Account Manager (Post-Sales & Account Development - Retail & CPG)

Arkham is a Data & AI Platform that helps large enterprises turn fragmented operations into trusted data and AI that moves the business: we unify fragmented systems, build a single source of trusted operational metrics, and solve complex challenges with AI tailored to each operation (sell-out forecasting, pricing and promo analysis, replenishment, automated order assignment). Teams at Circle K and Kimberly-Clark partner with Arkham to deploy AI-powered solutions.

As an Account Manager, you make sure the customer gets the outcome they bought, and you turn that outcome into renewal and expansion. You are a customer-facing consultant: you understand the customer’s operation, commercial side and P&L, translate what the platform does into measurable impact, and grow the account into new areas, business units, countries and use cases. While the Growth team closes the deal, you own everything that comes after it: the relationship, the results, and the retained and expanded ARR. You report to the Head of Account and work with Forward Deployed Engineers, Growth Managers and Sales Engineers.

What you’ll do:

• Take the deal handoff and build the account success plan: business objectives, impact metrics, milestones and owners on both sides.
• Run the relationship: weekly operational cadence with users, monthly with leadership, and QBRs with the executive sponsor.
• Drive adoption and outcomes: make the platform part of daily operations (replenishment, forecasting, control tower), and measure and report impact in P&L terms.
• Spot and resolve risks early (data, adoption, sponsor changes, competition, budget) and escalate on time.
• Point the technical team (FDE) at what the customer needs, without promising what can’t be delivered.
• Grow the account: find whitespace, build the expansion business case and take it to close with the Growth Manager.
• Lead renewals: prepare the evidence of value, negotiate terms and secure continuity.
• Manage platform consumption (ATUs), billing and contract compliance.
• Document success stories and references the Growth team can use to sell.

How we measure success: Net Revenue Retention · platform adoption per account · business impact validated by the customer · account health score, with risks caught early · success stories and references generated.

Requirements

• 5–8 years managing and growing enterprise accounts in Account Management, Customer Success, Key Account Management, implementation consulting or Client Partner roles.
• Retail or CPG experience, either at the company or serving it, with a solid grasp of commercial, operations and supply chain.
• Sales sense: you spot opportunities, build a business case and bring an expansion or renewal to signature.
• A consultant’s approach: you structure problems, prioritize, and communicate clearly with both operations and leadership.
• Comfortable with data and technology: you read dashboards, understand a forecasting model at a conceptual level and can hold a basic technical conversation. No coding required.
• Strong project and stakeholder management: you deliver what you promise and keep everyone aligned.
• Professional English.
• Based in Mexico City or Monterrey, with availability to travel to customers.
• Nice to have: experience with SaaS or data platforms; experience managing technology implementations in Retail or CPG.

This role is not for: a project manager who reports progress without understanding the business, a reactive customer success rep who waits for tickets, or a seller who wants to close and move on.

Benefits

• Own relationships with some of the largest Retail and CPG enterprises in LATAM.
• Direct impact on retention and expansion at a fast-scaling Data & AI company.
• Hybrid work model.
• Competitive compensation with a variable component tied to results.
