THE ROLE
We are looking for a highly skilled Machine Learning Engineer to join our Product Matching team, a critical function at the heart of Farfetch's competitive strategy. Our mission is to identify identical luxury products across a vast landscape of global competitors, using a sophisticated blend of heuristics and state-of-the-art machine learning. This is not just a standard matching problem. You will be tackling the unique challenges of luxury fashion—from discerning subtle differences in haute couture to understanding nuanced product descriptions from over 1,400 global partners. You will be instrumental in designing, building, and scaling our next generation of matching systems, leveraging a powerful tech stack that includes multimodal models, Large Language Models (LLMs), and Generative AI (including Google\'s Gemini). Reporting to a Software Engineering Lead, you will collaborate closely with Machine Learning Engineers, Data Scientists, and Product Managers to productionize cutting-edge research and directly influence the technical direction of our platform. If you are passionate about building robust, scalable AI systems that solve complex, real-world problems, this role is for you.
What You\'ll Do
* Design, build, and deploy robust, end-to-end MLOps pipelines on Databricks for complex models, including computer vision, NLP, and multimodal systems
* Fine-tune, optimize, and productionize Large Language Models (LLMs) and Generative AI solutions for tasks like product attribute extraction, semantic search, and similarity scoring
* Architect and manage large-scale data flows using PySpark, pulling from diverse sources like Azure Data Lake Storage (ADLS) and Google BigQuery to fuel our model training and inference services
* Develop and maintain scalable APIs and services to serve model predictions to internal business stakeholders, ensuring high availability and low latency
* Champion engineering best practices by writing clean, tested, and maintainable code, and developing reusable libraries and frameworks that accelerate the team\'s delivery
* Implement comprehensive monitoring and alerting for model performance and data drift to ensure our systems remain accurate and reliable over time
Who You Are
* A skilled software engineer with a passion for machine learning. You have proven experience building and deploying end-to-end ML-powered products in a production environment
* Proficient in Python and modern software engineering practices, including version control (Git), CI/CD, dependency management, and automated testing
* Experienced with distributed data processing. You have hands-on experience writing and optimizing complex data pipelines using Spark/PySpark
* Comfortable in a cloud-native environment. You have practical experience with a major cloud platform (Azure, GCP, or AWS) and its data services
* An excellent collaborator and communicator, able to work effectively in a cross-functional team of technical and non-technical members
Nice to Have
* Hands-on experience fine-tuning or deploying Large Language Models (LLMs), retrieval-augmented generation (RAG) systems, or other Generative AI technologies
* Familiarity with building multimodal AI systems that combine image, text, and structured data
* Deep expertise with the Databricks platform, including Delta Lake, MLflow, and model serving
* Experience with containerization technologies like Docker and orchestration with Kubernetes
Rewards & Benefits
* Health insurance for the whole family, flexible working environment and well-being support and tools
* Extra days off, sabbatical program and days for you to give back for the community
* Training opportunities and free access to Udemy
* Flexible benefits program
