Software Engineering Specialist Artificial Intelligence

Software Engineering Specialist Artificial Intelligence

Vice-Presidency: CHIEF INFORMATION OFFICER Directorate: DIR INTELIGÊNCIA ARTIFICIAL Work Location: Remote

About the Role

You are not here to just "implement models." You are here to redefine engineering. We are building the foundation of a new era. In our Artificial Intelligence Directorate, we don't treat AI as a technological "add-on" or an isolated chat; we build native AI solutions. Our focus is on architecting platforms, products, and ecosystems where intelligence is the central engine, not an accessory.

We are looking for professionals with an AI-Native mindset. People who want to get their hands dirty building agent architectures, multi-modal systems, and high-performance infrastructures that support the scale of the largest technology and telecommunications company in the country.

The Challenge

The role of the AI Engineer here is that of an elite builder. You will operate at the intersection of elegant code and computational intelligence, transforming the "state of the art" into the "state of production." Forget purely experimental work. Our focus is on high-impact delivery:

• Build from Scratch: Create platforms and products that are born with AI at their core.
• Orchestrate the Future: Implement autonomous agent architectures and advanced RAG systems that solve real problems in milliseconds.
• Scale Intelligence: Ensure our solutions are resilient, secure, and capable of processing massive volumes of data efficiently and at low cost.

Responsibilities and Duties

We are looking for a Software Engineering Specialist to be the ultimate technical reference within our AI Engineering Platform structure. You will be responsible for ensuring that the "core" of our AI and Agent solutions is world-class, tackling complex challenges of scalability, low latency, and integration of large-scale language models.

Responsibilities

• Design and sustain high-availability complex architectures for APIs and services supporting Vivo's AI ecosystem.
• Lead the definition of coding and design standards (Design Patterns, Clean Architecture), serving as a reference for Senior and Mid-level developers.
• Optimize the performance and costs of cloud services, ensuring efficiency in processing large volumes of data and model calls (LLMs).
• Practical technical mentorship: Conduct critical code reviews and pairing sessions to elevate the team's technical level.
• Develop critical components and internal SDKs to be consumed by multiple AI squads.
• Ensure system resilience through advanced strategies for observability, fault tolerance, and infrastructure automation.

Requirements and Qualifications

Requirements (Technical Depth)

• Extensive experience with backend development using Node.js and Nest.js.
• Deep mastery of microservices architecture, messaging patterns, and asynchronous communication (Event-driven, WebSockets, gRPC).
• Expertise in Kubernetes (AKS): resource configuration, horizontal/vertical scaling, and large-scale container management.
• Advanced knowledge in Cloud Native (Azure): Event Hub, Cosmos DB, Redis, and caching strategies.
• Solid experience in Security: Implementation of complex authentication flows (OAuth 2.0, OIDC) and data protection.
• Mastery of Infrastructure as Code (Terraform) and infrastructure automation for critical production environments.
• Strong foundation in Databases: Query optimization, NoSQL modeling, and consistency management.

Specialty Differentiators

• Deep experience with LangChain, LangGraph, and Autonomous Agent orchestration.
• Technical knowledge in Prompt Engineering and RAG (Retrieval-Augmented Generation) to optimize LLM responses.
• Familiarity with APM and Observability tools (Dynatrace, Prometheus, Grafana) for root cause analysis in distributed systems.

Expected Profile

• Hands-on and Mentor: You love code but enjoy teaching and raising the team's technical bar.
• Focus on Excellence: Dissatisfaction with solutions that "just work"; always seeking the best architecture and performance.
• Problem Solving: Analytical ability to diagnose complex technical bottlenecks in production.
• Technical Communication: Skill in clearly explaining complex architectural decisions to the engineering team.
