Murphy is recruiting an Senior Project Engineer to support our expanding Water & Wastewater portfolio, delivering full design‑to‑operation solutions for Uisce Éireann, Northern Ireland Water and other key clients, underpinned by our commitment to delivering safely, responsibly and to the highest standards.

We are looking for a technically strong Senior Project Engineer to provide specialist engineering input and technical leadership on complex clean water and/or wastewater infrastructure projects, and sludge treatment and bioresources. This role focuses on the detailed technical aspects of project delivery — including design development, optioneering, technical assurance, and problem resolution — supporting the UK water sector’s AMP investment programmes. You will work as a key team member within multi-disciplinary teams, ensuring schemes meet regulatory, safety, performance, and sustainability standards.

What You Will Be Doing

• Develop and optimise technical designs for water and wastewater projects, including treatment works upgrades, network reinforcements, pumping stations, process improvements, and sludge treatment facilities.
• Lead technical optioneering, hydraulic and process modelling, scheme appraisals, and detailed engineering calculations from concept through to construction‑ready stage, with input on sludge handling processes.
• Provide high‑level technical assurance and review of designs, specifications, drawings (including P&IDs), and contractor submissions.
• Resolve complex technical queries and engineering challenges during design, construction, and commissioning phases.
• Ensure compliance with relevant standards, regulations (e.g., DWI, EA, Ofwat), CDM 2015, company engineering specifications, and health & safety requirements.
• Support site‑based activities, including technical site inspections, testing (FAT/SAT), commissioning oversight, and handover documentation.
• Collaborate closely with design teams, contractors, and stakeholders to integrate MEICA (Mechanical, Electrical, Instrumentation, Control & Automation) elements effectively.
• Contribute to innovation, digital delivery (BIM, GIS), sustainability initiatives (including net‑zero and bioresource optimisation), and value engineering from a technical perspective.
• Prepare and review technical reports, briefs, risk registers (technical elements), and assurance documentation, with focus on sludge process performance and environmental compliance.

Who We Are Looking For

• Degree (or equivalent) in Mechanical, Electrical, Chemical, Process, or Environmental Engineering (or closely related discipline).
• Minimum 6–8 years’ relevant post‑graduate experience in the UK water industry, with strong technical delivery on capital projects (clean water, wastewater treatment, or infrastructure), including demonstrable knowledge and experience of sludge treatment processes.
• Sound knowledge of water/wastewater processes, hydraulic design, sludge treatment technologies and industry standards/regulations.
• Experience of technical design development, optioneering, and assurance processes
• Understanding of CDM 2015 and health & safety in a construction/environmental context (IOSH Managing Safely or equivalent).
• Working towards or holding Chartered Engineer (CEng) status with ICE, CIWEM, IMechE, IChemE, or IET.
• Experience across AMP programmes and with major water utilities or consultancies, particularly in bioresources and sludge optimisation.
• Familiarity with MEICA systems, process safety, hydraulic/process modelling tools, BIM Level 2, and digital engineering applied to sludge facilities.

What You Will Get In Return

• 27 days holiday, plus bank holidays with the option to buy an additional 2 days holiday each year, holidays increase with length of service
• Discretionary annual bonus and annual salary review
