Graduate Machine Learning Engineer, AI

Work on exciting public sector projects and make a positive difference in people’s lives. At Zaizi, we thrive on solving complex challenges through creative thinking and the latest tools and tech.

As a Graduate Machine Learning Engineer, you’ll start building the skills to research machine learning models and evaluate how they can be applied within our specialist domain, working alongside and learning from a small team who deliver AI capabilities for the UK government. You'll be curious about all flavours of AI from classical ML to the latest generative and adversarial techniques and keen to learn as the field moves. You'll bring a foundation in software engineering from your degree alongside your ML knowledge, and be eager to get hands‑on with research, experiment under guidance, and see how new approaches translate into practical capability for our customers. You'll work closely with, and be mentored by, a small, high‑performing team of engineers and researchers, contributing ideas and building new skills as you go.

Our work culture is inclusive, modern, friendly, and democratic. We look for bright, positive thinking individuals with a can do attitude and a genuine appetite for learning. Our people enjoy challenging themselves to be the best at what they do, if that sounds like you, you'll fit right in! And the work itself matters: you'll be helping to keep the UK safe.
