Executive Assistant

Executive Assistant to the Managing Director

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.

Established in 2018, Mantis Energy has grown into a multi-service Net Zero engineering, energy consultancy and construction business — spanning low energy building design, energy & sustainability consulting, M&E contracting, building services engineering, project & contract management, on-site construction, energy procurement and facilities management, delivered across the education, healthcare, commercial, residential, social housing and renewable energy sectors.

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.

• Electrical Vehicle Salary Sacrifice Scheme
• Cycle to Work Scheme
• Sustainable Volunteering Day

THE ROLE (but not limited to):

• Rescheduling meetings where appropriate and proactively reminding the MD of important commitments so nothing is missed
• Building recurring strategic planning time into the diary as a fixed, protected commitment that consistently goes ahead

Inbox, Meetings & Reporting

• Triaging and organising the MD’s inbox daily, filtering out noise, drafting and sending short routine responses within agreed parameters, and managing follow-ups so nothing important is missed
• Acting as a courteous first point of contact for the MD by phone and email, and holding regular check-ins to agree what you can action directly and what needs his input
• Attending key meetings with the MD to take clear, accurate minutes, circulating these promptly with action points, and chasing owners who are behind through to completion
• Preparing meeting agendas and briefing notes in advance, and coordinating a consistent, recurring cadence of manager reporting meetings and KPI reviews so they never slip
• Scheduling and protecting the monthly cash flow and invoicing meeting with Finance, and keeping reporting templates, trackers and KPIs organised and up to date

Instructing, Chasing, Travel & Purchasing

• Turning the MD’s direction into clear written instructions for staff, contractors and suppliers, and chasing outstanding information, documents and decisions until resolved
• Negotiating routine matters (pricing, scheduling, terms) on the MD’s behalf…
