Frontend
- React 18 + TypeScript + Vite — component architecture, hooks, lazy loading
- Server-Sent Events (SSE) or WebSocket — real-time streaming UIs
- ReactFlow / XYFlow — interactive node-based graph editors
- State management (Zustand or Redux) + server-state (TanStack Query)

Additional Skills

- vLLM or TGI — on-prem LLM model serving and optimization
- mem0 or similar — persistent agent memory systems
- A2A / MCP / AG-UI — emerging agentic interoperability protocols
- GraphQL — schema design, client integration
- OAuth2 / SAML / OIDC — enterprise SSO integration
- Ontology modeling — entity taxonomies, relationship schemas for engineering domains
- Pytest — async test patterns, fixture-based testing

Qualifications

- 4+ years professional software engineering experience
- 2+ years working with LLMs, agent frameworks, or ML systems in production
- Strong async Python and modern React/TypeScript skills
