The Role

We are seeking a Process Engineer for the Process & Hydraulic Engineering discipline for an industrial role in the UK & Ireland.

In this role, you will support the development of robust engineering design solutions under the guidance of senior engineers for water and wastewater infrastructure projects from concept through to construction, commissioning, and operations.

You will support the development of robust engineering design solutions that meet client requirements and contribute to 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 technical skills and gaining early‑career engineering 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 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.

• Assist in ensuring designs incorporate operational, maintenance, lifecycle and whole‑life performance considerations from the outset.
• Prepare design constructability assessments and facilitate the development of safe, practical and cost‑efficient construction methodologies in line with CDM Regulations.
• Provide responsive technical support during construction and commissioning to ensure design intent is correctly implemented and validated.
• Liaise with site teams to address technical issues, update drawings and documentation, and support testing and commissioning activities.
• Conduct site assessments and produce clear engineering reports with actionable recommendations.
• Tools, Systems & Digital Engineering
• Develop, manage and validate intelligent P&IDs, ensuring accurate metadata, tagging and integration with automation/control systems.
• Collaborate with the EICA teams on the relevant CDE (ACC) to ensure control, telemetry and automation requirements are fully represented in design outputs.
• Proficiently use the Microsoft Office suite (Excel, Word, Power Point, Teams, etc.) for documentation, reporting, scheduling and technical analysis.
• Support digital workflows and system integration to enhance design quality and efficiency.
• Training will be provided as needed.
• Continuous Improvement & Business Support
• Support and contribute to tender‑stage design proposals, providing innovative and robust technical inputs.
• Capture lessons learned and support continuous improvement of design processes, tools and standards.
