Strong software engineering background in Node.js with TypeScript, with ability and motivation to work deeply in Python services
Proven experience building production AI/LLM applications, including multi-agent workflows and orchestration patterns
Strong understanding of AI framework selection and practical trade-offs (LangGraph and related ecosystem tools are a strong advantage)
Experience developing and operating microservices with multiple internal and external integrations
Strong experience with Kubernetes and containerized deployments (Docker)
Experience with Infrastructure as Code (Terraform or equivalent)
Experience with event-driven architectures, preferably including event sourcing patterns

Experience with AWS and Azure, and practical cloud-agnostic architecture design
Experience designing solutions that can be deployed in private cloud environments
