Responsibilities
- Applied LLM Engineering: Design and ship micro-services that combine retrieval augmented generation (RAG), prompt pipelines, and tool calling agents for use-cases such as summarisation, Q&A, topic-detection, and sentiment scoring
- Embeddings & Retrieval: Build ingestion jobs that chunk, embed (OpenAI / HuggingFace / in-house), and index millions of calls and emails into Elasticsearch or a vector store; optimize latency, recall, and cost
- Evaluation & Safety: Own offline + online eval harnesses (BLEU, ROUGE, human-in-the-loop, red-teaming) and put model guard-rails in place (PII filtering, toxicity checks)
- Fast Iteration: Pair with PMs & designers to run A/B tests, ship weekly behind feature flags, and iterate based on usage signals
- Technical Depth: Contribute Python production code (FastAPI/Ray) plus tests; review PRs, write design docs, and champion best practices for other product squads integrating LLMs
Qualifications
- 2+ years total engineering experience with at least 1 year building or integrating LLM/GenAI features (e.g. OpenAI, Bedrock, Claude, Llama2)
- Solid Python skills (typing, async, pytest) and familiarity with one ML/LLM framework: PyTorch, Hugging Face Transformers, or LangChain/LlamaIndex
- Hands‑on with vector databases / search stacks (Elasticsearch k‑NN, Pinecone, FAISS, or equivalent)
- Proven backend fundamentals: REST/GraphQL, distributed queues (Kafka/SQS)
- Understanding of prompt engineering, temperature / top‑p tuning, embeddings, and token‑cost optimisation
- Comfort with reading research papers / blog posts and rapidly prototyping ideas
- Clear written & verbal communication; able to explain trade‑offs to both engineers and non‑technical stakeholders
- Exposure to Ray, Triton, or other high‑throughput inference stacks is a plus
