Executive Assistant in Wilmslow

At Mantis we are looking for someone who prides themselves on accuracy, is highly organised, trustworthy and proactive, ready to become the right hand to our Managing Director and play a key role in helping the business run smoothly at the top. This is a fast-paced role that requires juggling competing priorities and managing your time efficiently – we are looking for a high performer who works best under pressure and enjoys variety across their workload.

As our Executive Assistant to the Managing Director, you will take ownership of the diary, inbox, travel and purchasing that currently eat into the MD’s time, acting as a trusted filter and gatekeeper so that time is protected for the highest-impact work. You will become an integral part of a friendly and dynamic business based in the heart of Wilmslow town centre, working closely with the MD and senior leadership team.

This is a role built on trust, discretion and initiative. You will make sound judgement calls on the MD’s behalf, know what genuinely needs their attention versus what can be delegated, and represent them professionally in written and verbal communication.

Our MD leads in a direct, plain-spoken and outcomes-focused way, so this role suits someone with genuine resilience who takes feedback professionally, holds their ground, and is confident chasing people for answers.
