As Lead CS, you'll be both a builder and hands-on operator. You'll own key client relationships directly, while shaping the processes and playbooks that will let our CSM function scale. You'll be the first hire in this function - the de-facto authority on CSM strategy from day one, setting the standard others follow as the team grows. This is a high-ownership role for someone who wants to grow into a Head of CSM position as the team expands, with real influence over how CSM is structured from the ground up.

• Own a portfolio of key client relationships, driving retention, expansion, and satisfaction.
• Prioritize and manage the ongoing stream of customer requests, ensuring fast, clear, and effective resolution.
• Make key decisions on client prioritization, escalation handling, and resource allocation without needing sign-off on every call.
• Build and document CSM processes, playbooks, and best practices — the foundation the function scales on.
• Be directly involved in shaping how the CSM function is structured, staffed, and measured as it grows, including hiring the next CSM(s).
• Represent the CSM function in leadership/strategy discussions, bringing client insight directly into product and business decisions.
• Partner with Sales, Product, Data, and Engineering to ensure clients achieve their business goals through our platform.
• Define and track key CSM KPIs and report progress to leadership.
• Collect and synthesize client feedback to influence the product roadmap and prioritize features that improve value delivery.

• 3-5+ years of experience in Customer Success, Account Management, or related functions.
• Track record of being the go-to expert or point person on your team, even without formal reports — people come to you for judgment calls.
• Experience managing enterprise or high-growth startup clients with complex needs.
• Comfortable representing the function at leadership level and pushing back on priorities when needed.
• Strong analytical background; comfortable working with BI tools to generate client insights.
• Excellent communication skills, with the ability to influence senior stakeholders.
• A proactive, ownership-driven mindset — comfortable operating with ambiguity in a fast-paced startup.
• English proficiency: C1.

• Experience or interest in building/scaling a CSM function, defining org structures, processes, and KPIs.
• Deep understanding of performance marketing KPIs (LTV, ROAS, CAC, retention) and B2C growth strategies.
• Experience in analytics-focused or performance marketing companies.
• Familiarity with predictive analytics or attribution modeling.

• Competitive salary + performance bonus.
• Fully remote with flexible working hours.
• Home office stipend and learning & development budget.
• 21 paid vacation days.
