Job description

At Saily, we’re removing the hassle of staying connected while traveling — no roaming fees, no plastic SIM cards, just lightning-fast, secure mobile data in 200+ destinations. Saily has millions of paying customers and hundreds of thousands of travelers browsing through Saily at any given moment.

To build the best product for our customers we foster AI-native Product Engineering culture, where:

  • The Engineer is the builder, responsible for solving customer problems end-to-end (idea to production).
  • AI Agents are the enablers who write most of the code and solve repeatable tasks to help the Engineers maximize their impact.
  • Everyone contributes to making Saily effective by suggesting new areas for improvement to delegate to agents and then implementing the changes.
  • Curiosity, learning, and sharing are everyone's responsibility.
  • Customer, having a comfortable, connected, hassle‑free journey, is never lost from the focus.

We value growth over comfort, contribution over hierarchy, and impact over process. At Saily, we believe in giving sharp people context, autonomy, and AI as their multiplier to allow them to just do their best work.

Main Responsibilities
  • You will contribute as a team member to the development effort for Saily for Android devices. This includes interacting with our existing backend REST APIs, providing feedback based on mobile needs, and working with our web, backend, and UX teams to build new features and enhance the quality of existing ones. You will also coordinate with our Product Owners and QA/Support team to ensure our Android app consistently retains a high standard of quality.
  • Debug and resolve issues reported by users and internal testing teams.
  • Be a part of a growing development team that consists of engineers with a Kotlin background and QAs.
  • Stay up to date with cutting‑edge tools, patterns, and methodologies to ensure excellent quality of the code. It’s all about that code.
  • Drive the adoption of AI across mobile platform and our broader tech stack. You will be the one auditing the AI landscape, baking it into our daily workflows and refactoring our project structures so agentic coding actually feels seamless.
Core Requirements
  • 3+ years of extensive Android development.
  • Fluent with Kotlin, MVVM Clean architecture, Room or SQLite databases, and reactive programming libraries such as Coroutines.
  • Knowledge of the latest trends and libraries in the Android ecosystem, such as Jetpack Compose and Hilt.
  • Debug and resolve issues reported by users and internal testing teams.
  • Experience with debugging tools and solving problems reported by users.
  • Experience in writing unit and UI tests.
  • Excellent knowledge of Android APIs and SDK.
  • Experience working with large codebases.
Bonus Points For
  • Networking knowledge and previous experience in developing telecommunication solutions.
  • Experience with the agile methodology.
Tools You Will Use
  • Kotlin
  • Android Studio
  • Hilt
  • Coroutines
  • Jetpack Compose
Salary Ranges
  • Gross salary: 25,500 — 34,000 PLN/month
