• Implement and maintain Docker-based containerized environments for both development and production.
• Design and monitor event-driven systems using Kafka.
• Implement structured logging (Structlog/Logfire) and observability solutions (e.g., Datadog).
• Collaborate with the DevOps team on CI/CD pipelines using GitHub Actions.
• Contribute to Quadrant integration for deployment and operational alignment.
• (Optional) Provide support for Scala-based components, if applicable.

Required Skills & Experience

• FastAPI for building async APIs and microservices.
• Experience with Redis (especially asyncio clients) for state tracking and flow control.
• Strong understanding of MongoDB query patterns and schema design.

AI/ML Domain Knowledge

• Experience working with Large Language Models, including LLaMA (3.x preferred).
• Hands-on with LLM APIs such as OpenAI, Anthropic, etc.
• Experience with vector databases like Pinecone, understanding semantic search and embeddings.

Infrastructure & DevOps

• Experience in event-driven systems with Kafka (producers/consumers).
• Strong grasp of CI/CD using GitHub Actions.
• Familiarity with Quadrant for deployment orchestration.
• Comfortable with logging/monitoring tools such as Datadog.

Nice to Have

• Familiarity with Scala or willingness to learn it.
• Experience with Kubernetes or other orchestration tools.
