AI Engineer – Contract

Up to £700 Per Day – Inside IR35

AI Connect are partnering with a leading financial services organisation to help them hire an AI Engineer to work on next-generation agentic AI systems. This role sits at the intersection of software engineering and applied AI building production‑grade, observable, and scalable agent‑based systems.

You’ll focus on designing and delivering agentic workflows, robust evaluation frameworks, and real‑world AI services for a digital assistant that processes millions of queries daily.

• Build and evolve agentic AI systems using frameworks such as Lang Graph, focusing on orchestration, state management, and multi‑step reasoning.
• Design and implement evaluation frameworks for LLM‑powered systems.
• Implement observability and monitoring for agentic workflows using tools like Langfuse, ensuring traceability, reliability, and performance insight.
• Develop production‑grade microservices using Python, FastAPI, and modern software engineering practices.
• Integrate LLM‑powered services with internal APIs, tools, and data sources to enable real‑world decision‑making and automation.
• Work closely with product, platform, and engineering teams to take agentic solutions from concept through to production.
• Contribute to architectural decisions around scalability, reliability, and system design for AI‑powered services.

• Strong experience as a Software Engineer or AI Engineer, with a clear focus on production systems rather than research.
• Excellent Python engineering skills, including experience building APIs and services with FastAPI (or similar frameworks).
• Solid understanding of microservices architecture, RESTful APIs, and distributed systems.
• Hands‑on experience with Lang Graph for building agentic workflows (this is a key requirement).
• Experience designing or working with LLM evaluation frameworks, testing strategies, and quality measurement.
• Experience implementing observability for LLM systems, ideally using Langfuse or similar tooling.
• Comfortable working in cloud environments (AWS experience is highly desirable).
• Strong communication skills and the ability to collaborate with cross‑functional teams.
