Mechanical Engineer

Mechanical Engineer

Don't join an Engineering firm. Build what comes next.

Most roles ask you to deliver drawings. This one expects you to shape systems that change how buildings perform and how people live.

The Role

You'll work across the full project lifecycle, designing mechanical systems and influencing decisions from day one. You won't just deliver designs, you'll help shape how projects perform, working closely with teams, clients, and stakeholders.

What You'll Do

• Design mechanical building services systems across multiple sectors
• Deliver projects from concept through to construction and handover
• Produce calculations, specifications, and technical reports
• Coordinate with electrical engineers, architects, and design teams
• Attend client meetings and contribute to engineering decisions
• Support site inspections, commissioning, and final delivery
• Drive energy-efficient and sustainable design solutions

What You'll Bring

• Degree in Mechanical or Building Services Engineering
• 2 to 5+ years' experience in a consultancy or similar environment
• Strong HVAC and building services design experience
• Experience with IES, Hevacomp, or similar; Revit beneficial
• Ability to manage workload across multiple projects
• Strong communication and client-facing skills

What You'll Get

This isn't built around perks. It's built around how high-performing engineers actually want to work. Real ownership, real progression, and a culture that trusts you to deliver.

The Essentials

• Competitive salary, bonus and pension that reflect your impact
• 22 to 27 days annual leave, plus bank holidays
• Flexible working across a 37.5 hour week (x5, 7.5 days): early start or later start? You decide

Career Progression

• A clear path forward, with responsibility increasing as you prove it
• Direct exposure to senior leaders, not layers of hierarchy
• IN2 Academy, CPD support and chartership guidance
• Fully paid professional fees

Health and Wellbeing

• Employee Assistance Programme and annual health checks
• Wellbeing and fitness initiatives that support you long term
• Cycle to Work scheme to make the everyday easier

Social and Community

• Genuinely strong team culture, built through regular events and shared wins
• Employee-led charity initiatives with real involvement
• Offices in Dublin, London, Berlin, Belfast, Athlone and Madrid

Why IN2?

Across every role, electrical, mechanical, or BIM, the IN2 difference is the same: you're expected to think, lead, and shape outcomes, not just execute instructions. Here's what sets us apart.

Ownership from Day One

Whether you're an Engineer or a Senior, you'll have real accountability and decision-making authority. No waiting for permission. No layers of sign-off slowing you down.

Progression Based on Ability

Faster progression based on what you deliver, not how long you've been in the seat. A clear pathway from Engineer to Senior, Associate, and beyond.

Innovation Time

Dedicated time to develop new ideas, explore emerging technologies, and contribute to sustainability strategies: built into how we work, not bolted on.

High-Performance, Low-Ego Culture

A team that challenges each other, supports each other, and wins together. No hierarchy for hierarchy's sake. Just talented people doing exceptional work.

Complex, High-Profile Projects

Exposure to design-led, high-impact developments that push the boundaries of what building services engineering can achieve.

Global Reach

Work across offices in Dublin, London, Berlin, Belfast, Athlone, and Madrid- a genuinely international practice with a collaborative, connected culture.
