Our inclusive environment welcomes skills and experiences from diverse backgrounds and defines who we are.

About the role - What’s your purpose?

This particular role will initially be within a team whose responsibilities include effectiveness and efficiency of our labelling processes and tool, training, monitoring and deployment of systems and models for entity linking, text classification and sentiment analysis, among others, across multiple data types. This team also works closely with the operation teams to ensure systems and models are properly maintained.

This encompasses helping your team discover problems and explore the feasibility and value of potential ML-driven solutions; building prototype solutions and conducting offline and online experiments for validation; collaborating with engineers and product managers on bringing further iterations for those solutions into the products through integration, deployment and scaling. You will be involved in setting the team’s objectives and key results, in monitoring product metrics, and in analysing changes in metrics and user behaviour.
