Your mission: turn architectural vision into real systems—working side by side with engineering teams to design, implement, and scale transition architectures that move us decisively toward our target state.This is not a distant governance role. You will be embedded in delivery—shaping solutions, unblocking teams, and ensuring that what we build today accelerates where we need to be tomorrow.From cloud adoption and integration patterns to domain evolution and engineering practices, you will be a critical bridge between architecture and execution across the organization.If you want to influence direction and see it implemented at scale, this is where it happens.What you’ll ownSolution Architecture LeadershipPartner directly with development teams to design and implement end-to-end solutions aligned with target architecture—balancing speed, scalability, and maintainability.Transition ArchitecturesDefine and evolve pragmatic transition states that enable incremental modernization without disrupting business continuity.Cloud Adoption EnablementDrive adoption of cloud-native patterns and services (AWS/Azure/GCP), ensuring solutions are designed for scalability, resilience, and cost efficiency.Integration & API StrategyStandardize and implement integration patterns (REST, events, messaging) that reduce coupling and enable faster cross-team delivery.Engineering Practices InfluencePromote and embed modern practices—CI/CD, DevOps, observability, resilience engineering—through direct collaboration with engineering teams.Domain & System EvolutionHelp teams decompose monoliths, define clearer service boundaries, and align systems with business domains.Architecture in ExecutionAct as a hands-on design authority within delivery cycles—participating in solution design, trade-off decisions, and technical problem solving.Cross-Functional CollaborationServe as a key connector between Architecture, Engineering, Security, Data, and Product—ensuring cohesive, end-to-end solutions.Governance that Enables DeliveryEstablish lightweight, pragmatic governance that accelerates decisions rather than slowing teams down.What makes this opportunity specialArchitecture that shipsYou won’t just define strategy—you’ll see it implemented in production.Embedded influenceWork directly with engineering teams, shaping real systems and outcomes.Transformation with momentumBe part of a fast-paced modernization effort with visible progress and executive backing.Enterprise impactYour decisions will influence systems used by millions across Mexico.What you’ve done (Required)12+ years in software engineering and architecture, with strong hands-on solutioning experienceProven experience working closely with development teams to deliver complex systemsTrack record implementing modernization initiatives (monolith to services, cloud adoption, API enablement)Strong expertise in distributed systems, APIs, and integration patternsPractical experience with cloud platforms (AWS, Azure, or GCP) and hybrid environmentsDeep understanding of system design trade-offs in high-scale, high-availability environmentsExperience embedding DevOps, CI/CD, and modern engineering practices into delivery teamsStrong stakeholder management with the ability to influence both engineers and executivesNice to haveExperience in financial services or regulated environmentsExposure to payments...
