• Desarrollar y mantener una app asegurando estabilidad, rendimiento y una experiencia de usuario fluida. • Implementar funcionalidades nativas en Java/Kotlin, incluyendo Geolocalización, Escaneo BLE y conexión con dispositivos IoT. • Integrar la aplicación con APIs y servicios cloud provistos por el equipo backend. • Participar en el desarrollo de flujos offline/online y en el manejo eficiente del estado local. • Incorporar notificaciones push, monitoreo y gestión de eventos de conectividad. • Colaborar con equipos de backend, QA e IoT para definición de requerimientos técnicos y validación de integraciones. • Aplicar buenas prácticas de desarrollo, testing unitario y control de calidad en cada entrega.

• Develop native Android applications using Kotlin, including leading development of features for our Identifi biometrics product. • Own and maintain Reveal’s Human Systems suite of ATAK plugins and integrations with our core products. • Work closely with SDK vendors to integrate functionality • Serve as the Android subject matter expert, guiding the engineering team on Android-specific projects and issues. • Advocate and drive user experience, security, and performance • Drive engineering quality through sound architecture, code reviews, and collaborative development practices. • Assist our business development and mission success teams with troubleshooting and technical issues

• Develop and optimize client-side RTC/live streaming interaction capabilities: co-streaming (joining/leaving the stream), audio routing, in-ear monitoring/audio mixing, weak network strategies, video quality/bitrate adaptation, and foreground/background/system interruption handling. • Deeply integrate third-party RTC SDKs (e.g., Agora) or in-house SDKs: integration, version upgrades, parameter management, compatibility and regression testing, online issue troubleshooting (via logs/callbacks/state machines). • Responsible for client stability and performance: audio/video threading models, CPU/memory/power optimization, end-to-end latency reduction, troubleshooting of complex issues such as stuttering, no audio/black screen. • Build client observability: key path instrumentation, QoS reporting, exception capture, automatic issue attribution (network/device/permissions/state machine/SDK). • Collaborate with server-side, testing, and operations teams: formulate stress testing plans, conduct rehearsals, and handle online incident emergency response and post-mortems.

• Lead the architecture, development, and delivery of Android applications for kiosk and mobile platforms • Partner with Design to create seamless, accessible user experiences for diverse rider populations • Implement secure payment flows and NFC-based interactions for fare collection and rider authentication • Define technical direction and best practices for the Android codebase • Mentor and grow team members as the mobile engineering function scales • Collaborate cross-functionally with backend, operations, and hardware teams to integrate with vehicle systems and backend services • Drive decisions on frameworks, tooling, and development workflows • Ensure reliability, performance, and quality through testing strategies and code review practices
