About Ethos

Ethos is a collaborative team of engineers, consultants, and creative thinkers designing and delivering data centre and energy infrastructure across the world's most dynamic markets. As a multidisciplinary consultancy, we combine technical expertise, creativity, and integrated delivery to lead complex, mission-critical projects.

Built on strong relationships, clear leadership, and a can-do mindset, Ethos is entering an exciting phase of growth, expanding our capabilities and taking on increasingly high-impact projects across EMEA and beyond.

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

We are seeking a motivated Project Design Engineer - Mechanical with 2–5 years of experience in mechanical design engineering within building services to join our Engineering Studio — a collaborative pool of engineers supporting multiple projects across the business. The Engineering Studio sits at the heart of our technical delivery, providing expertise across data centres, industrial, energy, pharmaceutical, and commercial sectors.

As a Project Design Engineer, you will play a key role in the delivery of high-quality mechanical design solutions across building services projects including commercial, healthcare, and mission-critical environments. Operating under limited supervision, you will take ownership of defined project tasks and lead smaller projects from concept through to completion.

Responsibilities:

Oversee specific elements of design work and coordinate with other disciplines; may supervise junior staff on assigned tasks.
Champion quality assurance (QA) across projects, performing audits and promoting compliance with internal QA systems.
Manage and maintain the project mechanical design file and contribute to the evolution of mechanical design standards.
Take technical ownership of mechanical systems throughout the full project lifecycle — from concept design to commissioning and handover.
Ensure continuous quality control of design and installation, aligning with CIBSE, ASHRAE, BS, IS, and EN standards.
Develop detailed mechanical specifications, tender packages, and reports, including value engineering analysis and client recommendations.
Liaise proactively with clients, contractors, and suppliers to resolve technical challenges during project delivery.
Support and mentor junior engineers, contributing to their professional development and team growth.
Promote a positive and proactive message internally and externally through consistent communication and behaviour.

About You

Technical Skills

Proficient in mechanical building services design, including HVAC, water systems, and fire protection.
Competent in design documentation and coordination using tools such as:

Microsoft Office Suite
AutoCAD and Revit MEP
Bluebeam for drawing review and mark-up
Familiarity with mechanical analysis software (e.g. Hevacomp, IES, or similar) is an advantage.

In-depth knowledge of applicable standards: CIBSE, ASHRAE, BS, IS, and EN.
Strong understanding of lifecycle design documentation, QA systems, and project file management.

Experience & Qualifications

The candidate must be based in Ireland to be considered for this position.
Typically 2–5 years of experience in mechanical design engineering within building services consultancy.
Degree in Mechanical Engineering or Building Services Engineering (or equivalent).
Working towards Chartered Engineer status (CEng) with Engineers Ireland or equivalent.
Experience managing or mentoring junior engineers is desirable.
Demonstrated ability to manage competing deadlines and multiple tasks efficiently.

Soft Skills

Strong interpersonal and communication skills; able to engage confidently with clients, contractors, and internal teams.
Excellent organisational skills with a proactive and structured approach to task management.
Adaptable and able to switch seamlessly between tasks and responsibilities.
Analytical thinker with problem-solving skills and the ability to make sound technical judgments.
Team-oriented, collaborative mindset with a drive to support both technical excellence and team culture.

Why Join Us?

Join collaborative leaders – Work alongside experienced, approachable professionals who
combine technical excellence with calm, supportive leadership.
Make a real impact – Contribute to mission-critical infrastructure projects that support the digital and energy transition across EMEA and beyond.
Grow with us – As a rapidly growing consultancy, we offer opportunities to develop your skills, broaden your experience, and build your career.
Shape a more sustainable future – Sustainability isn't an initiative—it's embedded in every project, every discipline, and every decision we make.

We offer:

Flexible Fridays and a 9-day fortnight working schedule — enjoy every second Friday off to maintain work–life balance.
A culture that values flexibility, learning, and teamwork, with clear progression pathways and support toward professional accreditation.
Opportunities to work alongside some of the most experienced engineers in the industry, within a forward-thinking, technology-driven consultancy.

Benefits:

Flexible working times
20 Days holidays up to 25 days
Pension Scheme
Refer a Friend scheme
Healthcare check-ups and flu vaccinations
Gym / Fitness membership Allowance
Subsidised Health Insurance Allowance
Working travel out-of-pocket expenses
