Job description

At CI&T, we help large enterprises transform the potential of AI into real business impact with AI Deployment, AI-native execution, and tech-integrated business solutions.

With 30 years of experience in technological transformation, we accelerate innovation with expertise in Agentic SDLC, Application modernization, Data & AI, Martech and Business strategy.

We are 8,000 CI&Ters across more than 25 countries, collaborating to build solutions with real impact. AI is already part of how we work, evolve, and innovate every day.

We are looking for a Senior Backend Engineer to design, develop, and scale high-performance backend services, integrating AI capabilities into modern distributed systems. This role combines strong backend engineering expertise with hands‑on experience in LLM integrations, Retrieval-Augmented Generation (RAG), and tool calling, leveraging technologies such as Go, Python, and Microsoft Azure.

The ideal candidate will bring a solid understanding of microservices architecture, event‑driven systems, distributed caching, and resilient service design to build reliable, scalable, and AI‑enabled backend solutions.

Responsibilities:

• Backend Architecture & Development: Design, develop, and maintain scalable backend services and APIs using Go and Python, applying microservices and event‑driven architecture principles to support high‑performance, distributed applications
• AI & LLM Integration: Integrate LLM capabilities into backend services, implementing RAG pipelines, tool calling, and AI orchestration patterns to enable intelligent, context‑aware application workflows
• Cloud Infrastructure & Performance Optimization: Build and integrate cloud‑native services on Microsoft Azure, implementing distributed caching strategies with Redis and optimizing service performance, scalability, and resource utilization
• Reliability & Distributed Systems Engineering: Design resilient backend architectures by implementing fault tolerance, retries, timeouts, and appropriate error‑handling strategies, ensuring reliable communication and execution across distributed services and AI‑powered workflows

Requirements:

• Languages: Go (Golang) and Python.
• SAP integration (required):S/4HANA and ERP via OData, IDocs, BAPIs, RFCs, APIs and middleware. Preferred: BTP, CPI, MDG, Variant Configuration
• Azure integration:APIM, Service Bus, Event Hubs, PostgreSQL, SQL, Entra ID, OAuth 2.0 and OIDC, Key Vault, networking, IaC
• Caching (required):Redis, distributed caching, cache‑aside, invalidation
• AI (lighter):LLM integration, tool calling, RAG, and AI coding tools (Codex, Claude Code, Copilot)
• Architecture: microservices, event‑driven systems, resiliency and retries

Our benefits include:

• Maternity and Parental leaves
• Mobile services subsidy
• Sick pay-Life insurance
• CI&T University
• Colombian Holidays
• Paid Vacations
