**Technologies we use:**

- Python
- Typescript, React, Redux
- numpy, pandas, sklearn
- Django, sqlalchemy
- Aurora, Cassandra, Kafka, Redis, Pulsar

**How you will make a difference:**

- Build a platform that enables robust experimentation and drives learning for customers
- Fully shepherd features from conception through rigorous experimentation to deployment
- Enable testing at scale. > 60k unique campaigns are tested via our platform each month
- Provide features that enable rigorous analysis without the need for a statistical background

**Who You Are:**

- Desire to build clean software and a drive to push others to do the same
- Interested in data science while primarily focusing on difficult engineering problems
- Experience building full-stack, or large portions of, full-stack applications
