ALTEN Romania is part of the ALTEN Group , Leader in IT and Engineering Consulting . We develop innovative and durable technical solutions that fulfill the needs of our local and international partners.

About the project:

We work in an agile way, organised in sprints, and we release very often.

Our focus is always on our clients: we work hard to make everything as simple and easy to use as possible for them.

We expect the code we write to be well organised and to respect our current architecture, so that the product stays consistent and easy to maintain as it grows.

You will:

• Own complex features end-to-end across the presentation and data layers

• Convert design mockups (Figma) into fully native screens

• Make architecture decisions and lead the refactoring of legacy code

• Design clean APIs and module boundaries that scale across a large codebase

• Write well-organised code that respects our current architecture

• Champion testing, performance, accessibility, and application security

Key technical skills and areas of expertise include:

• Languages: Kotlin

• Architecture: clean, modular architecture with MVP and MVVM presentation patterns

• Dependency injection: Dagger2

• UI: Jetpack Compose for new screens, classic Android Views for existing ones, plus a unified design system and animations (Lottie, Rive)

• Asynchronous and reactive: RxJava (v1 and v3) and Kotlin Coroutines with Flow

• Data and networking: Realm for local persistence, Retrofit and OkHttp for consuming REST APIs

• Platform features: biometric authentication, Maps and location, PDF rendering

• Security, identity and analytics: anti-fraud and KYC tooling (Revelock, Onfido), analytics platforms (Adjust, Salesforce, Medallia, Countly) and Firebase

• Quality and CI: Detekt, SonarQube, JUnit, Mockito, MockK, Robolectric, Roborazzi screenshot testing and JaCoCo coverage

To ensure success in this role, you need the following experience and skills:

• Strong knowledge and understanding of the Android SDK and app lifecycle

• A solid grasp of data structures and algorithms

• Experience working with databases and consuming REST APIs

• The ability to write maintainable and reusable software

• A strong sense of when refactoring is needed, and how to do it safely

• Dependency injection with Dagger2 or Hilt

• Reactive programming with RxJava and/or Coroutines and Flow

• Jetpack Compose and modern declarative UI

• Modular and clean architecture at scale

• MVP and MVVM presentation patterns

• Local persistence (Realm)

• Automated testing, including unit, instrumentation, and screenshot testing
