Job summary

TuneCore Engineering is seeking a senior Fullstack React Native Developer to craft the next generation mobile experience. You will own mobile architecture, mentor engineers, and stay hands-on in code.

You’ll design cross‑platform mobile apps in React Native, build Rails API endpoints, and collaborate with product/design/backend teams to ship high‑quality features while optimizing performance and release workflows.

Qualifications

• 6+ years of experience writing production code, including 3+ years building and shipping mobile applications.
• Demonstrated fluency with Ruby on Rails in production — API‑only Rails services
• Familiarity with state management approaches (React Query and Context API)
• Experience with Git, CI/CD pipelines, and mobile release workflows
• Understanding of mobile UI/UX principles and platform guidelines (Apple HIG, Material Design)
• Experience with REST APIs and async data handling; GraphQL a plus
• Experience with native iOS or Android a plus, but not required
• Bachelor’s or Master’s degree in Computer Science, or equivalent practical experience

Responsibilities

• Design, build, and maintain cross‑platform mobile applications using React Native for iOS and Android from a single codebase
• Build and maintain the Rails API endpoints that power the mobile app — request/response contracts, background jobs, and data models the client depends on
• Work closely with product, design, and backend engineers to translate designs and wireframes into high‑quality, reusable code across the full stack
• Integrate RESTful APIs and third‑party SDKs; optimize app performance, responsiveness, and stability
• Write unit and integration tests, and help shape our mobile testing strategy as we build out React Native end‑to‑end coverage
• Debug and resolve platform‑specific issues, including native modules and bridging
• Manage app store submissions and release processes for both the App Store and Google Play
• Stay current with the React Native ecosystem and mobile best practices, and bring relevant updates back to the team
• Uphold TuneCore’s core mission, vision, and values in the code you ship and the decisions you make
• Provide technical leadership on mobile architecture decisions, balancing durability and scalability against delivery speed
• Set and evolve coding standards and best practices for the mobile codebase
• Give effective, constructive code review feedback to other engineers
• Mentor and guide engineers on the team in both technical growth and career development
• Research and recommend new tools and technologies where they’d meaningfully improve the team’s output
