📋 Description

• Develop specialist agents coordinated by a supervisor, with agency loops (ReAct) and an auditable decision log. • Build MCP servers that connect agents to operational APIs (.NET) and ML models via OpenAPI contracts. • Implement the MCP Host using LangChain / Semantic Kernel and LLMs via Azure OpenAI. • Implement Human-in-the-Loop (HITL) for high-impact decisions. • Ensure agentic security: per-agent identity (OAuth2), tool-level scopes, idempotency, sanitization against prompt injection, and prevention of PII leakage. • Version prompts (PromptOps) and instrument agent observability (LangSmith or similar). • Integrate with event-driven architecture (Azure Service Bus / Kafka).

🎯 Requirements

• Bachelor's degree in Data Science, Computer Science, Statistics, Engineering, Mathematics, Economics, or a related field. • English or Spanish proficiency (international client). • Strong programming skills (Python and/or C#/.NET) — testing, contracts, version control, readable code. • Experience building applications with LLMs: tool/function calling, agent orchestration, prompt engineering, and handling nondeterministic behavior. • Systems integration: consumption and design of REST APIs (OpenAPI/Swagger), OAuth2 authentication, idempotency, webhooks/callbacks. • Secure data access from LLMs — e.g., natural language → query with scope control, validation, and auditing. • Familiarity with LLM application security: prompt injection, data leakage, and permission control per tool.

🏖️ Benefits

• Remote work. • 8 hours per day (168 hours per month). • Time bank with quarterly settlement (payment for accrued positive hours). • Variable compensation after 4 months of contract. • Flexible benefits card: monthly meal allowance of R$ 700.00 (Flash card). • Paid time off: 7 consecutive days after 1 year of contract; 15 days after 2 years; 21 days between years 5 and 7; and 30 days after 8 years of contract. • Birthday day off (one paid day off during your birthday month). • Partnership with Wellhub. • Partnership with Open English. • Partnership with FIAP. • Partnerships with clinics and psychology services.
