With over 40 years of engineering excellence, Hydro International delivers advanced water management solutions that help municipal, industrial and construction customers improve performance, reduce environmental impact and protect communities from flooding and pollution.

• Managing suppliers, subcontractors and internal teams to meet delivery requirements
• Conducting commercial project reviews and agreeing project terms (internal and external)
• Monitoring cost, margin, profitability and performance across assigned projects
• Identifying technical and commercial risks and implementing mitigation plans
• Producing monthly KPI, performance and financial reports
• Identifying and maximising sales opportunities through innovative engineering solutions
• Working collaboratively with engineering, operations, commercial, proposals and delivery teams

About You

You will bring:

• A current, valid UK driving licence
• An engineering background (mechanical or electrical preferred)
• Experience managing engineering or construction‑based projects
• Knowledge of NEC3 / NEC4 contracts (desirable)
• A proven track record delivering projects to challenging deadlines and budgets
• Strong organisational and planning capability across multiple workstreams
• Confident communication skills with the ability to engage customers and stakeholders
• A proactive, collaborative approach and experience leading field‑based teams

Why Join Us?
