Role Summary:

Own end-to-end delivery of LLM systems and agentic workflows. You$B!G(Bll drive architecture and evaluation strategy, productionize services with reliability and guardrails, and mentor juniors while partnering with product and stakeholders.

What You Do

Lead POC $B"* (B pilot $B"* (B production for LLM/agent solutions (tool/function calling, planning, fallbacks).

Architect retrieval stacks (chunking strategies, hybrid search, metadata, re-ranking) and hallucination controls.

Design offline + online evaluations, golden sets, CI eval gates, and experiment frameworks for correctness, faithfulness, safety, and bias.

Implement confidence scoring and calibration (retrieval/LLM agreement, self-consistency, logprobs/entropy) with abstain/deferral and user-visible citations.

Optimize cost/latency/reliability (caching, batching, routing, distillation/quantization where useful).

Stand up secure APIs/services with observability, tracing, RBAC, and audit logs; uphold privacy and compliance requirements.

Advise on prompting vs. fine-tuning/LoRA; own model and vendor selection and trade-offs.

Mentor teammates; collaborate on roadmaps and stakeholder-facing KPIs.

Must-Have (Core)

4–8+ years in applied ML/data/engineering, with shipped LLM applications (RAG, agent/tool calling, structured extraction, domain QA).

Demonstrated ownership of eval strategy (golden sets, pass/fail thresholds, A/B) and integration of eval gates into CI/CD.

Hands-on confidence & calibration techniques and production abstention/deferral policies.

Deep retrieval experience (hybrid search, filters, re-ranking, chunking) and mitigation of hallucinations.

Strong Python engineering (FastAPI), SQL/data wrangling, containers, and observability (logs/spans/metrics).

Cloud experience (Azure/AWS/GCP) and vector/search tech (e.g., Azure AI Search, Elasticsearch, Pinecone/FAISS).

Track record of taking ambiguous business problems to measurable outcomes and shipping on timelines.

Nice to Have

Fine-tuning/LoRA, prompt routing, multi-agent orchestration (planner/critic/tool catalogs).

Advanced uncertainty: calibration curves, conformal methods, or LLM-as-a-judge with safeguards.

Distillation/quantization and model serving efficiency; GPU/CPU trade-offs.

Document AI (layout-aware models, VLMs), Snowflake/Databricks, Airflow/Prefect.

Safety/compliance leadership (red-teaming playbooks, model cards, DPIA/PIA inputs).

Domain expertise (e.g., insurance/finance/healthcare) and regulated data handling.
