Full‑time

Customer Success isn’t a support function – it’s frontline cyber defence. In this role you’ll act as the primary partner for customers, driving renewals, growth opportunities and end‑to‑end service delivery.

• Support the Head of Customer Success in running a world‑class customer success function.
• Take accountability for renewals, re‑contracting and solution evolution to minimise churn and maximise customer lifetime value.
• Maintain a clear, accurate forecast of your pipeline – renewals, expansions and opportunities in flight.
• Meet customers regularly to understand their challenges and map them to the right CyberOne services and technology.

• Build deep, trusted relationships with customers at every level – from IT teams to senior stakeholders.
• Become the go‑to person for everything service‑delivery related.
• Lead structured monthly/quarterly service reviews, ensuring actions are agreed, owned, and delivered on time.
• Support account development planning with commercial awareness and sharp customer insight.

• Manage delivery against contracted SLAs and service schedules, ensuring we meet obligations and exceed expectations.
• Direct and oversee order processing, fulfilment and customer requests end‑to‑end.
• Handle escalations calmly and professionally, including producing Root Cause Analysis reports that strengthen customer confidence.
• Keep internal teams aligned and informed so we move as one team around the customer.

• Produce monthly, quarterly and annual service reports and deliver them via our customer portal.
• Identify where processes can be improved for speed, quality and effectiveness – then help implement those changes.
• Assist with internal statistics and reporting to support decision‑making across the business.
• Support resourcing for projects and pre‑sales work.
• Own and maintain the Monday.com system and collaborate across other operating platforms as needed.
• Generate Statements of Work, managed service schedules, welcome packs and coordinate contract delivery with Operations.

• Customers renew confidently and view CyberOne as vital to their cyber resilience.
• Pipeline is visible, dependable and growing – with new value being created, not just maintained.
• Service reviews are proactive, structured and lead to action.
• Escalations are rare – and when they happen, they’re handled quickly, transparently and professionally.
• Internal teams feel supported and aligned around a clear customer plan.

You’re organised, accountable and customer‑obsessed with commercial instincts to spot growth opportunities and operational sharpness to keep delivery on track.

• Excellent administration, organisation and time‑management skills.
• Strong analytical ability with a practical, problem‑solving mindset.
• High attention to detail – you don’t let things slip.
• Confident written and verbal communication skills, including customer‑facing reporting.
• A proactive, self‑starting style – comfortable working independently or as part of a team.
• The ability to learn quickly and become fluent in the security services and tech we deliver.
• Working knowledge of CyberOne systems (or the capability and drive to pick them up fast).
• Strong skills across Microsoft tools (PowerPoint, Power BI, Word, Excel).
• Customer‑facing and administrative experience in a cyber/IT services environment.
• Broad understanding of cyber security and managed service delivery.

CyberOne is an elite cyber defence team – CREST SOC certified, NCSC‑assured incident responders and Microsoft‑first across everything we do.
