Senior Account Manager

Remote / Hybrid

• Permanent
• Client Services
  
  

Sonin is a technology product consultancy, helping ambitious businesses design, build and scale digital products that matter. As we grow our client services function, we're looking for a Senior Account Manager to own a portfolio of key relationships — someone who can balance commercial rigour with genuine partnership, and who's just as comfortable in a boardroom as they are in a sprint planning session.

This is a pivotal role as Sonin evolves from project-based app delivery towards a product consultancy model. You'll be central to how we deepen client relationships, spot new opportunities, and ensure the work we deliver keeps earning trust.

What You'll Do

• Lead client relationships end to end. Own and grow a portfolio of key client accounts, acting as the primary point of contact for strategic and commercial decisions.
• Identify new business within your accounts. Spot upsell and cross-sell opportunities within existing accounts, and shape proposals that reflect real client needs.
• Partner with delivery teams. Work closely with development, design and product teams to keep projects on track, on budget, and to a high standard.
• Manage multi-level stakeholder relationships. Build relationships from day-to-day contacts through to senior stakeholders and C-suite sponsors.
• Own commercial negotiations. Lead conversations on scope, pricing, renewals and contract terms, protecting margin while keeping clients happy.
• Monitor account performance. Track account health and revenue forecasts, flagging risk early and building plans to address it.
• Represent Sonin externally. Attend client meetings, workshops and industry events as a face of Sonin.
• Coach junior team members. Support and mentor account coordinators as the team grows.
  
  

What We're Looking For

Essential

• Proven experience as an Account Manager or Senior Account Manager within a digital agency, software consultancy, or similar client-facing technology environment.
• A track record of growing client accounts and meeting or exceeding revenue targets.
• Strong commercial acumen, with confidence discussing scope, pricing and contracts.
• Excellent stakeholder management skills, able to flex your style across technical and non-technical audiences.
• Comfortable working alongside developers, designers and product managers, translating between technical detail and client priorities.
• Highly organised, with the ability to manage multiple accounts and competing priorities without dropping the ball.
  
  

Nice to Have

• Experience within a company transitioning from project-based delivery to a product consultancy model.
• Familiarity with agile delivery methodologies (Scrum, Kanban).
• Experience using CRM tools to manage pipeline and account data.
  
  

What We Value

• Honesty first — we do what's right for the client and the business, even when it's the harder conversation.
• Collaboration over silos — great outcomes come from developers, designers and account teams genuinely working as one.
• Craft and quality — we take pride in the detail, because clients notice it too.
• Ownership — we're growing and changing, and we back people who bring ideas rather than wait to be told.
