Collaborate closely with AI and platform engineers to expose agentic capabilities via intuitive UI/UX patterns

Build backend systems to support scenario authoring, misconfiguration detection, and real-time validation workflows

Contribute to the canvas-based WYSIWYG editor, helping users bridge natural input with visual infrastructure diagrams and deployment artifacts

Participate in architecture and system design discussions, with an eye toward performance, maintainability, and extensibility

Support DevOps and local development setups (Docker, Kubernetes, Azure DevOps), CI/CD pipelines, and observability instrumentation

Solid knowledge of relational data modeling and PostgreSQL database management.

Exposure to LLM integration, including function/tool calling, context injection, or orchestration systems

Strong debugging, testing, and system design skills in production-grade environments

Qualifications

Experience building canvas-based editors, graph tools, or low-code platforms

Familiarity with LangGraph, semantic retrieval frameworks (e.g., Weaviate, PGVector), and RAG pipelines
