Senior Software Developer - Mobile Technologies (Miami/Hybrid)
About The Role
Boats Group runs some of the most heavily trafficked marketplaces in the boating world, and React Native is a first-class platform here—not an experiment or a wrapper. Our mobile apps power discovery, messaging, lead flow, and transactions for millions of users and thousands of dealers globally. As a Senior Mobile Engineer (React Native), you’ll work on a long-lived React Native codebase where architecture, performance, and developer experience actually matter. You’ll help shape how we structure shared components, manage state, handle offline and flaky-network scenarios, and integrate cleanly with native iOS and Android when it counts. This is a role for engineers who enjoy going deep: profiling performance, eliminating re-render bottlenecks, designing scalable patterns, and making pragmatic tradeoffs between shared and platform-specific code. You’ll collaborate closely with backend and product partners, but you’ll also have real ownership over mobile technical direction—what we standardize, what we refactor, and what we never let regress. If you’re excited by React Native at scale, care about clean abstractions and production-grade quality, and want your work in the hands of a massive, real user base, Boats Group gives you both the challenge and the leverage.
What You’ll Do
- Build and ship production-grade React Native applications used by a large, real-world audience
- Drive adoption of modern React Native capabilities and performance improvements
- Own features from idea architecture implementation
- App Store / Play Store
- Architect reusable components and modular application structure
- Collaborate closely with product, design, backend, and architecture partners
- Help define mobile engineering standards, patterns, and long-term technical direction
- Mentor other engineers through thoughtful code reviews and technical leadership
- Translate business goals into elegant, scalable mobile solutions
What You Must Have
- BS in Computer Science/related field of study or equivalent experience developing and maintaining complex consumer mobile applications in a dynamic and fast-paced environment
- Experience in advanced implementations using React Native preferably experience with React Native New Architecture and frameworks like TanStack Query.
- Strong debugging, profiling, and performance optimization skills
- Solid experience with Redux or similar state management tools
- Strong proficiency in TypeScript
- A solid understanding of continuous integration, continuous deployment with Github Actions
- Experience publishing React Native apps to their respective stores (and working through their respective approval processes)
- An understanding of web services (RESTful and RPC based), JSON payloads with stateless restful polyglot services
- An understanding of agile software development practices
What You Should Have
- Experience publishing apps to App Store and Google Play
- Familiarity with native Android (Kotlin/Java) and/or iOS (Swift)
- Experience with automated testing frameworks (Jest, Appium)
- Experience working with React Native New Architecture (Fabric, TurboModules, JSI)
- Nice to have Experience with TanStack Query (React Query) for server-state management
- Experience with GraphQL
- Experience building cloud-backed applications on AWS
- Search technologies like Elasticsearch/OpenSearch
- Queueing technologies
- A strong opinion on mobile UX—and the ability to back it up with execution
What You'll Receive
- Hybrid Work Flexibility: Embrace a balanced work model with remote work on Mondays and Fridays and in-office collaboration from Tuesday to Thursday.
- Generous Time Off: With a strong focus on work/life balance, we offer all employees paid time off starting on day one, multiple paid holidays throughout the year, your birthday off, and a winter break at the end of the year.
- Volunteering Time: Participate in our volunteer program with 4 paid days annually to contribute to your community.
- Modern Office Perks: Our vibrant Miami office features cutting-edge amenities, such as an electric sit/stand desk, dual monitors, a gym, and a variety of snacks and beverages.
- Comprehensive Benefits Package: Enjoy top-tier Medical, Dental, Vision, and Life insurance, along with a 401(k) plan featuring a 4% match.
- Commuter Benefits: Park conveniently in our building’s garage at no charge to you. For train commuters, we subsidize most, if not all, of your monthly pass expenses.
- Professional Development: Take advantage of online training, live courses, and additional funds for courses, seminars, and certifications to enhance your skills.
- Team-Centric Atmosphere: Be part of a close-knit team that prioritizes relationship-building and personal connections.
