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.
