Job description

The Apple Postgres team develops and operates a highly reliable, cloud relational database service that serves all of Apple. As a PostgreSQL committer joining at this level, you will act as an established technical authority and thought leader for PostgreSQL internals and features - anticipating and framing systemic challenges, shaping technical direction across multiple teams, and ensuring consistency and a high-quality bar in everything from query execution, storage, replication, high-availability, scaling and administration to new feature development and every other aspect of the database. You will operate at the intersection of Apple and the upstream community, driving an upstream-first strategy so that Apple's needs are met in community PostgreSQL rather than through divergent implementations. You will advise engineering leaders and key stakeholders to align technical execution with business priorities, and serve as the key resource whose judgment shapes critical decisions for the Postgres domain. Success in this role is built on deep PostgreSQL expertise, together with a strong command of the systems the database runs on and the discipline to keep it fast and reliable at scale: - PostgreSQL internals — first-hand, contribution-level knowledge of the engine, whether in the query planner and executor, storage and access methods, WAL and recovery, replication, MVCC and concurrency, or the extension and API surface. - The systems the engine runs on — the operating-system principles (process scheduling, memory management, disk and network I/O) and server-class hardware (storage devices and controllers, network interfaces) that determine how PostgreSQL performs and stays durable. - Behavior at scale — how distributed, high-throughput systems handle replication, failure detection, load balancing, and request pipelining, and the consistency, isolation, and availability trade-offs they must make. - Engineering for performance and correctness — profiling, benchmarking, and advanced testing methodologies, together with fluency in the debugging tools needed to diagnose issues in development and production. The role also requires excellent communication and the ability to partner closely with our Database Engineering and SRE teams, a high degree of customer focus when engaging with internal customers, and the ability to explain highly complex technical material clearly and concisely to leaders across the organization. The ability to work effectively with colleagues based in other locations is essential. Current or former committer to the PostgreSQL open source project. Demonstrated, sustained record of contributing features to PostgreSQL that have been well received upstream. BS in Computer Science/related fields with 10+ years of relevant experience. High level of proficiency in C (and, where relevant, C++ or Rust). Advanced understanding of data structures and algorithms in storage and indexing. Deep knowledge of the internals of PostgreSQL. Demonstrated technical leadership and the ability to set technical direction across teams. MS or PhD in Computer Science/related fields (MS with 8+ years or PhD with 5+ years of relevant experience). Authorship of major PostgreSQL features, or sustained maintainership of a significant subsystem of the database. History of speaking at PostgreSQL developer conferences, and of mentoring other contributors. Knowledge of Linux Kernel development, and performance optimizations
