Lead Software Engineer

Mastercard Mastercard · Fintech · Mexico City, Mexico · Engineering

Lead Software Engineer for Mastercard's CNPF Data & AI organization, focusing on building next-generation intelligent, agentic products and platforms. This hands-on technical leadership role requires strong software engineering fundamentals and practical experience in production AI systems, including designing and delivering secure, scalable, and reliable agentic applications that reason, orchestrate tools, and interact with enterprise systems.

What you'd actually do

  1. Lead hands-on architecture, design, and implementation of agentic applications, AI-powered services, and platform capabilities from concept through production
  2. Define engineering patterns and best practices for production AI systems, including evaluation, monitoring, guardrails, resiliency, cost control, and rollback strategies
  3. Drive end-to-end software delivery across the SDLC, from discovery and prototyping to testing, release, and production operations
  4. Use engineering tools to accelerate design, coding, testing, documentation, troubleshooting, and delivery while maintaining strong engineering judgment and code quality standards
  5. Champion an AI-enabled SDLC by improving developer workflows, automation, test generation, code review quality, release confidence, and team productivity
