About this role
Role Overview
- Design and evolve generative AI solutions for real business use, focusing on agents, prompting, RAG and evaluation.
- Design agents (agent workflows), tools (tool calling) and prompts for real-world use cases.
- Build/evolve RAG pipelines (ingestion, chunking, embeddings, retrieval, reranking, grounding).
- Define guardrails and policies: security, privacy, compliance, and hallucination prevention.
- Create evaluation strategy: metrics, datasets, automated tests, and acceptance criteria.
- Optimize quality and cost (latency, context, error rates, caching, model routing).
- Partner with engineering for production readiness (logging, auditing, monitoring, versioning).
Requirements
- Hands-on experience with LLMs and applied AI (e.g., agents, prompting, RAG).
- Strong foundation in Python and experimentation engineering (reproducibility, testing, metrics).
- Knowledge of retrieval techniques (vectors/embeddings, hybrid search, reranking).
- Experience or familiarity with quality evaluation (offline/online) and error reduction.
- Ability to communicate technical decisions clearly to both business and engineering stakeholders.
- Desirable (nice-to-have):
- Experience in the financial sector and/or with risk, fraud, credit, operations, or compliance processes.
- Experience with fine-tuning, evaluation frameworks and LLM observability.
- Experience working in regulated environments with auditability requirements.
