About the role

We are seeking a Senior GenAI / LLM Engineer to support a contract engagement with a leading financial services organization.

This role focuses on designing and building production-grade generative AI systems — from autonomous AI agents to advanced GraphRAG architectures — that power enterprise-scale decision-making. You will work at the forefront of applied AI, shipping real products integrated with complex financial data infrastructure.

What you'll do

* Build and deploy GenAI applications using foundation models and advanced architectures such as GraphRAG.

* Develop autonomous AI agents with modern agentic frameworks.

* Design and ship RAG and GenAI services using Python (FastAPI), Docker, and cloud platforms (AWS, Azure, or GCP).

* Build scalable REST APIs that power LLM-driven applications integrated with enterprise data sources.

* Implement LLM evaluation frameworks — using tools like Ragas, LangSmith, or custom benchmarks — to measure answer relevance, groundedness, and hallucination rates.

* Apply LLMOps/MLOps best practices: CI/CD pipelines, prompt versioning, automated testing, and monitoring of latency, cost, and response quality.

* Build systems leveraging embeddings at scale, knowledge graphs, and ontology extraction.

* Collaborate across engineering teams, mentor developers, and help drive innovation in GraphRAG and agentic AI architectures.

What you'll bring

* Degree in Computer Science, AI/ML, or a related field.

* 5+ years of AI/ML-focused software engineering experience.

* Production experience building LLM-based or agentic AI systems.

* Strong expertise in Python and modern AI frameworks.

* Hands-on experience with embeddings, knowledge graphs, ontology extraction, and advanced RAG/GraphRAG implementations.

* Full-stack development and deployment experience (Python back end + modern front end).

* Proven experience deploying AI workloads to AWS, Azure, or GCP.

* Familiarity with LLMOps/MLOps tooling and model evaluation frameworks.

* Strong problem-solving, communication, and collaboration skills.
