This engineer will own complex technical initiatives end-to-end, contribute to the architecture of Apple applications, and partner with technical leadership to establish engineering best practices. AI-assisted development is a core expectation for this role.

This role sits at the intersection of deep Apple platform engineering and AI-native development — daily use of AI agents and coding tools (Cursor, Claude Code, Copilot), hands-on collaboration with ML and data science teams, and practical experience shipping LLM- or ML-powered features such as recommendations, search, personalization, and conversational interfaces.

Key Responsibilities:

• Contribute to architectural decisions, frameworks, and tooling for iOS and tvOS applications.
• Design, develop, test, debug, and deploy native Apple platform applications.
• Drive application performance, reliability, accessibility, and scalability.
• Utilize AI coding assistants such as Cursor, Claude Code, GitHub Copilot, or equivalent as part of daily development workflows.
• Collaborate on ML- and LLM-driven product features including recommendations, search, ranking, and content understanding.
• Mentor engineers through code reviews, design reviews, and technical guidance.
• Partner with Product, Design, Data, Backend, and Client Engineering teams to deliver features.
• Manage multiple projects simultaneously and proactively identify risks and dependencies.

Required Skills:

• Expert-level Swift development experience.
• Deep knowledge of iOS, tvOS, and Xcode.
• Strong understanding of memory management, concurrency, animations, and performance optimization.
• Experience integrating RESTful APIs and backend services.
• Strong architectural and problem-solving skills.
• Experience with A/B testing, feature flagging, and client-side experimentation frameworks.
• Experience integrating advertising technologies into Apple applications.
• Excellent communication, collaboration, and mentoring abilities.

AI Literacy:

• Daily hands-on use of AI coding assistants.
• Experience with prompt engineering and evaluating AI-generated code.
• Working knowledge of LLMs, embeddings, retrieval systems, and AI application design considerations.
• Experience building or prototyping AI-powered product features.
• Understanding of responsible AI practices, including privacy, attribution, and review processes.

Basic Qualifications:

• 7+ years of Apple platform development experience.
• Significant contribution to at least one publicly released iPhone application.
• Demonstrated use of AI coding tools in day-to-day engineering work.
• Experience working in Agile development environments.

Preferred Qualifications:

• Bachelor's degree in Computer Science or a related technical field, or equivalent experience.
• Experience integrating video and rich media into mobile applications.
• Experience building personalized, data-driven, or server-driven user experiences.
• Experience shipping ML- or LLM-powered mobile features.
• Experience in entertainment, media, sports, gaming, or news industries.

Bonus Skills:

• Continuous integration and automated testing.
• Streaming video technologies and DRM.
• Localization tools and practices.
• Swift Package Manager.
• Experience evaluating AI model quality, latency, and cost trade-offs.
