Company Description

Sequoia-backed healthcare AI startup redefining family caregiving

Job Description

Lead mobile development for an AI-powered platform supporting 50 million family caregivers. As the first dedicated mobile specialist, you will architect and build intuitive iOS and Android applications that function reliably in real-world conditions, including low-connectivity environments. You will bridge the gap between complex care systems and non-technical users.

Location

San Francisco, USA

Why this role is remarkable

  • Join a mission-driven team backed by Sequoia, tackling a massive social problem by providing tools for the invisible backbone of the healthcare system.
  • Massive ownership as the first mobile-focused hire, shaping the architecture, testing frameworks, and release cycles for a high-impact product.
  • High-touch environment where your work directly improves the lives of families, combining cutting-edge AI with deeply human-centric design.

What You Will Do

  • Lead end-to-end mobile development across iOS and Android, taking full ownership from technical design to delivery and performance tuning.
  • Architect offline-first and resilient synchronization patterns to ensure the app remains functional for caregivers in homes with spotty connectivity.
  • Define and implement a comprehensive mobile testing strategy that accounts for device variability, accessibility needs, and real-world usage scenarios.

The ideal candidate

  • 5–7 years of professional software engineering experience with a proven track record of shipping and debugging React Native or native mobile apps.
  • Deep technical expertise in mobile fundamentals, including background execution, local storage, lifecycle management, and modern authentication patterns.
  • Strong product intuition with experience building for non-technical users and a desire to work in a collaborative, fast-paced San Francisco startup environment.

We never post fake jobs

This isn't a trick. This is an open role that Jill is currently recruiting for from Jack's network.

Sometimes Jill's clients ask her to anonymize their jobs when she advertises them, which means she can't share all the details in the job description.

We appreciate this can make them look a bit suspect, but there isn't much we can do about it.

Give Jack a spin! You could land this role. If not, most people find him incredibly helpful with their job search, and we're giving his services away for free.
