As a multidisciplinary consultancy, we combine technical expertise, creativity, and integrated delivery to lead complex, mission-critical projects.

Sustainability guides how we design, collaborate, and deliver, creating innovative solutions and lasting value for our clients and communities — making Performance Made Possible.
About the Job
As a Senior Building Services Engineer, you will lead the delivery of mechanical building services/ MEP design for energy, industrial and commercial projects within a multidisciplinary building services consultancy environment. The role focuses on the design of base-build and building services systems for complex and regulated facilities, rather than process or manufacturing equipment design.
You will manage the full project lifecycle from concept through to client handover, build strong client relationships, and mentor engineering staff to ensure all deliverables meet the required technical and quality standards.
This is a hybrid role based in Ireland, with attendance at the Dublin office aligned to team and project requirements.
Responsibilities
Lead mechanical building services design on energy, industrial and commercial projects from concept stage through to completion
Represent Ethos at Client and Design Team Meetings
Deliver mechanical services solutions for buildings, including manufacturing, food and beverage, pharmaceutical, medical devices, life sciences, laboratories and commercial developments

Develop mechanical services designs for ATEX-classified environments, cleanrooms and laboratories, coordinating closely with safety and compliance requirements
Coordinate mechanical building services designs with architectural, structural, electrical, process and client stakeholders
Carry out continuous design and installation quality checks to ensure compliance with project specifications and applicable standards
Prepare fully detailed mechanical building services tender packages, technical reports, analyses and recommendations
Support construction stages through technical queries, site visits and coordination with contractors and vendors
Take technical ownership of projects, operating with minimal input from senior management
Mentor, guide and review the work of junior and intermediate engineers, ensuring QA standards are met prior to issue
