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.
