Sr. Principal Engineer - FoundationDB

Summary

Apple is home to some of the most complex and consequential infrastructure in the world. At the center of iCloud's platform is FoundationDB, a planet-scale database system powering tens of billions of databases and some of Apple's most critical services.

We are looking for a Principal Engineer to join this team and serve as its technical north star: defining architectural direction, shaping the hardest problems in distributed databases, and helping grow the team that brings that vision to life.

Description

FoundationDB is the metadata layer behind iCloud Storage, operating at a scale that puts it in rare company globally. And because this technology is open source, the architectural decisions made here don't stay inside Apple, they ripple across the broader technology ecosystem, powering some of the most technically demanding systems in the world.

This is a pivotal moment for the team. We are in an active growth phase and looking for a Principal Engineer who will serve as the technical north star through that expansion. The hardest and most interesting problems in distributed databases are ahead of us, and you will define how we approach them.
