Expect real agentic/RAG systems, real users, and evaluation data that tells you whether what you built actually works. Depending on fit and timing, you'll be matched to one of several active or upcoming client engagements - each with its own domain, constraints, and stack, but the same bar for engineering quality. You are a good fit for the role if... - You default to shipping, not just designing - a proactive, getting things done attitude in a fast-paced, client-facing setup where the interesting problems rarely come pre-scoped in a ticket. - You own the AI lifecycle end to end - ideation, architecture, delivery, evaluation - and you're comfortable being the technical voice in the room: proposing the approach, defending it with data (evals, latency, cost), and adjusting it when the data says you're wrong. - You can translate engineering constraints into terms a client stakeholder acts on - not just this won't scale but why, what the tradeoff actually costs them, and what a workable alternative looks like. - You treat client pushback as a design input, not an obstacle. Our expectations - 5+ years commercial Python experience, including 3+ years of hands-on GenAI/LLM engineering. - Solid engineering fundamentals: building scalable services/APIs (FastAPI, Flask, or Django), writing real test suites (pytest), clean and modular architecture. - Hands-on experience building RAG pipelines - retrieval, embeddings, vector search. - Working knowledge of agentic patterns: tool-calling, function-calling, multi-step reasoning workflows. - Strong prompt engineering skills, including structured outputs (JSON schemas, Pydantic, Instructor or equivalent). - Experience with at least one major cloud platform (AWS, Azure, or GCP), including its managed AI/ML services (e.g., Bedrock, Azure OpenAI). - An evals mindset - you think about relevance, consistency, latency, and cost as real engineering concerns. - High-proficiency written and spoken English. Welcome Skills - Experience with orchestration frameworks beyond the basics - LangGraph, LangSmith, LlamaIndex. - Hands-on with a specific vector database (Pinecone, Weaviate, Milvus, pgvector). - Experience building evaluation frameworks or golden-dataset pipelines. - Exposure to data pipeline work feeding AI systems. - Prior client-facing / consulting experience in a professional-services or consulting setup. Key tasks - Design and build Python services and APIs that wrap LLM-powered functionality. - Build and maintain agentic and RAG pipelines: retrieval, reranking, tool-calling, multi-step reasoning, structured outputs. - Care about quality beyond it works - evals, observability, and regression tracking. - Work directly with clients: translate fuzzy business requirements into architecture decisions, and explain technical tradeoffs to non-technical stakeholders. - Work across a distributed, multi-market team and client organizations.
