Backend Engineer

Overview

What you'll do

• Own exports, media processing, and generation as products.
• Build long-running jobs that recover on their own and report honest progress.
• Manage credits and usage so they are charged fairly and never twice.
• Decide what to build, ship it, and check it worked.
• Talk to users and look at the data.
• Build with AI agents every day, providing the taste and judgment in the loop.

What you'll need

• Experience owning production backend systems while the product kept changing.
• Clear thinking about state, queues, and workers.
• Care about cost as much as speed.
• Strong in TypeScript.
• Comfortable in Python.

Nice to have
