OverviewWinning together, and sharing the magic. The energy behind the brand is infectious, and as we grow, we are always looking for extraordinary talent who want to be part of our success and help drive our limitless ambitions.The AI & ML Engineering team accelerates the adoption of AI across the business, championing innovation while ensuring our machine learning products are robust, scalable, and cost-efficient. We enable teams to solve problems using existing AI tools where possible and build custom solutions when needed. Our remit spans AI enablement, agentic systems development, and "conventional" ML engineering for non-GenAI applications like recommender systems. This is a highly visible, hands-on engineering role with a strong focus on pragmatic, production-ready solutions that drive real business impact. This role and team collaborate closely with the wider Data team (Data Science, Core Data Engineering) and the wider organisation (Technology, Legal, Information Security) to onboard/develop & scale AI applications.ResponsibilitiesPartner with stakeholders to scope problems and identify the right solution — whether leveraging existing AI tools or building custom workflows & solutions.Design and implement agentic systems using techniques spanning RAG, grounding, prompt engineering, and orchestration on a GCP-first stack.Build and maintain production ML pipelines and services for non-GenAI use cases (e.g. recommender systems, customer segmentation models, marketing optimisation modules), leveraging supervised, unsupervised and/or econometric modelling approaches.Develop APIs and microservices for AI/ML solutions, ensuring security, scalability, and observability.Implement CI/CD for ML services, write infrastructure as code, and monitor for model/data drift and performance.Establish robust guardrails for safe AI usage, including prompt security, practical evaluation frameworks, and compliance with privacy regulations.Drive and evangelise best practices, reusable templates, and documentation to scale AI/ML delivery across the business.Collaborate with data engineers, data scientists, front & back-end engineers, product managers, legal & infosec colleagues to deliver impactful solutions end-to-end.QualificationsBachelor's or Master's degree in Computer Science, Engineering, or related field.Strong Python engineering skills (FastAPI, testing, typing) and experience with cloud-native development (GCP preferred).Hands-on experience with GCP Vertex AI (model endpoints, pipelines, embeddings, vector search) or equivalent cloud-native ML platforms (e.g. AWS SageMaker, Azure ML) and agent orchestration frameworks such as LangChain and LangGraph.Solid understanding of MLOps: CI/CD, IaC (Terraform), experiment tracking, model registry, and monitoring.Proven experience deploying and operating ML systems in production (batch and real-time).Familiarity with RAG architectures, prompt engineering, and evaluation techniques.Strong grasp of security, privacy, and governance principles (IAM, secrets, PII handling).Excellent communication skills and ability to work with non-technical stakeholders.Desirable additional experience: vector databases and retrieval strategies; knowledge of recommender systems and ranking models; familiarity with LLM evaluation tools (e.g., RAGAS, TruLens, LangSmith, Arize); exposure to feature stores, data lineage, and observability stacks; experience in e-commerce or retail environments; ability to weigh build/build/configure decisions in the LLM space.About Charlotte Tilbury BeautyFounded by British makeup artist and beauty entrepreneur Charlotte Tilbury MBE in 2013, Charlotte Tilbury Beauty has revolutionised the face of the global beauty industry by de-coding makeup applications for everyone, everywhere, with an easy-to-use, easy-to-choose, easy-to-gift range.
