Senior Machine Learning Engineer, Learner Modeling

We're looking for a Senior Machine Learning Engineer to build and own the learner models behind our mastery and progression capabilities. You'll design the models, build the pipelines that train and score them, and own their quality once they're running in production.

You'll partner with our learning scientists on what these models should measure, and with our infrastructure team on deployment and operations.

• Design and build learner models, including knowledge tracing and longitudinal approaches, that power mastery and progression features surfaced to learners and educators
• Shape the data foundation for learner modeling: define which signals matter, and build the datasets your models depend on
• Translate mastery and progression definitions into model targets and evaluation criteria, working with learning scientists and product partners
