Lead AI Engineer

As a Lead AI Engineer you will lead Generative AI missions for our clients end-to-end from proof of concept to production acting as the technical reference on autonomous agents LLM deployment and cost-efficient GenAI architectures.

Heres what that looks like in practice: an empty repo a clients business need and a couple of weeks to prove the idea holds. You build the POC yourself the client is convinced now hundreds of their employees want it on their desk every morning. You add single sign-on and roles quotas so nobody drains the budget in an afternoon an evaluation harness that flags quality drift and pipelines that ship new versions without waking anyone up. Same person same architecture from first prototype to the service the client relies on.

Your key responsibilities

• AI Engineering & Agentic Workflows: design and lead the implementation of autonomous AI agents multi-agent orchestration (LangGraph CrewAI) and RAG pipelines with complex API integrations on client missions;
• Hybrid LLM Deployment: define deployment strategies across managed cloud AI services (Azure OpenAI AWS Bedrock GCP Vertex AI) and open-weight models (Llama Mistral) served on GPU infrastructure via vLLM or TGI;
• LLMOps Monitoring & Evaluation: design observability for GenAI applications quality latency hallucination detection using tools such as LangSmith Arize or Prometheus/Grafana;
• AI FinOps: control cost across client AI projects through token management prompt routing caching and GPU resource optimization;
• Technical Leadership: standardize containerization (Docker Kubernetes) with client teams mentor delivery engineers and communicate the technical vision to client stakeholders.
