Artificial Intelligence Engineer - Java/Python

Job description

AI Engineer (LLMs, Python & Java)

Bracknell (Hybrid)

What if you could own and build the AI capability from the ground up in a scaling, purpose-driven tech company?

We’re hiring the first dedicated AI Engineer to join a fast-growing (~200 people) SaaS organisation making a real-world impact. This is a rare opportunity to shape the AI strategy, design production-grade systems, and bring cutting-edge LLM-powered solutions into a live product environment.

The Role

You’ll sit at the intersection of AI, backend engineering, and cloud systems, designing and deploying intelligent features that directly impact users.

Expect to:

• Design and implement LLM-based applications (RAG pipelines, agents, copilots)
• Build scalable backend services using Python and Java
• Integrate AI into existing cloud-native SaaS platforms
• Own the full lifecycle: experimentation → prototyping → production
• Optimise model performance, cost, and latency in real-world environments
• Collaborate across engineering, product, and data teams to identify high-impact AI use cases

What We’re Looking For

• 5+ years in software engineering, with strong experience in Python and/or Java
• Hands-on experience working with LLMs (prompt engineering, fine-tuning, embeddings, vector databases, RAG)
• Experience building and deploying applications in cloud environments (Azure preferred, AWS/GCP also considered)
• Strong understanding of APIs, microservices, and distributed systems
• Familiarity with tools like Docker, Kubernetes, and CI/CD pipelines
• Experience working with data stores (SQL/NoSQL) and large datasets
• Bonus: experience with AI frameworks (LangChain, LlamaIndex, etc.)

Why Join?

• Be the first AI hire — real ownership and influence
• Work on meaningful, tech-for-good products
• Modern stack, forward-thinking leadership, strong growth trajectory
• Opportunity to define architecture, tooling, and best practices

Package

• Salary up to £95,000 (depending on experience)
• Bonus + private medical
• Bracknell-based hybrid working
