Sr. Principal Engineer - FoundationDB

Apple is home to some of the most complex and consequential infrastructure in the world. At the center of iClouds platform is FoundationDB, a planet-scale database system powering tens of billions of databases and some of Apples 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. 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 dont 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.

You wont just be close to these problems. You will shape the technical vision and approach for solving them, influence the engineers tackling them day to day, and help grow the team that turns that vision into reality.Define and drive the long-term technical vision and architectural direction for FoundationDB, setting the bar for engineering excellence across trade-offs, problem-solving approaches, and architectural integrity at scale. Provide deep technical guidance on the most complex, highest-impact challenges the team faces, proactively surfacing risks, gaps, and scalability constraints before they become critical. Partner closely with engineering leadership and cross-functional teams to align technical direction with business and platform priorities. Elevate the broader organization through thought leadership and mentorship, while playing an active role in defining the technical hiring bar and developing the next generation of engineers. Lead the rethinking of the transaction layer and scalability architecture from first principles, pressure-testing every assumption the current system makes. Guide team in future initiatives pertaining to building the next-generation CDC pipeline, log storage, and build tiered storage.15+ years of experience designing, implementing, and operating highly scalable distributed systems. Deep expertise in planet-scale database systems, with hands-on experience in systems such as Spanner, DynamoDB, CockroachDB, or comparable technology. Proven ability to define and communicate long-term technical strategy across large, complex engineering organizations. Strong cross-functional partnership skills, with experience working closely with platform, infrastructure, and product engineering teams. Exceptional written and verbal communication skills -- able to articulate complex technical concepts clearly to both technical and non-technical audiences. A strong sense of ownership and a track record of driving outcomes in ambiguous, high-stakes environments. Bachelors degree in Computer Science, Engineering, or a related field, or equivalent experience.Experience with modern data storage systems. Knowledge of security & privacy.
