Descrição da vaga

🚀 Are you passionate about building AI solutions and distributed systems?

We’re looking for an AI Agent & Full-Stack Engineer to design and build AI agents, RAG solutions, and cloud-native services. You’ll work across the development lifecycle—from agent orchestration and model integrations to backend services, user interfaces, and cloud deployment.

What you’ll do

  • Design and build AI agents, agent loops, tools, and orchestration workflows.
  • Develop RAG solutions using effective chunking strategies, metadata filtering, and controlled vocabularies.
  • Implement prompt engineering, versioning, evaluation, and model reasoning frameworks.
  • Build APIs and integrations following OpenAPI standards.
  • Design event-driven backend services using Java, Spring Boot, Kafka, and MongoDB.
  • Develop operational dashboards and user interfaces with React and TypeScript.
  • Build and deploy cloud-native solutions on AWS and Kubernetes.

What we’re looking for

AI and agent engineering

  • Strong Python skills, including asyncio and asynchronous programming.
  • Experience with agent architectures, agent loops, tool design, and orchestration.
  • Knowledge of MCP (Model Context Protocol), RAG, prompt engineering, and evaluation.
  • Familiarity with OpenAI and/or Anthropic frameworks and best practices.
  • Knowledge of AWS Bedrock, AgentCore, and orchestration frameworks such as Strands.

Backend and distributed systems

  • Strong experience with Java 17+ and Spring Boot.
  • Experience with MongoDB, including document modeling, transactions, and change streams.
  • Experience with Kafka, including partitioning, consumer groups, dead-letter queues (DLQs), and delivery guarantees.
  • Understanding of event-driven architectures and distributed systems patterns

Frontend and cloud

  • Experience with React and TypeScript.
  • Familiarity with Kubernetes and AWS cloud services.

Nice to have

  • Experience building enterprise AI platforms or agent-based applications.
  • A strong understanding of consistency and reliability patterns in distributed systems.
Interested in combining AI, full-stack development, and distributed architecture to build innovative solutions? We’d love to hear from you!
