Job Description

We are looking for Software Engineers, ML Engineers, AI Engineers, or Data Scientists with a hacker mentality and a strong background in production-grade AI applications. Experience in the use of LLMs (e.g. GPT, Claude, Mistral, etc.) is essential, ideally with familiarity in Agentic environments.
Luminance is a market-leading UK AI company revolutionising the legal sector. Today, Luminance's technology is helping over 700 customers in 70 countries globally, has received two Queen's Awards and was highlighted on the Forbes AI 50, one of only three UK business on the list in 2025.
With ambitious growth plans, we need bright, passionate, and driven people to achieve these goals. From day one, you will be building features and tools for some of the world's largest businesses. Speed and quality of execution are a must.
You will be working on AI prototypes that combine multiple components to reliably solve complex tasks in nuanced scenarios. You will be expected to integrate novel agentic technologies (e.g. memory usage and personalization) and productionise your solutions into reusable libraries and frameworks.
If you are excited about this role but your skill or experience doesn't perfectly align with the job description, we encourage you to apply anyway. Your drive to build and learn is by far the most important requirement for any applicant to Luminance!
