Senior Mobile Engineer - React Native/Expo, Own & Ship

HellaGoodAudio; San Francisco (CA); In loco; USD 140.000 - 190.000; Tempo pieno

Descrizione del lavoro

HellaGoodAudio is seeking a Senior Mobile Engineer to build and own core features for our collectibles trading card app, Rips, on React Native and Expo. You’ll ship to real users handling real value, balancing correctness, latency and polish from day one.

You’ll work end-to-end, from design discussions to launch and iteration, tackle native modules when needed, collaborate with backend engineers on API design, and shape the architecture so future features come online faster.

Competenze

• Strong mobile engineering background with React Native and Expo.
• Ownership of features from design through launch and maintenance.
• Deep platform understanding and ability to debug framework limitations.
• Ability to establish architecture and guardrails for teams.
• Familiarity with leveraging AI as a tool while maintaining understanding.

Mansioni

• Build and own core product features in React Native and Expo, from design discussion through launch and iteration.
• Take the user experience seriously: motion, gesture, transitions, perceived performance, and the small details that separate an app people tolerate from one they use daily.
• Go below the abstraction when needed: native modules, platform APIs, rendering behavior, build configuration.
• Partner with backend engineers on API and data model design, pushing back when a contract degrades the client.
• Own performance and reliability for what you ship: startup time, frame rate under load, crash-free sessions.
• Raise the floor for the team by setting patterns that accelerate future features.
