About the Team
Our engineering team has a strong culture of working in an agile, continuously improving, and automation-oriented environment. We recognize the need to always be evolving, to look objectively at where things are getting better or worse, and take action.
We design and implement new machine learning systems to curate, personalize, and recommend content to OpenSesame customers. We currently own models for recommendations, similar content, search, and course enrichment, and will be embarking on exciting new initiatives over the next year. The team is responsible for end-to-end machine learning systems from experimentation, data exploration, and new proof of concepts to data pipelines, CI/CD, and API development.
About the Job
As a Lead Machine Learning Engineer, you will be a core designer and developer of the machine learning infrastructure we use for all our models. This role will be responsible for building reliable data pipelines, experimentation infrastructure, model training and serving infrastructure, serverless API development, and be an active contributor to the development of new models.
You will design systems that let us move quickly and confidently, while minimizing maintenance overhead so we can focus more of our energy on exciting modeling projects. You will be expected to be a growing engineer capable of mentoring others, learning from others, and contributing to the team in every way to keep OpenSesame moving forward.
