Event discovery, ticketing, news and long-form editorial, artist profiles, original films, and a weekly mix series two decades deep. Around 7 million people use the web platform every month, with a wider audience across our apps and other channels. Underneath the platform sits a network of contributors and city managers across dozens of cities, which is how we stay connected to the scenes we cover rather than reporting on them from a distance. RA is 25 years old, independent, B.Corp certified and intent on being indispensable to the artists, promoters and audiences who make this culture. The role You'll build features for the RA Guide iOS app from design to release, with support from the Apps lead and room to grow towards senior. RA Guide is RA's app for browsing events and buying tickets, native on iOS and Android and used by thousands of people every day. We also make RA Scan, a cross-platform app promoters use to scan tickets at the door. You'll join the Apps team: the Apps lead (who also builds on iOS), an Android developer and a product manager, working closely with design and the web teams who build the APIs the app uses. We release weekly. Native releases can't be rolled back once they're out, so we care about getting each one right: tests, careful review, and watching what happens after release. Responsibilities * Build new features and improvements from designs and specs, and see them through to the App Store * Write testable Swift, with unit tests and UI tests alongside it * Fix bugs and crashes, using our monitoring to find what's hurting users most * Take part in code review, giving and getting feedback * Work with the product manager and designer to turn user needs into a polished experience * Use AI tools where they help, and check what they produce, * SwiftUI * GraphQL * UI testing with XCUITest * A/B testing or phased rollouts * Android or cross-platform experience * An interest in electronic music and the scenes RA serves What we offer you * Generous annual leave policies aimed at promoting work-life balance. * Matched pension, or 401k for US staff. * Comprehensive staff wellbeing initiatives, featuring regular activities and workplace programmes to support mental and physical health. This includes discounted ClassPass memberships and custom-fitted earplugs. * Company-led social events, team lunches, and discounts on merch. * Paid annual volunteering allowance, encouraging contributions to community projects and charities you care about. * A transparent internal company culture committed to diversity, equity, and inclusion (see: https://ra.co/about/diversity). * Active involvement in community projects within the electronic music community (see: https://ra.co/about/community). ## Related Videos - [SwiftUI In Production](https://www.wearedevelopers.com/videos/134-swiftui-in-production) - [From Zero to Mobile Developer in 45 Minutes With SwiftUI](https://www.wearedevelopers.com/videos/183-from-zero-to-mobile-developer-in-45-minutes-with-swiftui) - [Putting the Graph In GraphQL With The Neo4j GraphQL Library](https://www.wearedevelopers.com/videos/257-putting-the-graph-in-graphql-with-the-neo4j-graphql-library) - [Harnessing Apple Intelligence: Live Coding with Swift for iOS](https://www.wearedevelopers.com/videos/1515-harnessing-apple-intelligence-live-coding-with-swift-for-ios) - [Unsolved mysteries between Usability and Accessibility in iOS](https://www.wearedevelopers.com/videos/737-unsolved-mysteries-between-usability-and-accessibility-in-ios) - [Xcode development redefAIned](https://www.wearedevelopers.com/videos/100195-xcode-development-redefained) ## Related Articles - [A Guide to Choosing the Right Tools for App Developers](https://www.wearedevelopers.com/magazine/391-a-guide-to-choosing-the-right-tools-for-app-developers) - [Cross Platform Mobile Development Frameworks to Use in 2025](https://www.wearedevelopers.com/magazine/404-cross-platform-mobile-development-frameworks-to-use-in-2025) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 118 - not a total recall](https://www.wearedevelopers.com/magazine/452-dev-digest-118-not-a-total-recall) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift)
