OVERVIEW:

We’re looking for a Customer Strategy Manager to own relationships with a portfolio of mid-market clients and help them grow their businesses through data-informed strategy.

In this role, you will connect clients’ business goals with advertising performance, investigate challenges, and turn complex information into clear recommendations. You will work closely with channel strategists and internal teams to guide priorities, address underperformance, and identify growth opportunities.

We’re looking for someone who combines analytical thinking with strong client judgment: someone who asks thoughtful questions, takes ownership of problems, and can confidently guide difficult conversations. You should be comfortable challenging assumptions, explaining trade-offs, and helping clients make informed decisions—even when your recommendation differs from their initial expectations.

Prior experience in advertising or e-commerce is helpful, but not required. We welcome candidates from other industries who bring strong analytical skills, client advisory experience, and a track record of solving business problems. You will develop expertise in Quartile’s platform and the advertising channels that support our clients.

REQUIREMENTS:

• 3+ years of professional experience in a client-facing role involving advisory work, relationship management, or responsibility for business outcomes.

• Demonstrated ability to use data to diagnose problems, identify performance drivers, evaluate options, and recommend practical next steps.

• Proficiency in Microsoft Excel, including formulas, lookup functions, pivot tables, and organizing and analyzing datasets.

• Strong communication skills, with the ability to explain complex information clearly and support recommendations with evidence.

• Experience navigating difficult client conversations, managing disagreement, and constructively challenging assumptions while maintaining trust.

• Sound judgment and resilience when handling competing priorities, changing circumstances, and problems that do not have an obvious answer.

• A strong sense of ownership, including following through on commitments and coordinating with others to resolve issues.

• Curiosity and willingness to learn new tools, business models, and advertising concepts.

• Fluent spoken and written English, with the ability to lead client meetings and communicate complex recommendations confidently.

NICE TO HAVE:

• Experience advising clients on decisions that affect revenue, profitability, investment, or operational performance.

• Experience in consulting, financial services, commercial account management, operations, or other roles combining analysis with client responsibility.

• Experience managing a portfolio of clients or coordinating multiple complex projects.

• Familiarity with e-commerce, retail, digital advertising, or advertising technology.

• Exposure to advertising or analytics platforms such as Amazon Ads, Google Ads, Meta Ads, Microsoft Advertising, or Google Analytics.

• Experience working in a fast-paced environment with substantial responsibility and changing priorities.

WHAT YOU’LL DO:

• Own relationships with a portfolio of 15+ key mid-market accounts, understanding each client’s business goals, priorities, and challenges.

• Monitor KPIs, investigate underperformance, and connect advertising results to the client’s broader business objectives.

• Develop clear, data-backed recommendations and work with channel strategists to prioritize and implement campaign optimizations.

• Lead regular weekly or biweekly client meetings, communicating performance, explaining recommendations, and aligning on next steps.

• Guide challenging conversations with confidence and professionalism, address concerns, and explain trade-offs when expectations or priorities differ.

• Prepare client reports and quarterly business reviews that connect results, opportunities, and recommended actions to business goals.

• Coordinate with internal teams to resolve issues, maintain accountability, and follow through on client commitments.

• Identify opportunities to expand Quartile’s partnerships through additional channels, budget allocation, and testing initiatives.

• Build expertise in Quartile’s platform, digital advertising, e-commerce, and retail through product training, roadmap sessions, and ongoing learning.

• Share recurring client needs and data-backed improvement opportunities with Product and Technology teams.

• Partner with the Implementation team during onboarding to understand client objectives and support a smooth transition into ongoing account management.
