Senior Software Engineer, Android

Senior Software Engineer (Android)

At Swile, we provide innovative solutions in various areas such as Fintech, Travel, HR, and Employee Benefits to more than 5.5 million users in 85,000 companies in France and Brazil.

Senior Mobile Software Engineers for the Android platform at Swile are responsible for delivering the best experience to all our end users and ensuring that our Android app performs well even on older devices, remains secure, and is stable.

We are looking for a Senior Software Engineer (Android) with deep Android expertise experience to elevate platforms and lead Swile Apps to the best possible user experience. You will own user-facing features end-to-end, raise the quality bar, and push the org to operate with a consistently high bar and high performance.

We also expect you to be able to deliver well-documented, tested, high-performance code in Kotlin and Java, following best development practices and ensuring that everyone on your team does the same through code reviews, always aiming to improve the quality of your team's deliveries.

Your day to day activities:

• Own and ship Android features from problem framing → design → implementation → rollout → monitoring.
• Set and enforce mobile quality targets (e.g., crash-free >99.9%, cold-start p95 down quarter over quarter, accessibility compliance, secure software).
• Lead mobile architecture and standards (modularization, design system components, networking, telemetry).
• Ship safely using feature flags, staged rollouts, server-driven config, kill switches, and clear rollback plans.
• Instrument, monitor, and alert on critical journeys (errors, latency, jank, memory/battery, app size).
• Drive cross-platform parity by defining shared foundations with iOS/Web and closing experience gaps.
• Accelerate others via design/code reviews, mentoring senior engineers, CI/build-time reductions, and clear docs.
• Partner tightly with Product/Design/Data; prototype, experiment, and make decisions grounded in user signals.

Requirements:

• 6+ years building large-scale Android apps; track record of shipping high-impact user features.
• Expert in Kotlin; strong Gradle expertise; strong Jetpack Compose/XML (ViewBinding) and Java interoperability; solid concurrency (Coroutines/Flow) and Android Profiler.
• Depth in networking (REST/Retrofit), offline/caching (Room), secure storage (EncryptedSharedPreferences/Keystore), privacy, and accessibility.
• Proven release/quality engineering: JUnit/Espresso/snapshot testing, CI/CD (Bitrise), staged rollouts, feature flags, and reliable rollback.
• Demonstrated org-level influence: multi-team designs, standards adoption, mentoring engineers, raising execution pace.
• Crisp written/spoken communication; partners effectively with Product, Design, and Backend; data-driven decisions.
• C1 English.

Preferred requirements:

• Master's degree, PhD, or equivalent in Computer Science, Computer Engineering, or related fields.
• Experience in cross-platform development.
