We have a fantastic opportunity for you to join Thames Water as a Senior Technician based at our wastewater treatment at Slough.

As our Senior Technician, you will provide flexible cover to support the existing operation teams, depending on resource needs and priority. This is a great opportunity for someone ambitious, wanting to help lead a team to success and take that next step towards management.

In this role, there will be plenty of opportunities to take ownership of various project work to get stuck into. You will be writing working procedures and instructions, involved in H&S improvements, meeting contractors, raising quotes and bringing an array of new, fresh ideas to the table to improve processes.

Utilising your experience on the sewage treatment works, you will take the lead role in key field‑based activities, along with supporting the Performance Manager in managing and coordinating a team of technicians on the site.

Responsibilities

• Provide coaching and mentoring for team members, including apprentices, upskillers and new starters (for example, Tech 1 training, monitor verification processes, event learning).
• Provide technical input to help with the delivery of the maintenance plan and promote first‑time fixes (including attending planning meetings, inputting into asset availability improvements, and investigating site trips).
• Work with the performance managers to assist with the smooth running of the team by taking over some day‑to‑day management or coordinating activities (for example, assisting with process risk assessments, obtaining quotes, assisting with site inductions and reviewing RAMS).
• Role‑model positive behavioural safety and site pride. Support and promote a positive H&S culture (for example, supporting your colleagues to recognise and raise safety observations, own resolution of issues, identify ‘Site Pride’ sites, assist with H&S action completion).
• Step up to help cover activities when the performance manager or technical coordinator is unavailable.
• Participate in out‑of‑hours standby rota.
