Senior Platform Engineer: AI-First Backend Architect

DXC Technology; Ciudad de México; Presencial; MXN 900.000 - 1.500.000; Jornada completa

Descripción de la vacante

DXC Technology in Mexico City seeks a senior backend engineer to assess and decompose a 34-microservice architecture, design modern Python/TypeScript stacks, and lead AI-driven replacements.

You will own database redesign from Oracle MSSQL to PostgreSQL, implement data quality pipelines, and replace rigid business rules with AI-augmented workflows. This role emphasizes API-first design, verification loops, and migration pathways with observable systems using Grafana and ELK.

Formación

• Assess and decompose the existing 34-microservice architecture to identify simplification and replacement opportunities.
• Design and build next-generation backend services using modern Python / TypeScript stacks with LLM-augmented business logic.
• Own database architecture redesign - migrating from Oracle RDS / MSSQL to modern schemas (PostgreSQL, event stores) that are AI-queryable and analytics-ready.
• Build data quality frameworks and validation pipelines that ensure AI systems work from reliable, well-structured data.
• Replace rigid Saga / Orchestrator chains with AI-driven workflow engines and simpler event-driven patterns.
• Develop LLM-powered solutions to replace hard-coded costing rules, financial calculations, and allocation logic.
• Operate in the Intent → Generate → Verify → Decide → Document loop, owning decisions on irreversible, money-touching, or outward-facing logic.
• Build migration pathways (strangler fig, parallel running) to transition from legacy to modern architecture without service disruption.
• Performance tuning and observability using Grafana, Kibana, and the ELK stack.
