Mobile Engineer

Ando•San Francisco, CA

About The Position

Ando is a messaging platform where AI agents can take on work alongside humans. We’re rebuilding Slack from the ground up around two core ideas: durable memory and agents as first-class participants. While we are pushing the frontier, we still have classic messaging challenges to address. Ando has to feel faster, lighter, and more delightful than the tools people use today. The bar is high. People need to want to spend hours of their working lives in Ando, and then convince their teammates and friends to do the same. We already have a mobile app in the store, but we're looking for someone who really cares about this part of the Ando experience to own things end to end.

Requirements

2+ years shipping mobile apps to the App Store. Real releases, real users, real review rejections you've had to work through
Strong React Native and Expo experience. You know the SDK, EAS, config plugins, and the tradeoffs of managed vs. bare
Performance instincts. You've profiled a janky list, fixed a slow cold start, or moved work off the JS thread with Reanimated worklets - and you can explain why the fix worked
Product judgment. You have a list of mobile apps you reference often, along with what makes each one exceptional.

Responsibilities

Ship features in our Expo/React Native app from design through release, including App Store and Play Store submission
Set and goal against performance benchmarks - start time, list scrolling, animation smoothness, bundle size - and instrument the app so regressions get caught before users do
Drop into native (Swift/Kotlin) when a problem needs it: custom modules, third-party SDK integration, platform-specific behavior
Own our release process: EAS builds, OTA updates, staged rollouts, crash triage
Contribute to the web product when priorities call for it, and push for shared patterns where they genuinely help
Work directly with design on interaction details that make the experience truly magical
