Job description

Job Description: iOS / Swift Expertise Expectations

UI Complexity (Very Critical)

Experience with complex UI work is critical. This role heavily supports Chat and PPA experiences, where animations, transitions, motion, and custom UI components are core to the user experience.
PPA experience is the single most important requirement, followed closely by Health Center experience. Candidates should have demonstrable experience building interactive, polished, UI-heavy mobile experiences.

AI / PPA / Gen-AI Involvement

The role is primarily focused on consuming APIs, not building AI or Gen-AI models. The engineer will integrate AI-powered and PPA services into iOS user experiences, ensuring smooth UI, correct data handling, and strong performance. Experience working with API-driven personalization or AI-assisted features is ideal, but deep AI expertise is not required.

What We’re Screening For

• Proven ownership of UI-heavy features
• Ability to reason through problems, not just execute tickets
• Comfort working across PPA, Chat, and Help Center surfaces
• Clear communication and collaboration with Product and Design

What We’re Not Optimizing For

• Backend or AI model development
• Candidates focused mainly on web, hybrid frameworks, or backend work
• Candidates with a fundamental level of front end development

Role Expectations & Skill Requirements

• Platform: iOS
• Language: Swift
• Must be a pure iOS developer capable of building features end-to-end
• Strong problem-solving ability prioritized over resume pedigree
• Emphasis on intellectual rigor and engineering depth (“who’s smarter,” not just strongest background)

UI / UX Complexity

• Experience with complex UI is critical, particularly for:
• Animations
• Transitions
• PPA experience: Extremely high priority
• Health Center experience: Extremely high priority

AI / PPA / Gen-AI Involvement

• Primary responsibility:
• Consuming APIs
• Building or training AI/Gen-AI models
• Focus: Integrating AI-powered services into user-facing iOS experiences
