For day-to-day feature work, our engineers are organized into smaller cross-functional feature squads or teams. Our squads have a great deal of autonomy and are responsible for the development and architecture of their features. Squads take full ownership of their code and handle everything from concepting, design and implementation to release, maintenance and bug fixes. This is a remote US role with a preference for candidates based in the US-Pacific timezone. We have offices in San Francisco and San Diego for those who prefer hybrid or office settings. We also have employee hubs in New York City, Boston, Los Angeles, Seattle, and more. We are seeking a highly motivated Senior Backend Engineer to join one of our growing teams.
