Senior AI Engineer – Agentic Platforms/£800–900/day/Outside IR35 Remote (UK)/6 months

AWS/.Net/React

We’re partnering with a market leader as they build out a next-generation AI platform at the core of their product suite.

They’re looking for two Senior AI Engineers to design and deliver production-grade, agentic systems, this is not research or proof-of-concept work. You’ll be building scalable, real-world AI solutions embedded directly into a live platform.

The focus is on developing intelligent, self-learning workflows, multi-agent systems, and AI-driven automation to support professionals in managing leads, workflows, and customer interactions.

You’ll work closely with Product, Architecture, and Data teams to shape and deliver the underlying platform, with a strong emphasis on engineering quality, scalability, and commercial impact.

- Key responsibilities:

- Designing and building agentic architectures and multi-agent workflows

- Developing AI-driven automation and decision-support systems

- Building and scaling cloud-native services across AWS (Lambda, ECS/EKS, S3)

- Working across the full stack, including TypeScript/JavaScript and React

- Integrating LLM platforms (OpenAI, Anthropic) into production systems

- Driving best practices across observability, evaluation, and reliability

We’re particularly interested in engineers who:

-Have built real-world AI or agent-based systems (not just prototypes)

- Are comfortable working full-stack, with solid React experience

-Bring strong AWS and scalable system design experience

-Can operate autonomously and contribute to technical direction

-Take a pragmatic, delivery-focused approach

This is a high-impact opportunity to help define the foundations of a core AI platform in a fast-moving, well-backed environment.
