Senior/Principal Electrical Engineer Cambridge Up to 65k Overview Three and a half years ago, one of Cambridge's newer building services teams was just getting going. It's grown steadily since, built on a simple idea: take the best bits of the big consultancies and the best bits of the small ones, and leave the rigid banding and reduced autonomy behind.

The Role You'll join a growing Cambridge-based consultancy as an Electrical Engineer, reporting into an Associate who leads the discipline. The level is genuinely open, so whether you're operating at senior or principal capability, there's a route that fits. Get involved earlier in the design process. The team has historically leaned heavily on Stage 3/4 onwards work and is actively rebalancing towards more early-stage involvement Senior engineers are expected to lead their own...
