Who Are We Looking to Add to Our Team?

As an Account Manager at Massive Rocket, you’ll own and grow strategic relationships across a portfolio of clients — acting as a trusted partner responsible for driving measurable ROI, deepening engagement, and ensuring long-term success.

This is not a new business sales role. Instead, you’ll focus on retention, expansion, and value realisation within existing partnerships. You’ll develop a deep understanding of your clients’ business models, priorities, and challenges, and connect these to the value Massive Rocket delivers across CRM, data, and Martech.

Sitting at the intersection of client success, delivery excellence, and commercial ownership, you’ll ensure every programme is aligned to client outcomes, while identifying opportunities to expand scope, introduce new capabilities, and strengthen long-term partnerships.

What Will You Do?

• Build and maintain strong, multi-threaded relationships across your client portfolio, acting as the primary point of contact for strategic and commercial discussions.

• Develop a deep understanding of client business goals, operating models, and success metrics

• Lead strategic account reviews, EBRs, and planning sessions, clearly linking Massive Rocket’s work to business outcomes and ROI

• Act as the voice of the client internally, ensuring delivery teams are aligned to client priorities and expectations

• Proactively manage escalations, risks, and performance issues, ensuring consistent delivery excellence

• Identify and unlock growth opportunities within existing accounts, including new teams, departments, and use cases

• Drive account expansion through upsells, renewals, and scope evolution in collaboration with internal teams

• Own forecasting, pipeline visibility, and commercial performance across your portfolio

• Collaborate closely with Programme Management and Delivery teams to ensure alignment, resourcing, and profitability

• Contribute to continuous improvement by sharing best practices, insights, and client learnings across the business

What Makes You a Great Fit

• Proven experience managing and growing client portfolios within an agency, SaaS, or consulting environment

• Strong relationship management skills, with experience engaging stakeholders across VP, Director, and operational levels

• Track record of driving retention, expansion, and long-term client value

• Strong commercial acumen, including forecasting, revenue ownership, and profitability management

• Ability to connect business strategy with practical CRM, data, or Martech solutions

• Excellent communication and stakeholder management skills, including handling escalations effectively

• Proactive, consultative mindset focused on delivering measurable value to clients

• Experience working cross-functionally with delivery, strategy, and technical teams

• Comfortable operating in fast-paced, client-driven environments

• English proficiency at C1 level
