I’m working with a major civil engineering contractor delivering high-profile infrastructure works across water, energy, and environmental sectors. Due to a strong secured pipeline, they’re now looking to appoint a Design Manager to join their team in Hertfordshire, overseeing key AMP8 water projects.

• Ensuring designs meet technical, regulatory, and operational standards.
• Supporting project teams by coordinating design interfaces and resolving site-based engineering queries.
• Driving technical compliance, risk mitigation, and design quality throughout the lifecycle of each scheme.

What we’re looking for:

• Strong civil engineering background with 10+ years’ experience in design and design management.
• Proven ability to lead design on complex water or infrastructure projects.
• Knowledge of potable and foul water networks, drainage, temporary works, and BIM processes.
• HNC/Degree-qualified and ideally working toward or already holding Chartered or Incorporated Engineer status.
• Strong stakeholder engagement skills and commercial awareness of delivering against programme and budget.

What’s on offer:

• Salary up to £80,000 depending on experience.
• Full package including car or allowance, private medical, enhanced pension, life assurance, and more.
• Long-term framework work, career progression, and a real emphasis on internal development.
