AI Engineer (Contract) – £500/day Outside IR35

📍 Canary Wharf, London (3 days onsite)

🇬🇧 UK-based applicants only

We’re looking for experienced AI Engineers who think holistically, automate relentlessly, and know how to turn modern AI capabilities into production-grade, high-impact applications.

Our AI organisation is building real-world AI products that deliver business value at speed. This role is ideal for seasoned engineers who combine strong software engineering fundamentals with a pragmatic, hands-on approach to AI tooling and infrastructure.

What you’ll be doing

* Designing, building, and maintaining production-grade AI applications using modern engineering practices (CI/CD, testing, observability, cloud-native design).

* Developing reusable AI platforms and tools (e.g. conversational bots, AI-powered search, unstructured data processing, GenAI solutions).

* Working in cross-functional, embedded teams with business stakeholders to rapidly deliver AI solutions to high-priority problems.

* Evaluating and integrating AI tools and frameworks (LLMs, vector databases, RAG, AI agents) into robust, scalable systems.

* Championing automation across the full AI lifecycle—from data ingestion and preprocessing to deployment and monitoring.

* Collaborating closely with data scientists, product managers, and engineers to ensure reliable end-to-end delivery.

* Contributing to internal tooling, documentation, and best practices to scale AI engineering capability.

What we’re looking for

* Several years of professional software engineering experience, with a track record of shipping complex systems to production.

* Strong Python skills and experience building APIs, microservices, and backend systems.

* Solid understanding of software architecture, cloud infrastructure (AWS and/or Azure), and modern DevOps practices.

* Hands-on experience integrating ML models into production systems (LLMs via APIs, fine-tuning, RAG, embeddings, agents).

* Ability to move fast without compromising on code quality, testing, and operational excellence.

Nice to have

* Experience with tools such as LangChain, LlamaIndex, Haystack, Hugging Face, Weaviate, CrewAI, AutoGen, or similar.

* Hands-on work with Retrieval Augmented Generation, AI agents, and agent orchestration frameworks.

* Experience working with unstructured data (documents, conversations, images).

* Background in platform engineering, internal developer tools, or forward-deployed/embedded team models.

* Experience building reliable, production-grade GenAI applications.

Contract details

* Rate: £500 per day

* Location: Canary Wharf, London (3 days onsite per week)

* Eligibility: Must be UK-based
