You'll work directly on the systems that keep our messaging infrastructure running — and have real ownership over making them better.

You'll own the reliability and performance of our messaging infrastructure across every protocol we support. iMessage certs expiring on hardware, RCS implementation quirks, SMS rate limits, fallback logic when things break — this is your world. The job is to know these systems better than anyone and stay ahead of the problems before they become outages.
