Mobile App Developer – Flutter / React Native

This is a fully remote position, open to applicants in Mexico, +5 more countries.

📋 Description

• Develop and deploy cross-platform applications using Flutter and React Native, from initial specifications to store release.

• Manage the release pipeline, including builds, signing, TestFlight, Play Console submissions, and staged rollouts.

• Connect applications to real backends, including authentication flows, REST and GraphQL APIs, offline caching, background synchronization, and push notifications.

• Dive into native code when necessary, utilizing platform channels, native modules, and bridging with Swift and Kotlin.

• Utilize coding agents to assist with the majority of the coding, followed by a thorough review of the generated code before merging.

• Conduct testing on real devices, monitor crash reports, and address any issues uncovered during testing.

• Integrate applications with Supabase and Firebase, managing authentication, access rules, offline caching, push notifications, and server routes with third-party suppliers.

• Maintain performance standards, focusing on cold start times, frame rates, bundle sizes, and battery consumption.

• Collaborate directly with product owners and designers without any intermediary communication.

⛳️ Requirements

• Over 3 years of extensive mobile development experience, with at least 5 applications successfully released to app stores. Be prepared to discuss any of these applications and defend their architecture.

• A practice of agentic development that emphasizes consistent output and a clear understanding of past limitations.

• Ability to review the output generated by agents, identifying nearly correct authentication flows, unindexed queries, and state persistence issues during hot and cold reloads. Shipping unreviewed output is not acceptable.

• Strong foundational knowledge in software architecture, relational data modeling, app lifecycle and backgrounding, permission models, and OS fragmentation.

• Comprehensive understanding of APIs from end to end, including REST and GraphQL, authentication and token refresh, pagination, retries, timeouts, webhooks, and versioning. Experience integrating third-party APIs even with inadequate documentation is essential.

• Familiarity with store submission processes and policies, including provisioning, signing, package IDs, privacy declarations, and review guidelines. You should have experience addressing and overcoming app rejections.

• Knowledge of platform conventions, including Apple's Human Interface Guidelines and Material Design, ensuring that specifications account for user experience elements such as left-edge swiping, minimum tap targets, confirmation for destructive actions, and existence of loading states.

• Ownership of security practices, understanding that anything compiled into an app is accessible. Experience moving supplier calls server-side to enhance security and establishing correct access rules within Supabase or Firebase is required.

• Proactive identification of potential failure modes before quality assurance, including denied permissions, oversized text on small screens, and stalled uploads. Avoid returning empty lists during network errors to maintain a functional user interface.

🏝️ Benefits

• Engage with products that target both US and global markets, rather than internal tools that won't see external use.

• Experience rapid scaling, with some of our products moving from launch to hundreds of thousands of users within weeks.

• Opportunity to contribute to the next potential unicorn. We collaborate with founders early in the process, so the app you design this quarter may be the one securing Series A funding next year.

• Enjoy a fully remote and asynchronous work environment, allowing you to work where and when you’re most productive.

• Experience genuine autonomy regarding agent setup, architecture, and workflow, as we do not impose rigid processes.

• Access to a tooling budget for model APIs, agent subscriptions, and other resources that enhance your productivity.

• Work on a diverse range of products across various client projects rather than being confined to a single codebase for multiple years.
