Overview

We are looking for a highly capable, proactive and strategically minded Senior Account Manager to support one of our flagship accounts across CRM, paid media, event activation, sales enablement and reporting. This is a diverse and fast‑paced role suited to someone who enjoys variety, is confident managing complex multi‑channel workstreams, and thrives in a collaborative, integrated team environment.

While CRM remains a core part of the role — especially managing customer journeys built through Salesforce Account Engagement in partnership with our Tech and Data teams — you will also play a key role supporting clients across paid media delivery, event support, content and creative production, and performance measurement.

You will work closely with project management, creative, media, strategy, data and UX teams to ensure smooth and efficient delivery across all channels.

Key Responsibilities

CRM Campaign & Journey Management

• Coordinate timelines, content requirements, logistics, attendance lists, and post‑event communications.
• Support onsite materials, briefing documents and follow‑up activity across CRM, social, and sales enablement.

Sales Enablement & Content Delivery

• Support the development of sales enablement materials such as decks, one‑pagers, playbooks, product sheets and internal toolkits.
• Work closely with creative, design and content teams to ensure high‑quality, on‑brand outputs.
• Ensure materials are aligned to client go‑to‑market strategies and activation plans.

Measurement, Insight & Reporting

• Support the creation of performance reports across CRM, paid media, event activity and content.
• Work with Data & Analytics to review KPIs, identify trends and surface opportunities for improvement.
• Present reporting back to clients confidently with clear narratives and actionable recommendations.

Client Relationship Management

• Build trusted day‑to‑day relationships with client stakeholders.
• Present creative work, take in feedback and provide clear updates throughout each stage of delivery.
• Work with senior team members to ensure all work aligns to wider CRM strategy, customer goals and KPIs.
• Manage expectations around timelines, dependencies and partner workflows.

Customer Understanding & Insight

• Demonstrate a strong understanding of the client’s customer base, CRM performance, lifecycle stages and loyalty motivators.
• Share insights, trends and optimisation opportunities with both clients and internal teams.
• Use data and performance learnings to help shape future briefs and creative direction.

Cross‑Functional Collaboration

• Partner closely with Project Management to ensure smooth operational delivery across all channels.
• Work with Creative, Media, Strategy, Data, CX and Tech teams to coordinate seamless end‑to‑end execution.

The Six Helia Habits

Get Involved

You take ownership of outcomes rather than sticking narrowly to your role. You willingly step in, collaborate and help drive projects forward — ensuring the work succeeds, not just your part of it.

Have a Voice

You speak up, contribute ideas and challenge constructively. You bring energy and opinion to conversations, and you see being active and vocal as the default, not the exception.

Find a Way

You don’t get stuck on limitations — whether they’re client constraints, brief challenges or process barriers. You think creatively, problem‑solve with optimism and look for practical ways to move things forward.

Be Playful

You bring curiosity, experimentation and positivity to the work. You’re not afraid to explore, try new approaches or inject creative thinking into everyday tasks — even when deadlines are tight.

It Only Counts If You Make It

You turn thinking into action. You help transform good ideas into real, tangible outcomes — moving beyond theory to delivery and results.

Make It Better Than It Was

You’re always looking to elevate the work. You don’t settle for “good enough”; you ask, “Is this the best it can be?” and push for quality, craft and continual improvement.

Equal Opportunity Statement

Here at Havas helia across the group we pride ourselves on being committed to offering equal opportunities to all potential employees and have zero tolerance for discrimination. We are an equal opportunity employer and welcome applicants irrespective of age, sex, race, ethnicity, disability and other factors that have no bearing on an individual’s ability to perform their job.
