Senior Android Developer KMP for Kiosk appVerified as a real position

Who we’re looking for

• Deep, production-level Android and Kotlin experience — you've shipped non-trivial apps and owned them past launch.
• Strong understanding of Kotlin Multiplatform — code-sharing strategies, expect/actual, and where the boundaries between shared and platform-specific code should sit.
• Track record of designing modular, maintainable architectures (MVVM, MVI, or Clean Architecture) on greenfield or actively evolving codebases.
• Comfort with Jetpack Compose for non-trivial UIs.
• Experience with GraphQL clients in mobile contexts — bonus if it's Apollo.
• B2 English (written and spoken).
• Ability to work independently in a remote, fast-paced environment.

What you’ll do

• Architect and build the new Kiosk app on Kotlin Multiplatform, contributing to shared logic for ticket booking, inventory, and platform integrations.
• Design the SDK surface that powers white-labeling, enabling our clients — from major global attractions to smaller operators — to customize the Kiosk experience to match their brand.
• Build the touch-optimized Kiosk UI in Jetpack Compose, with performance and reliability suitable for always-on, single-purpose devices.
• Implement smart caching and request strategies that keep the Kiosk responsive over real-world venue networks, while treating the product as online-first.
• Write and maintain unit and integration tests for the Kiosk codebase, working with QA to shape the broader automation and hardware-mocking strategy.
• Identify bottlenecks and bugs in the Kiosk runtime and drive them to resolution.
• Collaborate with the Hardware/Platform team to integrate their peripheral abstractions cleanly into the Kiosk.

About the position

Imagine standing at the top of the Empire State Building, taking in the breathtaking view. From the online booking to the seamless entry, every part of your ticketing experience was designed and supported by Ventrata. An industry-leading SaaS platform that helps attractions, tours, and activities to create memorable experiences. Backed by a passionate team, headquartered in London and with offices in Brno, Lisbon, and remote teams worldwide, we’re expanding rapidly across multiple markets and verticals. Our mission is to help businesses of all sizes scale and grow while preserving their unique identity and spirit. Be a part of something extraordinary, where your ideas and contributions truly matter. Let’s shape the future of travel together. Ventrata is looking for a Senior Android Developer to join our team and change the way tours and tickets are sold worldwide. The ideal candidate will have experience working in a startup environment and be capable of working independently as part of our remote team. We're over 150 people and growing fast, but small enough that the work you ship is visible — to your team, to leadership, and to the customers using it. The role is EU remote, but you can also join us in our Brno offices (Czech Republic). About the Terminal team Ventrata enables attractions, tours, and activities operators to manage their businesses and sell through all available channels (online, offline, on-street, and distribution). Our aim is that our clients never have to leave Ventrata when they're using us. You will be joining our Terminal team, which focuses on hardware-integrated solutions that end users interact with directly — think buying from a kiosk, or validating their tickets at a turnstile. This position will push the boundaries of what's possible with Kotlin Multiplatform; your primary focus will be development of our new kiosk. This project is an important part of Ventrata and is used by end customers all around the world. The Challenge: "Greenfield in a Box" This isn't a standard app-building role. You'll be joining our Terminal team on a fresh Kotlin Multiplatform project that's already underway — a new Kiosk app being built from the ground up to replace the kiosk functionality currently bundled inside our Flutter-based Terminal codebase. Once shipped, the kiosk logic can be retired from the Flutter project, streamlining both codebases. You'll be building the foundation for a system that isn't just used by our clients, but is designed from day one to be consumable as an SDK by third parties. How we work We hire people who think for themselves and own what they ship. You don't need a 5-page spec to get started. You ask the right questions, push back when requirements don't make sense, and own the outcome. You are the owner of the delivery — you can push it, tweak it, and ask questions. You know when to be deliberate and take safe steps, and when to take action. You can deliver. We are heavily integrating AI into our process, using tools like Claude Code for code generation. This doesn't mean we delegate our work to agent systems — we use them to improve delivery and accelerate development. AI augments your creativity and speed; it doesn't replace your judgment or ownership.
