We have multiple opportunities available across a range of different areas. In this role, you’ll build and maintain the backend systems that power our product experience, develop APIs that support our mobile and web applications, and deliver robust, maintainable code, all within a fast-paced, daily deployment environment. Our backend is primarily built in Python and runs on AWS. We use technologies including Flask, Pytest, Mypy, Docker, PostgreSQL, SQS, S3, and Terraform.

Shape technical direction — Contribute to architectural decisions and broader technical strategy. Collaborate across teams and partners — Work closely with engineers, product teams, and external vendors to integrate third-party systems seamlessly. Ship with confidence and speed — Deliver features and improvements in a continuous deployment environment.
