Fortalecer a confiabilidade dos sistemas agênticos:
- Implementar guardrails, mecanismos de validação e observabilidade de agentes (LangFuse e similares).
- Ajudar a lidar com o não-determinismo em produção, para que comportamento probabilístico não vire incidente.
Trabalhar com MCPs e integrações entre ferramentas:
- Construir e evoluir MCPs internos (dbt, Metabase, Slack) que servem múltiplas iniciativas e padronizam o acesso a fontes para agentes.
Participar das decisões técnicas avaliando trade-offs:
- RAG vs LLM Wiki, heurística vs LLM, custo vs latência vs qualidade.
- Conduzir experimentos comparativos, documentar a recomendação e decidir em conjunto com as pessoas mais experientes do time.
Participar dos code reviews:
- Aponte trade-offs de performance, custo de tokens, manutenibilidade e impactos nos times consumidores.
Colaborar com Data Platform e Analytics Engineering:
- Discutir contratos, latência, governança e como os produtos da plataforma se conectam ao consumo real dos times.

- Monitoramento e observabilidade;
- Soluções de Cloud;
- Construção de integrações entre sistemas (APIs, webhooks, MCPs).
Requirements
- Conteinerização e deploy com Docker e Kubernetes;
- CI/CD;
- Sistemas agênticos em produção — engenharia de prompts, orquestração de agentes, tools, sub-agentes, paralelismo, retry e estratégias de fallback;
- MCP (Model Context Protocol) — construção ou consumo de MCPs para padronizar acesso de agentes a fontes de dados e ferramentas;
- RAG e arquiteturas alternativas — quando aplicar RAG, quando aplicar síntese prévia (estilo LLM Wiki), trade-offs entre as duas;
- Avaliação de sistemas de AI — LangFuse, métricas de qualidade, custo e latência de agentes; design de evals para sistemas não-determinísticos;
- Gestão e integração com plataformas de visualização (Metabase, Looker, Tableau) — APIs, automação de questions, dashboards;
- Skills do Claude Code — criação de skills customizadas para automatizar fluxos do time;
- Infraestrutura como código.
