The Role

The Key Account Manager leads the strategic, commercial, and operational success of major telco customers. The role exists to drive profitable growth, strengthen long‐term customer partnerships, and ensure outstanding delivery performance. It is accountable for full customer lifecycle ownership, from strategy and commercial planning to execution and satisfaction outcomes.

Key Roles & Responsibilities

You will act as the senior point of contact for one or more large, strategic customers, building strong relationships with C-level and senior stakeholders. You’ll lead the creation and execution of multi-year account strategies, oversee commercial negotiations, and manage full P&L performance.

Working across Sales, Commercial, Finance, Delivery, Operations, Technology and Legal, you’ll coordinate cross-functional teams to ensure integrated solutions, strong governance, and service excellence.

This is a highly visible role, interacting regularly with executive customer stakeholders, internal senior leadership, and operational delivery teams — while also contributing insight and leadership into the wider commercial strategy.

Delivery & Performance

You will be accountable for delivering sustained, profitable growth across your account portfolio, including:

• Revenue growth and margin optimisation
• Cost control and accurate financial forecasting
• Contractual performance and governance across the full lifecycle
• High customer satisfaction and delivery reliability

You’ll independently lead complex, high-value negotiations including contract formation, renewals, variations, remediation and change control. You will identify and realise upsell, cross-sell and solution expansion opportunities, converting customer demand into long-term commercial value.

You will also lead the resolution of complex commercial and operational escalations, applying sound judgement to protect customer relationships, delivery outcomes, and commercial position.

Success will be measured through revenue and margin performance, forecast accuracy, contractual compliance, delivery reliability, customer satisfaction, and the depth and resilience of senior customer relationships.
