• Design and build mobile features: Architect and implement complex features and interaction flows in our React Native app that are performant, accessible, and deliver exceptional user experiences. • Own technical delivery: Lead the technical design and implementation of complex features end-to-end — from product requirements through deployment and monitoring. • Drive app performance: Diagnose and resolve performance bottlenecks, optimize rendering, reduce bundle size, and improve the overall responsiveness of the mobile app. • Define technical direction: Propose and drive architectural decisions for your team’s mobile features, evaluating tradeoffs and communicating recommendations clearly. • Mentor and elevate: Provide hands-on mentorship to Software Engineers I, II, and III on your team and in the organization through code reviews, pairing, and technical guidance. • Improve engineering practices: Define, advocate for, and improve best practices around component architecture, testing, accessibility, and mobile deployment for your team. • Collaborate cross-functionally: Work closely with Product Managers, Designers, QA, and other engineering teams to translate product goals into well-scoped technical solutions. • Participate in on-call rotation: Share responsibility for production incidents, contributing to root cause analysis and long-term reliability improvements.

• Develop dynamic UIs using React, Next.js, and TypeScript, implementing SSR/SSG strategies and reusable component libraries. • Translate Figma designs into pixel-perfect, responsive interfaces with strong attention to UI details, spacing, edge cases, accessibility (WCAG), and cross-browser compatibility. • Integrate with backend APIs for AI features like face swap and lip sync, optimizing performance and handling state management. • Work in an existing production codebase, shipping small, clean PRs from detailed Linear/GitHub tickets with unit/integration tests. • Collaborate in Agile processes (standups, code reviews), proactively asking clarifying questions and demonstrating strong English communication.

• Develop features • Build and maintain reusable React components using TypeScript • Implement complex pages and flows (multi-step forms, wizards) • Develop dashboards with data visualization and real-time metrics • Create rich, interactive interfaces with a focus on performance and usability • Manage state and caching using TanStack React Query • Implement JWT-based authentication with refresh token rotation • Build forms using React Hook Form and Zod

• Resolve complex, escalated incidents and service requests through advanced troubleshooting and root cause analysis. • Partner with Tier 1, Tier 2, and Tier 4 support teams to drive issue resolution, providing mentorship and guidance. • Actively participate in change management activities and support reliable service delivery throughout the change lifecycle. • Maintain operational stability through scheduled system health checks, routine activities, and alert triage. • Analyze recurring issues to support problem management and contribute to continuous service improvement initiatives.
