Responsibilities (What he/she will do after join UI)
- Design and build the core synchronization and metadata handling logic for UniFi Drive on macOS, enabling reliable and intuitive access to files across local and cloud environments.
- Build platform-integrated file experiences by working with macOS system behaviors and APIs, with a focus on correctness, performance, and meeting native user expectations.
- Tackle non-trivial system problems that arise in real-world usage, such as handling change, coordination, and edge cases across devices and environments.
- Collaborate closely with backend and infrastructure teams to align on data models, APIs, and end-to-end reliability.
- Work with product and design partners to translate user workflows into robust technical solutions, balancing system constraints with user experience.
- Continuously improve performance, stability, and maintainability through measurement, profiling, and iterative refinement.
Minimum Qualifications (MUST-haves)
- 3+ years of professional software development experience, or equivalent experience, building and shipping production systems.
- Hands-on development experience on Apple platforms (macOS and/or iOS), with familiarity with the Apple development ecosystem and real-world production workflows.
- Strong computer science fundamentals, with the ability to reason clearly about complex system behavior and trade-offs.
- Ability to build clear mental models, decompose ambiguous problems, and make thoughtful engineering decisions rather than relying solely on predefined patterns or recipes.
- Solid programming skills in Swift or Objective-C, with attention to correctness, readability, and long-term maintainability.
- Proficient with Git and modern development workflows, including code review, incremental delivery, and collaboration within a team.
- Comfortable navigating uncertainty, asking good questions, and working effectively in a fast-evolving platform environment.
Preferred Qualifications (Nice-to-haves / Plus)
