Formación

• Proficiency in machine learning, ML engineering, MLOps, software engineering and LLMs in a commercial production environment.
• Demonstrated knowledge and application of machine learning across training, evaluation and inference and model monitoring, using both structured and unstructured data such as image and text.
• Proficiency in Python, SQL and other relevant ML technologies. You don’t need to know every technology we use, but you do need to be able to design and create high-quality, maintainable software.
• The ability to identify the most appropriate machine learning approaches and tools for a commercial application or opportunity.
• Clear written and verbal communication skills, with the ability to work collaboratively across teams and with a range of business stakeholders.
• The ability to independently and collaboratively lead the design, scoping and delivery of key feature slices to a high standard and within agreed timelines.

Responsabilidades

• Design, implement, test, evaluate, deploy and monitor AI/ML products, pipelines and services using Python, modern ML frameworks such as PyTorch, AWS and cloud-native technologies.
• Apply engineering best practices including test automation, CI/CD, refactoring, observability, Docker and infrastructure as code to build and operate reliable AI/ML products.
• Develop, test and maintain real-time and batch data engineering pipelines using technologies such as Airflow, SQL, BigQuery and Kafka.
• Establish automated evaluation and monitoring systems to track AI product and feature performance, detect drift and ensure quality at scale.
• Implement and optimise ML models for ranking, relevance and retrieval using embeddings, transformers and LLMs in production environments.
• Measure and optimise third-party models through appropriate evaluation and optimisation approaches.
• Own model lifecycle management, including versioning, deployment and CI/CD integration for reproducible experimentation and delivery.
• Contribute to discussions, design and delivery of ML platform capabilities that accelerate delivery across teams.
