Senior Backend Engineer
As a Senior Software Engineer on the Ecosystem Services Team, you’ll build and own back-end systems and the integrations that keep our services running, help maintain and evolve the cloud infrastructure the application runs on, and play an active role in keeping the service reliable and healthy in production. You'll do this while collaborating closely with frontend engineers, product managers, CloudEng, and UX and design partners to deliver reliable features. We are looking for engineers who treat the systems they build as their own: people who are comfortable owning a service end to end, from writing the code to verifying it works as intended in production and monitoring its health.
