- Take part in on-call rotation approximately 2 days per month. You will be responsible for building APIs used by external parties, which come with an uptime requirement.

- 4+ years experience as a Software Engineer.
- Experience with operating and maintaining server-side software in production.
- Experience with Python (most of our rewards data automation is written in Python)
