Job Description

We are seeking a Senior React Native Mobile Developer to lead end to end mobile app development for iOS and Android in a hybrid environment. This role requires deep expertise in React Native, mobile architecture, and performance optimization, with a strong ability to collaborate with client stakeholders, architects, and product owners to deliver secure, scalable, and high performance mobile solutions. You will also mentor junior developers, drive CI/CD and app store deployment, and incorporate emerging technologies like LLMs (Large Language Models) to accelerate development.

Key Responsibilities

• Lead end to end mobile application development using React Native for iOS and Android platforms, from concept to production.
• Participate in and influence mobile architecture, design decisions, and technical roadmap discussions.
• Guide and mentor mobile developers, conduct code reviews, and enforce best practices, standards, and performance focused development.
• Collaborate closely with onsite client stakeholders, architects, and product owners to understand business needs and translate them into technical solutions.
• Translate business requirements into scalable, high performance mobile apps that meet UX, performance, and security expectations.
• Drive performance optimization, app stability, memory management, and crash reduction across mobile platforms.
• Ensure strict adherence to security, compliance, and enterprise mobility standards (e.g., encryption, secure storage, device management).
• Integrate mobile apps with REST APIs, GraphQL, backend services, and third party SDKs.
• Hands on experience with WebSockets, RTC (Real Time Communication), and LaunchDarkly (feature flagging/feature toggles).
• Manage CI/CD pipelines, build processes, and app store deployments (Apple App Store and Google Play Store).
• Support troubleshooting, production issues, and root cause analysis for mobile apps.
• Participate in sprint planning, estimations, and technical risk management within Agile/Scrum processes.
• Contribute to POCs, technical feasibility studies, and innovation initiatives, including the use of Large Language Models (LLMs) to accelerate development.
  • Use LLMs to craft effective prompts, review AI generated code, and ensure correctness, security, performance, and adherence to coding standards.

Technical Skills

• Strong, hands on experience with React Native, JavaScript, and TypeScript.
• Solid understanding of native iOS and Android platforms, including platform specific considerations and limitations.
• Experience with mobile state management frameworks such as Redux, Context API, MobX, or Redux Toolkit.
• Knowledge of mobile UI/UX guidelines, accessibility (WCAG), and responsive design for iOS and Android.
• Experience with app security, encryption, and secure storage (e.g., keychain, key vault, secure storage libraries).
• Familiarity with cloud platforms such as Azure/AWS and Firebase for backend and analytics integration.
• Experience with analytics tools (e.g., Google Analytics, Mixpanel, Amplitude) for mobile apps.
• Exposure to single sign on (SSO), OAuth, SAML, and enterprise authentication mechanisms.
• Experience using LLMs (Large Language Models) in the development workflow, including prompt engineering, code review, and security/performance optimization for AI generated code.
• Experience with WebSockets, real time communication (RTC), and LaunchDarkly for feature toggling and experimentation.

Non Technical Skills

• Strong onsite communication and stakeholder management skills, with the ability to present technical concepts clearly to non technical audiences.
• Ability to drive discussions, resolve technical conflicts, and influence technical decisions.
• Experience working in Agile/Scrum environments, including sprint planning, backlog grooming, estimations, and retrospectives.
• Good documentation and presentation skills, including maintaining architecture diagrams, technical specs, and user guides.
• Ability to mentor junior developers and lead cross functional mobile teams.
