Executive Assistant to Chief Executive Officer

Executive Assistant to Chief Executive Officer

ENSEK, Nottingham, England, United Kingdom

We are a technology business operating in the global energy sector. ENSEK has become the go‑to option for top energy suppliers worldwide, offering a significant step‑change away from legacy systems and a cheaper solution without compromising service or standards. Our people are our superpower.

As Executive Assistant, you will be the trusted right hand to Jon Slade, ENSEK’s CEO, enabling focus on strategic priorities through flawless planning, communication, and follow‑through. You will manage the CEO’s operating rhythm – calendar, meetings, information flow, and stakeholder engagement – and partner closely with the Chief of Staff to drive leadership cadence, board preparation, and executive accountability.

• Own end‑to‑end calendar strategy for the CEO: prioritisation, gatekeeping, and proactive scenario planning to maximise time on company priorities.
• Prepare the CEO for all interactions (ELT, Board, key customers, investors): briefings, agendas, pre‑reads, talking points, and clear decision logs.
• Coordinate travel and logistics for CEO and broader ELT; manage expenses and approvals with discretion and accuracy.
• Coordinate ELT, Leadership Board and Executive Board cycles (agendas, materials, distribution, minutes, actions), working closely with the Chief of Staff; ensure inputs are timely, consistent and high quality.
• Act as a high‑credibility interface to senior internal and external stakeholders (Directors, EAs, customers, partners, investors), ensuring professional, timely responses and immaculate document handling.
• Draft and refine executive communications (emails, memos, updates) in the CEO’s voice; maintain confidentiality at all times.
• Maintain a well‑structured “Executive Office” hub for documents, meeting artefacts, and workflows; implement simple SLAs for responses and approvals.

• Increased CEO time spent on strategic agenda versus reactive or administrative tasks.
• Leadership rhythm health: ELT/Board materials delivered “first‑time right,” on schedule; actions closed within agreed SLAs.
• Stakeholder satisfaction:
  Positive feedback from ELT, Board directors and key external counterparts; prompt, accurate correspondence.

• Significant experience as EA to a CEO or C‑suite leader in a high‑growth, complex environment (scale‑up, SaaS or energy sector advantageous).
• Demonstrated experience preparing Board and Exec‑level materials, running executive meeting cycles, and coordinating across multiple senior stakeholders.
• Advanced proficiency across Microsoft 365 (Outlook, Teams, One Drive/SharePoint, PowerPoint, Excel); exceptional written and verbal communication.
• Judgement & discretion:
  Handles sensitive information with absolute confidentiality.
• Organisation & anticipation:
  Plans ahead, identifies risks, solves problems before they surface.
• Influence & relationship management:
  Builds trust across the ELT and with external partners; represents the CEO with polish and credibility.
• Execution & follow‑through:
  Drives actions to closure; establishes simple, visible metrics for responsiveness and quality.
