We're looking for a Sub Agent to join our Thames Water framework team working on our Maple Lodge project, Rickmansworth.

Location: Maple Lodge, Rickmansworth
Hours: 45 hours per week - some flexibility on hours available if desired, just let us know when you speak to us.

We are unable to offer certificates of sponsorship to any candidates in this role.

Join us as a Sub Agent on one of Thames Water's most significant infrastructure upgrades at Maple Lodge Sewage Treatment Works. This major scheme will play a vital role in increasing treatment capacity, improving environmental performance and strengthening long-term resilience for the region. It's an excellent opportunity to take a key delivery role on a high-profile project, helping to coordinate complex civil, mechanical, electrical and process engineering works that will make a lasting difference for customers, communities and the environment.

This is a rare chance to support the safe, efficient and high-quality delivery of a critical section of works on a project designed for the future. You'll help manage programme, engineering coordination, supply chain performance and day-to-day site delivery as major new assets, upgraded treatment processes and enhanced site-wide infrastructure are brought into service.

What will you be responsible for?

As a Sub Agent, you'll be working within the site operations team, supporting them in the successful delivery of wastewater construction works. Your day to day will include:

  • Leading and coordinating day-to-day site operations, ensuring all construction activities are delivered safely, efficiently and according to design specifications
  • Managing subcontractors and direct labour to meet programme milestones, driving performance and accountability across the delivery team
  • Acting as the key point of contact for site-based technical issues, ensuring timely resolution and escalation where appropriate
  • Monitoring progress, recording site data and providing accurate input into project reporting and commercial forecasting
  • Promoting and maintaining adherence to environmental, health and safety legislation, including CDM Regulations

What are we looking for?

This role of Sub Agent is great for you if:

  • You hold an HNC/HND or Bachelor's degree (or demonstrable equivalent experience) in civil engineering or a construction-related discipline
  • You have excellent site management capabilities with sound knowledge of construction methodologies, sequencing and safe systems of work, supported by possession of a valid CSCS card
  • You have strong leadership, organisational and stakeholder coordination skills, with the ability to drive performance on site
  • You have excellent communication and interpersonal skills, with the ability to build effective working relationships across multidisciplinary teams
  • You hold a Full driving licence to facilitate travel across project locations

We're all about finding potential here at Kier, and transferrable skills are always welcome! So, even if you don't tick every box, please apply and we can have a chat.
