About The Position

Join the Final Cut Pro engineering team — Apple's flagship professional video
editing suite used by major Hollywood studios and millions of creators worldwide
— and help shape the next generation of data infrastructure powering
professional creative workflows. As a Senior Applications Engineer specializing
in Data Infrastructure, you will bring deep expertise in database internals,
on-device data systems, and high-performance computing to a team building the
persistence and data layer foundations of Final Cut Pro — where managing complex
object graphs, transactional integrity under real-time demands, and long-term
architectural evolution are the everyday reality. You will contribute strong
systems-level thinking and architectural depth while helping expand the team's
collective knowledge in modern data patterns — including distributed systems
concepts and microservices design — and how they can be thoughtfully applied to
a demanding desktop application environment. This is a hands-on engineering role
for someone who thrives at the intersection of systems engineering and data
architecture — excited to bring expertise from backend, infrastructure, or
distributed systems domains into a performance-critical creative application
where data integrity and responsiveness are non-negotiable. You will work with a
high degree of autonomy alongside engineers who care deeply about craft and
correctness.

DESCRIPTION

Design and evolve Final Cut Pro's persistence layer, including schema design,
query optimization, and data storage for multi-gigabyte project files requiring
real-time responsiveness. Design and implement scalable data models that support
complex media workflows, drawing on deep knowledge of database internals,
indexing strategies, and I/O optimization. Participate in architectural
discussions, code reviews, and engineering excellence initiatives — bringing
distributed systems and modern database perspectives to broaden the team's
technical toolkit.

Requirements

• 7+ years of experience in applications, platform, or infrastructure engineering with a strong focus on data systems design and implementation.
• Deep expertise in database internals — query planning, indexing, transaction management, and schema migration strategies.
• Proficiency in Swift, C++, or Rust — with a strong emphasis on memory management, concurrency, and performance optimization.
• BS or MS in Computer Science, Engineering, or equivalent practical experience, with demonstrated depth in systems programming, distributed computing, or database engineering.

Nice To Haves

• Hands-on experience with embedded or local database technologies such as SQLite, Realm, LevelDB, or similar — particularly in the context of client-side or on-device data management.
• Familiarity with distributed data patterns — including microservices architecture, CQRS, or CRDTs, and a genuine interest in exploring how these concepts could benefit on-device and desktop application data layers.
• Familiarity with Apple's development ecosystem (macOS, iOS, Xcode) or demonstrated ability to ramp quickly on a new platform environment.
• Experience working in large, complex codebases with incremental modernization goals and long-term architectural vision.
• Exposure to media, graphics, or creative software domains is a plus, but not required — curiosity and enthusiasm for the problem space matters more.
• Knowledge of data migration strategies and performance tuning for I/O-bound systems.

Responsibilities

• Design and evolve Final Cut Pro's persistence layer, including schema design, query optimization, and data storage for multi-gigabyte project files requiring real-time responsiveness.
• Design and implement scalable data models that support complex media workflows, drawing on deep knowledge of database internals, indexing strategies, and I/O optimization.
• Participate in architectural discussions, code reviews, and engineering excellence initiatives — bringing distributed systems and modern database perspectives to broaden the team's technical toolkit.
