As part of our team, you’ll play a critical role in improving customer experiences by scaling our services and contributing to our culture of innovation and continuous improvement. You’ll work closely with our backend, infrastructure, and application engineers, as well as our outstanding customer support team to deliver an unmatched customer experience. HOW YOU’LL HELP US WIN Contribute to our collection of highly-scalable services (some stateless, some stateful).

Experience with Cgo is a bonus. - Familiarity with our tech stack (or equivalents): GCP/GKE, Linux, Docker, Ruby/Rails, Redis, ffmpeg - Experience in a SaaS or PaaS environment at our scale (currently 100s of millions of async jobs per week).

We’re established enough to ship instead of fighting fires and early enough that your work will have a real impact. - Startup experience. You’ll work closely with our CEO, a 2X Founder/CEO with a background in computer science and product design. - We embrace being fully remote. We schedule meetings sparingly and instead heavily use async comms (Slack, Notion, Loom) ABOUT THE INTERVIEW - No live coding. We have no idea who thought writing code on whiteboards was a good idea but we hate it. We’re much more interested in what you’ve done and learned. - You’ll meet the entire team. We think it’s important that you get to meet everyone you’ll be working with. - No bullshit. Ask us anything you like. We’ve never understood why companies pretend they’re something that they’re not in the hiring process - you’re going to find out eventually so we’d rather you know who we are up front so we can both make sure this is a good fit for all involved. - Quick turnaround time. We know you have lots of options so we move fast usually in less than a week from start to finish.
