About Skyscanner Everyone loves travelling, but planning is not without its challenges. That's why we've spent 20 years building tools that turn travel-planning chaos into a breeze. Today, around 100 million travellers count on us every month to skip the whole “47 browser tabs open” phase and find flights, cars, and hotels quickly and easily. Joining Skyscanner means becoming part of a global brand that's striving to become the planet's go-to travel hack accessible for all. Our vision? To be the world's number one travel ally. (Ambitious? Yes, but, hey, that's what got us here.) About the role Hybrid This is your chance to shape how millions of travellers experience ads — without making them feel like, well… ads. You’ll join our fast-growing App Monetisation team, building seamless, native advertising experiences that actually belong in the journey. Sitting at the crossroads of travel, data, and commercial tech, you’ll help us design smart, privacy-first solutions that keep things relevant, performant, and (dare we say) enjoyable. It’s part engineering craft, part experimentation playground, and part “how can we make this even better?” energy. What you'll be doing Building Native Ad Experiences: Craft scalable, high-quality advertising components within the Android app that feel like a natural part of the journey, not a detour Collaborating Across Teams: Partner with product, design, backend, data and commercial teams to deliver experiences that balance user value and business impact Evolving Ad Architecture: Contribute to ad-serving systems, creative rendering, and placement experimentation to keep things fast, flexible, and future-ready Driving Performance & Measurement: Own tracking, attribution and performance insights to help us understand what works (and what really works) Championing Privacy-First Development: Build with user trust front of mind, ensuring compliance with GDPR and best-in-class consent practices (e.g. Google Play policies, Privacy Sandbox readiness) Experimenting & Iterating: Use testing, analytics and feature flags to continuously refine and improve ad experiences at scale Communicating with Clarity: Share ideas, context and technical decisions openly, helping teams move faster and smarter together About you Android Craftsperson: You’ve built complex, high-quality Android apps using Kotlin and are comfortable with modern Android development practices Architecture-Savvy: MVVM, Clean Architecture, modularisation… these aren’t just buzzwords to you — they’re how you build maintainable, scalable apps UI Fluent: Comfortable working with Jetpack Compose (and/or Views) to create polished, performant user experiences Ad Tech Curious: You’ve either worked with advertising tech or you’re genuinely excited to dive in and learn fast Quality-Driven: You write modular, testable code with performance, accessibility and scalability baked in Experimentation-Minded: Familiar with CI/CD, analytics and feature flagging — and you love using data to guide decisions Collaborative & Curious: You enjoy working across disciplines, sharing knowledge, and constantly levelling up yourself and those around you What it's like here We are the real deal — no corporate gloss, no empty promises.
