Requirements:
- Strong Python (typing, tests, packaging) and web/service basics (FastAPI, Docker).
- Hands-on building LLM apps with one or more: LangChain, LangGraph, AutoGen, Dify (or equivalents).
- RAG end-to-end experience: corpus prep → embeddings → retrieval → re-rank → context assembly → measurable gains.
- Evaluation mindset: design offline eval sets and release gates; reason about faithfulness vs relevancy; control p95 latency & $/session.
- Cloud proficiency in AWS or Azure (using at least one in production).
- Comfort with observability (OpenTelemetry/LangSmith/Prometheus/Grafana or similar).
- English B2+; clear written & verbal client communication.
Responsibilities:
- Design & build LLM applications: RAG over client KBs, multi-tool/agent graphs, prompt strategies, and voice UX (STT/TTS).
- Implement retrieval & data flows: ingestion, chunking, metadata/embeddings, hybrid retrieval, re-ranking, caching.
- Own evaluation & quality: latency/cost budgets, A/Bs.
- Automate with n8n (or similar): connect services, data, and back-office workflows; expose reliable admin ops for non-engineers.
- Ship pipelines: Airflow for orchestration; dbt for transformations/semantic layer where relevant.
- Productionize: tracing/observability, feature flags, safe rollouts, secrets & config hygiene.
- Collaborate with clients: discover scope, explain trade-offs, demo progress; optional presales spikes/estimates.
Nice to have:
- Vector DBs: pgvector, Qdrant, Pinecone, Azure Cognitive Search (vector); rerankers (BGE/monoT5/Cohere/ColBERT).
- Voice: Azure Speech, Whisper; VAD/barge-in, turn-taking logic.
- Data stack: dbt, Airflow, event streams; data contracts.
- Workflow: n8n design for non-tech ops; governance of low-code automations.
- Frontend for AI UX (React/Next.js, TypeScript).
- Compliance awareness for EdTech (FERPA/COPPA) and Healthcare (HIPAA/GDPR).
