About the Role We are seeking a Senior ML Engineer with strong experience across Applied AI, Machine Learning and MLOps to help build and modernise a new AI platform. This role sits primarily between Applied AI and MLOps, with backend/platform engineering experience supporting the productionisation of ML capabilities. You will work on both building new ML components from scratch and re-engineering existing capabilities into reliable, observable and production-ready systems. The focus is not purely on model development or experimentation. You should have genuine experience productionising, deploying, evaluating and operating AI/ML applications, with a strong understanding of the challenges encountered when running these systems in production. You will work on modernising existing NLP, generative AI and other ML capabilities while creating an architecture that makes new models easier to integrate, evaluate, monitor and deploy.
