Requirements

  • Proven experience leading engineering teams while remaining technically hands-on, with technical depth comparable to Staff level.
  • Experience shipping and operating an AI agent, copilot, or agentic system serving real users, including diagnosing and fixing production issues.
  • Experience managing, coaching, and growing engineers up to Senior level, handling performance conversations, and building a healthy team culture.
  • Hands-on experience with agent frameworks or orchestrators such as LangGraph, LangChain, or equivalent; large language model provider application programming interfaces such as Claude, OpenAI, or Gemini; vector databases; and evaluation frameworks.
  • A strong software engineering foundation, including the ability to review code and architecture and reason about agents as distributed systems with failure modes.
  • Judgment on agentic-system trade-offs involving latency versus quality, autonomy versus control, and cost versus accuracy.
  • Experience with planning, prioritization, delivery ownership, and stakeholder alignment without requiring a dedicated Technical Program Manager.
  • Ability to influence cross-functional decisions with Product, Design, and business stakeholders.
  • Experience working in agile, collaborative, multidisciplinary environments and communicating with technical and business audiences.

Responsibilities

  • Lead, coach, and grow a team of AI Engineers, including onboarding, performance check-ins, feedback, and career development within the company career framework.
  • Own delivery of the team’s AI agents roadmap by prioritizing with Product Managers, planning and sequencing work, and committing to realistic outcomes.
  • Set technical direction with Staff AI Engineers through architecture reviews, engineering standards, and build-versus-buy decisions concerning frameworks, model providers, retrieval, and orchestration.
  • Be accountable for production reliability, including on-call readiness, incident response, post-mortems, and root-cause fixes.
  • Set and uphold quality standards for agentic systems, including evaluations, guardrails, observability, and monitoring.
  • Review architecture and critical code, and remain close enough to the technology to challenge and unblock the team.
  • Partner with Product Managers, Designers, Data Scientists, and business teams from early discovery through launch and iteration.
  • Manage team capacity, headcount-planning inputs, and cloud and model usage costs (FinOps).
  • Remove blockers, align stakeholders, and communicate status, risks, and trade-offs to leadership.
  • Hire and onboard by defining profiles, conducting interviews, and calibrating the technical bar with Talent.
  • Promote an AI-first culture, knowledge sharing, and responsible AI practices across the chapter.

Desired Qualifications

  • Experience with Databricks, AWS, or MLflow in production environments.
  • Experience designing or leading evaluation and guardrail systems for large-language-model-based products.
  • Experience hiring across countries and in regulated sectors such as banking or fintech, or experience with financial products, operations, support, growth, or loyalty.
  • Interest in human-in-the-loop systems, AI trust, explainability, and responsible AI.

Digital wallet and Visa debit platform

Spin by OXXO is a fintech platform created by FEMSA to expand financial inclusion in Mexico. It offers a digital wallet and a Visa debit card (virtual and physical) that lets users send and receive money, pay bills, top up mobile airtime, and make purchases anywhere Visa is accepted, with deposits and withdrawals possible at OXXO stores. Spin operates under an electronic payment funds institution license through its CNBV‑registered subsidiary Compropago, earning revenue from commissions on cash deposits/withdrawals and select transactions. The service targets underbanked groups and includes the Spin Premia loyalty program; FEMSA plans to pursue a full banking license to offer more services in the future, while leveraging its broad retail network and partnerships to reach a large population.
