real ownership over your area. You’ll:

• Turn operational data into clear insights, spotting risks early and driving corrective action.
• Work closely with regional teams to make sure all flow and spill sites meet environmental and regulatory standards.
• Carry out site inspections and investigations to identify the causes of spills and find practical solutions.
• Provide accurate, high-quality data for regulatory submissions and communications with the Environment Agency.
• Support and challenge operational teams to maintain safe, reliable, and efficient processes.
• Ensure telemetry alarms are fit for purpose to identify potential non-compliant spills.
• Share your expertise through coaching, training, and promoting best practice across the team.

This role may not be eligible for sponsorship.

• Strong data analysis skills and the ability to interpret data and trends

• A solid understanding of flow and spill assets, including their operation and maintenance.
• Experience of EA regulations and permits

• True autonomy to plan your own day, balance site and office work, and shape how you deliver results.
• A role that’s never dull, from site investigations to data analysis, you’ll have real variety and hands-on problem-solving every week.
• A dedicated work van to support your travel from different locations.
• Flexibility on where you’re based.
• Ongoing development and learning, with access to a highly experienced wastewater treatment and network performance team.
• The chance to make a meaningful environmental impact, improving river health, customer outcomes and regulatory performance.
