About the Role

This role description outlines the core responsibilities of a Senior Account Director (SAD) at Greenpark. However, a job description should not be viewed as a fixed set of boundaries. In a business like ours, we encourage proactive thinking, collaboration, and contribution beyond defined responsibilities.

The Senior Account Director is a key role within Client Services. As a SAD, you are seen by clients as the lead across your accounts – responsible for ensuring the smooth, strategic delivery of multiple projects while deepening client partnerships and driving growth.

You work closely with both client and internal teams to keep delivery teams on track, proactively solving issues and keeping momentum high. You build strong, senior-level relationships across the client’s organisation (including their partners and agencies), positioning yourself as a trusted partner who understands not just their needs, but their broader business priorities. You are comfortable challenging client feedback when necessary on SOWs, strategy, creative, ways of working and most importantly able to offer solutions that benefit the client and the agency with ease.

You should have full visibility of the client’s annual budget and be confident navigating commercial conversations, challenging out of scope requests, spotting opportunities for growth, upselling strategically and shaping the partnership for the long term.

Your role is to lead with perspective: understand the client’s world, guide your teams to deliver effectively, and ensure every interaction adds value to the relationship.

Responsibilities

Client Relationships

Develop a deep understanding of each client’s business, their industry, key competitors, commercial pressures, objectives and challenges, in order to proactively identify opportunities and solutions

Understand your client on a personal level, becoming their trusted advisor – knowing how they like to communicate, their career aspirations and frustrations, and how Greenpark can support them

Lead difficult or sensitive conversations with clarity, empathy and professionalism – including navigating challenging feedback, resetting expectations, challenging client direction (SOW, creative, WoW) and resolving misalignment, while maintaining strong long-term relationships

Maintain regular contact with clients beyond formal meetings, taking a genuine interest in them as individuals and in the success of their business

Alongside your CS Lead, drive account plans and QBRs, presenting them with clarity and conviction, owning the agency’s recommendations in front of clients and influencing conversations at a senior level

Ensure every brief, recommendation and output is connected to a clear strategic purpose (and push back on the client if we don’t agree) – not just ensuring quality but raising the bar on what great looks like and holding the team to that standard

Bring a strong, informed point of view grounded in a deep understanding of the client’s category, customer and competitive landscape; use this knowledge to challenge assumptions, bring fresh thinking and strengthen Greenpark’s strategic offering

Proactively identify growth opportunities – in real time and off the back of key meetings such as QBRs, monthly reporting or briefings – guiding the team and clients beyond the day-to-day

Coach junior CS team members to stretch their own strategic thinking, helping them ask better questions and draw meaningful insights from performance

Set the tone for a proactive, insight-led culture on your accounts – always pushing the work, the team and the client’s thinking forward

Forecasting & KPIs

Confidently translate high-level client objectives into clear, measurable KPIs, engaging the right internal specialists where needed and ensuring these are cascaded across your team so everyone understands what we’re driving towards and, most importantly, why it matters

Play a critical role in forecasting and business planning, working closely with Snr BD and HoCS to develop robust, insight-led projections

Proactively monitor performance, identifying early signals that may require intervention and flagging risks before they become issues

Move beyond surface-level data to uncover the drivers behind results, explore hypotheses and identify opportunities to influence performance effectively

When challenges arise, rally the right people to craft a considered response and communicate this clearly and confidently to clients

Commercial Growth

Support the Client Lead to deliver against revenue targets for assigned accounts through client retention, organic growth, strategic upsell and expansion opportunities

Maintain full visibility of the client’s annual budget and be confident leading commercial conversations at a senior level
