This creates better outcomes for members, lower claims, and shared value for clients and society. \n\nDiscovery has one of the most diverse data assets in financial services and healthcare in the world, spanning health, wellness, lifestyle, driving, investments, and life insurance. This creates a unique opportunity to use advanced analytics, causal inference, machine learning, and artificial intelligence to improve member outcomes, strengthen operational performance, and support more personalised products and services.\n\nAbout the Data Science Lab\n\nThe Data Science Lab (DS Lab) is a specialist team that solves high-impact problems across Discovery Health and the broader Discovery Group. Using large-scale structured and unstructured data, the team develops models, experiments, decision systems, and AI-enabled solutions that create measurable business and member value, like the Personal Health Pathways (PHP) programme.\n\nThe DS Lab partners with teams across Discovery and organisations such as Google, Quantium Health, and world-renowned tertiary institutions to advance personalisation, causal inference, optimisation, and AI. The team also contributes to the Vitality AI platform, delivering scalable capabilities across Discovery, Vitality UK, USA and international partner markets. Junior data scientists gain exposure to cutting-edge work, experienced mentors, and the opportunity to contribute to solutions with real-world impact.\n\nKey Purpose\n\nThe Junior Developer - AI Engineering role plays an important role in supporting the development, deployment, operation, and continuous improvement of AI and machine learning solutions across the Data Science Lab (DS Lab) portfolio. This role is designed for early-career software, data, platform, or AI engineers who are passionate about building production-grade technology and developing expertise in modern AI engineering practices. Working alongside Senior ML & AI Engineers, Data Scientists, Product Teams, and Platform Engineers, the successful candidate will contribute to the engineering work required to move AI solutions from experimentation into reliable and scalable production systems.\n\nThe role provides exposure across software engineering, machine learning engineering, cloud platforms, MLOps, Generative AI, data engineering, observability, and AI operations. The successful candidate will gain hands-on experience building deployment pipelines, supporting model-serving infrastructure, integrating AI services, monitoring production systems, and improving engineering processes across multiple AI products. This role is not focused on developing statistical models or conducting research. Instead, it focuses on engineering, automation, operational support, platform development, and production readiness for AI systems.\n\nThe successful candidate will help contribute to the engineering foundations that enable reliable deployment, operational excellence, observability, and continuous improvement across Discovery's AI ecosystem.\n\nAreas of responsibility may include but are not limited to:\n\nAI Platform Engineering and Production Support\n\n• Support the deployment, operation, and maintenance of AI and machine learning solutions across the DS Lab portfolio.\n\n• Contribute to the development of reusable engineering components, deployment frameworks, and operational tooling.\n\n• Assist with troubleshooting production issues, deployment failures, and platform-related incidents.\n\n• Support platform reliability by monitoring system health and escalating issues \n\n• Participate in implementation activities across cloud-native environments.\n\n• Contribute to technical documentation, engineering runbooks, and operational procedures.\n\nGenerative AI and AI Application Development\n\n• Support the implementation of Generative AI, Agentic AI, and conversational AI solutions under the guidance of senior engineers.\n\n• Assist in integrating LLM services, retrieval systems, APIs, and AI applications into broader product ecosystems.\n\n• Contribute to prompt management, testing activities, evaluation workflows, and release processes.\n\n• Help implement monitoring and logging capabilities for AI-powered applications.\n\n• Participate in the development of internal tools and services that support AI product delivery.\n\nObservability and Operational Excellence\n\n• Assist with monitoring AI systems and production services using approved observability tools.\n\n• Contribute to dashboard development, alert implementation, logging standards, and monitoring configurations.\n\n• Help investigate operational issues through log analysis, metrics review, and incident troubleshooting.\n\n• Participate in root cause analysis activities and documentation of lessons learned.\n\n• Support operational readiness activities and production support processes.\n\n• Contribute to maintaining service reliability, availability, and operational performance.\n\nEngineering Standards and Quality Practices\n\n• Follow established engineering standards, coding guidelines, deployment processes, and operational controls.\n\n• Participate in code reviews and technical knowledge-sharing activities.\n\n• Contribute to test automation and software quality initiatives.\n\n• Maintain clear technical documentation and implementation records.\n\n• Apply software engineering best practices under guidance from senior team members.\n\n• Continuously improve technical skills through learning, experimentation, and practical experience.\n\nTechnical Skills\n\nRequired\n\nProficiency in Python for data analysis, and machine
