Descripción

🎯 ¿Qué vas a hacer?

Construir nuestra app Android desde cero, manteniendo paridad de features con la app iOS existente (SwiftUI nativo, en fase avanzada).

En concreto:

- Arquitectura limpia en Kotlin + Jetpack Compose (nada de XML layouts heredados)

- Implementar criptografía moderna: Android Keystore, BiometricPrompt, EncryptedSharedPreferences, posiblemente Tink o libsodium según caso

- Comunicación en tiempo real: WebSocket con reconexión robusta, manejo de estado con StateFlow/SharedFlow

- Integración con APIs REST (Perl/CGI backend), HMAC signing, JWT handling

- Escaneo QR con CameraX + ML Kit

- NFC + BLE: lectura de chips, advertising, GATT connections, emparejamiento seguro

- Almacenamiento local cifrado (SQLCipher o equivalente Android)

- CallKit-equivalente Android: ConnectionService + Telecom framework para llamadas VoIP

- Push notifications (FCM con encriptación payload)

- Testing: unit tests con JUnit5/MockK, UI tests con Compose Testing, integración con Maestro o Detox

- Performance profiling con Android Profiler (memory leaks, ANRs, battery drain)

- Code reviews bidireccionales — tu código revisa el mío, el mío revisa el tuyo

✅ Lo que buscamos técnicamente

Imprescindible:

- Kotlin avanzado: coroutines, Flow, scope functions, sealed classes, delegation patterns

- Jetpack Compose sólido: recomposition understanding, side effects (LaunchedEffect, DisposableEffect), state hoisting, custom modifiers

- Arquitectura: MVVM o MVI, Clean Architecture básica, DI con Hilt/Koin

- Git fluido: rebase, cherry-pick, resolver conflictos sin llorar

- Android SDK nivel API 26+, AndroidX, Gradle Kotlin DSL

- REST, JSON (https://jobeax.com/link/QZi6IvwaNV4yPOi5 o Moshi), manejo de errores HTTP

- Inglés técnico para leer RFCs, specs, código fuente de libs

Valorable (bonus points):

- Experiencia con criptografía real (no solo llamar SHA-256): key derivation, AEAD, signing/verification flows

- Ktor client (nosotros preferimos esto sobre Retrofit por flexibilidad)

- Room con migraciones no triviales

- WorkManager para sync en background

- CameraX customizations (overlays, análisis de frames en vivo)

- Experiencia con accesibilidad (TalkBack, contraste, navegación por teclado)

- Haber publicado algo real en Play Store (incluso una tontería propia cuenta)

- Contribuciones open source públicas

- Familiaridad con estándares de identidad digital (OID4VP, SD-JWT, mDoc, eIDAS) — si ya los conoces, eres oro; si no, te los enseñamos

Plus humanos:

- Alergia al código espagueti y a los "TODOs" de hace 3 años

- Capacidad de decir "esto está mal" — incluso sobre tu propio código de ayer — y refactorizarlo sin drama

- Mentalidad de leer antes de escribir: sabes buscar en la documentación antes de preguntar

- Curiosidad real por criptografía, privacidad, seguridad, sistemas distribuidos

- Cabeza clara: sin alcohol, sin drogas, sin humo durante el trabajo. Único vicio permitido: café con código

💼 Lo que vas a encontrar aquí

- Mentoring directo con el fundador (40+ años programando, desde Assembler hasta SwiftUI actual)

- Cero mánagers intermedios — decisiones técnicas en la mesa y en 5 min, no en Jira

- Arquitectura limpia desde día 1 — no estás heredando deuda técnica de 5 años

- Equipamiento profesional: Mac potente, monitores 4K, dispositivos Android reales para testing

- Impacto real: tu código estará en manos de usuarios reales en toda Europa y resto del mundo

- Proyectos paralelos (música, otras apps) — si te interesa algo fuera de Android, se puede explorar

- Pausas de café que funcionan como staff-meeting. Después, otra vez al tajo ☕

- Mar a 15 minutos

🎤 Una cosa más

No buscamos ejecutores. Buscamos a alguien que cuestione, mejore y proponga sin que se lo pida nadie. Si esperas instrucciones detalladas para cada línea de código, esto no es lo tuyo. Si te va construir algo desde el principio que importe de verdad, hablamos.
