You will collaborate with cross-functional teams to translate ambiguous business challenges into rigorous technical solutions.

- Design, develop, and implement small-to-medium ML components on top of the employee listening system - such as theme and sentiment extraction, text classification, and aggregated signal generation - with input and guidance from senior scientists, taking ownership of the code in your components.

- Write secure, stable, testable, maintainable, well-reviewed code (at the SDE I bar) to deliver solutions into production that benefit customers and the business.

- Design features and signals responsibly, applying privacy-preserving practices appropriate to sensitive employee data.

- Collaborate with cross-functional partners to understand business context and impact, and help mentor interns.
