We have a talented team of 450 people across Ireland and the UK and are rapidly expanding our workforce across several disciplines to meet our ambitious growth plans.

The Role

We are seeking a Design Lead for the Process & Hydraulic Engineering discipline for a regional role in the UK. In this role, you will play a pivotal part in delivering water and wastewater infrastructure projects from concept through to construction, commissioning, and operations. You will take ownership of developing robust engineering design solutions that meet client requirements and ensure successful project outcomes through to process commissioning.

Working as part of a multi-disciplinary engineering team, you will operate within a collaborative “one-team” culture while actively developing your own technical skills and leadership experience. While your primary focus will be on Process, Mechanical, and Hydraulic Design, you will also engage with and manage inputs and deliverables from other engineering disciplines, including Mechanical, Electrical, Instrumentation, Control & Automation (MEICA), as well as civil and structural engineering.

This role offers exposure to a broad range of multi-disciplinary engineering challenges, providing a strong platform for professional growth and career progression. You will also have the opportunity to develop client relationships, lead design discussions, and contribute to integrated, high-quality project delivery across all stages.
