About The Role
We are looking for a Principal Machine Learning Engineer to shape the next generation of our data and machine‑learning capabilities. The focus will be on data quality, enrichment and the intelligent linking of products and information, defining architectural strategy, leading transformative initiatives and working at scale on platforms infused with machine learning and semantic intelligence to unlock deep insights from complex data.
Responsibilities
* Lead the architecture and evolution of scalable, high‑performance data pipelines and ML systems, focusing on data ingestion, transformation, quality checks, and enrichment.
* Provide technical leadership and mentorship to a cross‑functional team of ML Engineers, Data Scientists and Infrastructure Engineers, ensuring alignment with architectural standards and driving a culture of high quality and operational excellence.
* Drive cross‑functional initiatives to integrate modern Machine Learning and AI technologies (including semantic understanding, natural language processing and potentially large language models) to automate data quality, link canonical products and create intelligent data enrichment solutions.
* Define strategies to enhance the performance, reliability and observability of data and ML services, ensuring robust, high‑quality data outputs.
* Design and implement frameworks for evaluating data quality and the effectiveness of ML models through both offline metrics and online validation.
* Champion engineering best practices and mentor engineers across teams, raising the bar for code quality, data governance and ML system design.
* Shape long‑term technical direction by staying ahead of trends in AI, ML, data engineering and distributed systems and bringing these innovations into production within the Knowledge domain.
Requirements
* Extensive experience designing and leading the development of large‑scale distributed data and/or ML backend systems.
* Hands‑on experience with ETL pipeline design and optimisation for complex data sets is a strong advantage.
* Deep familiarity with technologies such as Apache Beam, Pub/Sub, Redis and other large‑scale data processing frameworks.
* Expertise in backend development with Python and Scala; knowledge of Node.js or Golang is a plus.
* Proficient with both SQL and NoSQL databases, and experience with data warehousing solutions.
* Demonstrated experience building robust APIs (REST, GraphQL) and operating in modern cloud environments (GCP preferred), using Kubernetes, Docker, CI/CD and observability tools.
* Proven ability to lead and influence engineering direction across teams and functions, particularly in a data‑centric and ML‑driven environment.
