Senior Android Native Developer

Senior Android Native Developer

1) Role Summary

Teceze is hiring a Senior Android Native Developer with 10+ years of native Android experience to design and build a Field Services mobile application used by technicians/engineers in the field. Experience delivering field services / workforce / FSM apps (work orders, asset servicing, offline data capture, geo tracking, signatures, photo evidence, scheduling) is a strong advantage.

2) Key Responsibilities

A) Native Android Development (Core)

• Build and maintain native Android apps using Kotlin (preferred) / Java with clean, scalable, testable code.
• Own end-to-end delivery: feature development, bug fixing, optimization, store releases, production support.

B) Field Services App Capabilities (Advantage Areas)

• Implement Work Order lifecycle: assign → accept → travel → arrive → job execution → parts/consumables → customer sign-off → closure.
• Build dynamic forms/checklists (config-driven) with validations, conditional logic, and attachments.
• Support offline-first operations:
• local persistence, background sync, conflict resolution, retry mechanisms
• partial sync and delta updates
• Enable geo-based workflows:
• maps, navigation handoff, geo-fencing (arrive/leave), location tagging
• route planning inputs (if provided by backend)
• Capture field evidence:
• photo/video, notes, barcode/QR scanning, signature capture
• Handle push notifications for work order updates, schedule changes, escalations.
• Ensure device reliability for harsh environments: battery optimization, background restrictions, intermittent networks.

C) Architecture & Engineering Excellence

• Apply MVVM/MVI / Clean Architecture, modularization, SOLID principles.
• Design robust state management for offline queues and sync jobs.
• Provide technical leadership: design reviews, code reviews, mentoring.

D) Integration & Data Handling

• Integrate REST APIs using Retrofit/OkHttp, strong error handling and resiliency.
• Implement secure storage using Room/DataStore and encryption where needed.
• Implement file upload flows (attachments) with retries and background upload.

E) Performance, Quality & Observability

• Optimize startup time, memory usage, network efficiency; eliminate ANRs/leaks.
• Implement testing strategy:
• Unit tests (JUnit, MockK/Mockito)
• UI tests (Espresso)
• Use analytics/crash monitoring (e.g., Firebase Crashlytics) and operational logs to improve stability.

F) Security & Compliance

• Follow OWASP Mobile practices, secure tokens/credentials, Android Keystore usage.
• Ensure privacy controls for location data, PII handling, consent prompts (as required).

G) CI/CD, Release & Deployment

• Maintain Gradle build variants/flavors, signing, versioning.
• Manage staged rollouts, feature flags, and release monitoring.
• Work with DevOps on CI pipelines (Jenkins/GitHub Actions/GitLab CI, as applicable).

3) Must-Have Skills

• 10+ years of native Android development experience
• Strong in Kotlin + Java, Android lifecycle, threading, background execution limits
• Jetpack: ViewModel, Navigation, Room, WorkManager, DataStore
• Coroutines + Flow (and RxJava exposure where applicable)
• DI: Hilt/Dagger/Koin
• Networking: Retrofit/OkHttp
• Testing: JUnit + Espresso
• Git + Agile/Scrum

4) Advantage (Preferred) Skills – Field Services / FSM

Any of the below will be considered a strong advantage:

• Experience building Field Services / Workforce / FSM apps (work orders, inspections, on-site service)
• Offline-first architectures, sync engines, conflict handling
• Maps & location: Google Maps SDK, geo-fencing, background location best practices
• Barcode/QR scanning (ML Kit / ZXing), signature capture, image compression & upload
• Device integrations: Bluetooth peripherals (printers/scanners), camera workflows
• Understanding of technician workflows, SLA/ETA concepts, job status tracking
