• Contribute to web frontend features using React and TypeScript when product priorities require it.

Technical Focus and AI-Assisted Engineering

• Design mobile experiences that maintain functionality and predictability when network connectivity is weak, interrupted, or unavailable.
• Implement local data models, caching mechanisms, migrations, synchronization, retries, and conflict handling using technologies such as SQLite or Realm Database.
• Integrate REST APIs and manage asynchronous data and application state using tools like Redux Toolkit or TanStack Query.
• Debug and optimize application performance across various devices, operating systems, and network conditions.
• Utilize AI coding agents, including Claude Code, Codex, or Cursor, as an integral part of the daily engineering workflow.
• Provide clear context to AI coding agents, segment work into meaningful steps, and direct them effectively across the codebase for tasks such as implementation, testing, debugging, refactoring, maintenance, and technical documentation.

Quality, Testing, and Technical Leadership

• Write and maintain unit, integration, and end-to-end tests using tools such as Jest, React Testing Library, or Detox.
• Assume ownership of technical decisions regarding mobile architecture, quality standards, security, and release readiness.
• Debug complex issues specific to iOS, Android, network configurations, and devices.
• Support mobile Continuous Integration/Continuous Deployment (CI/CD), application releases, monitoring, and store submission processes.
• Identify technical debt and work towards continuous improvement of the mobile codebase's architecture and reliability.
• Collaborate closely with product, design, and engineering teams to define scope, assess feasibility, identify risks, and evaluate technical options.
• Lead technical discussions and clearly explain complex engineering concepts to both technical and non-technical stakeholders.
• Mentor less experienced engineers through pairing, code reviews, and providing written guidance.
• Lead high-impact initiatives, unblock teammates, proactively identify and surface risks, and enhance engineering workflows.
