Overview

Due to continued success and growth across our Water division, we are seeking an
experienced and motivated Design Lead to join our Mechanical Design Team. The
successful candidate will lead multidisciplinary design projects across the island of Ireland.

Reporting to the Mechanical Design Manager, this is a key leadership position responsible for leading the engineering design process, performing technical calculations, making critical design decisions, and developing mechanical system solutions across all stages of project delivery.

This is an exciting opportunity to play a pivotal role in shaping our design capability and mentoring our next generation of engineers, while contributing to the delivery of
industry-leading infrastructure.

Responsibilities

Daily Responsibilities

Develop mechanical engineering design solutions, including system concepts,
process flow arrangements, and equipment configurations for water and wastewater treatment facilities
Perform engineering calculations including hydraulic analysis, pump sizing and
selection, pipe sizing, pressure loss calculations, equipment duty specifications, and system performance modelling
Responsible for leading and managing a team of Design Engineers and Senior
Design Engineers, providing technical guidance, performance management, and professional development
Select and specify mechanical equipment including pumps, valves, actuators, mixers,screens, compressors, and ancillary mechanical systems based on process requirements and performance criteria
Develop technical specifications for mechanical equipment, pipework systems,
materials, and installation requirements
Prepare design basis documents, technical memoranda, and calculation packages to support design decisions
Undertake options analysis and feasibility studies to determine optimal mechanical solutions
Apply engineering judgement to solve complex technical problems and optimize
system performance, efficiency, and maintainability
Liaise with the BIM team by providing marked-up sketches, design intent drawings, redlines, and clear technical instructions on what needs to be produced
Develop P&IDs (Piping and Instrumentation Diagrams) showing process flows,
equipment arrangements, and control philosophy
Provide leadership and direction to design teams delivering water and wastewater
treatment projects
Manage the full design lifecycle – from concept and feasibility through detailed
design, implementation, and handover
Coordinate multi-disciplinary teams (civil, electrical, process, controls) to ensure
integrated design solutions
Coordinating design activities across the project design team to ensure timely
delivery of design information and technical documentation
Act as the key point of contact for clients on technical design matters, supporting
strong relationships and successful project outcomes
Ensure timely delivery of design outputs that meet client, budget, and programme
requirements
Review and approve engineering calculations and technical submissions from the
design team
Review and approve design documentation including mechanical layouts, equipment
specifications, P&IDs, and technical reports
Ensure designs comply with relevant standards, codes (e.g., EN, ISO, BS), and
project quality requirements
Conduct design reviews at key project stages to verify technical adequacy and
constructability
Drive continuous improvement, innovation, and knowledge sharing within the design
function
