Senior Sales Associate in London

We are strengthening support for our largest and most complex global customers by introducing a Senior Sales Associate role. This role focuses on providing deep commercial, operational, and stakeholder support to a small number of top-tier, high-value accounts, partnering closely with Account Executives (AEs) to deliver consistent revenue growth, strong customer outcomes, and a best-in-class customer experience.

The Senior Sales Associate manages increased complexity, scale, and senior-level engagement while remaining an individual contributor role, with no people management or hierarchical responsibility over Sales Associates.

The Senior Sales Associate focuses on:

• Supporting the AE in managing large, complex, and global customers
• Owning and driving high-value and complex commercial activities
• Engaging with senior customer stakeholders and internal leadership
• Ensuring rigorous execution across renewals, rerates, and transactional activity for strategic accounts

This role is well-suited for a commercially experienced sales professional who thrives in complex customer environments and enjoys operating as a trusted partner to both customers and AEs.

What you will do

Strategic Customer Engagement & Governance

• Partner closely with the AE to manage a small portfolio of Colt's most strategic and complex accounts.
• Act as a senior day-to-day commercial contact, building strong relationships with senior customer stakeholders and key internal teams.
• Lead and contribute to customer governance activities such as service reviews, operational forums, and commercial touchpoints, while supporting AE-led strategic engagements (QBRs, account planning, executive sessions).
• Drive structured stakeholder engagement planning, ensuring alignment and effective communication across Colt and customer organisations.
• Anticipate customer risks, dependencies, and commercial opportunities within complex, multi-national account environments.

Advanced Commercial Management & Opportunity Execution

• Own and manage complex transactional and renewal-related sales activities end to end, including pricing, rerates, contract changes, and commercial negotiations.
• Drive opportunity progression across multiple products, regions, and stakeholders in partnership with Sales Engineering, CRM, Product, Deal Pricing, Legal, and Finance.
• Support the AE in identifying, shaping, and executing large or complex expansions, cross-sell, and upsell opportunities.
• Proactively manage high-value renewals to secure retention, improve outcomes, and identify growth opportunities.
• Ensure commercial activity aligns with customer strategy, contractual obligations, and internal governance.
• Participate in customer meetings to progress opportunities, resolve issues, and strengthen commercial relationships.
• Support customer satisfaction initiatives and act as a point of escalation for complex commercial queries where appropriate.

Data, Process & Sales Excellence

• Ensure Salesforce data for assigned customers is accurate, complete, and continuously updated to enable reliable reporting, forecasting, customer communication, and pipeline visibility.
• Apply a disciplined approach to opportunity tracking, renewal planning, and commercial execution.
• Share best practices and insights across the team, supporting continuous improvement in how complex accounts are managed.
