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)

• Powering smarter decisions: As a Senior Software Engineer in our Backspin squad, you’ll help make experimentation simple, scalable, and seriously impactful across Skyscanner.
• Building at scale: You’ll work on our in-house experimentation platform — the kind that sits proudly alongside the likes of Netflix, Airbnb, and Spotify.
• Operating at the crossroads: This role lives at the intersection of Web Engineering, Data Engineering, and Data Science, where things are complex (in a good way).
• Driving real impact: Your work will directly influence how teams test ideas, learn faster, and make higher-quality decisions backed by rock-solid data.
• Owning big problems: From design through delivery, you’ll take the lead on solving technically rich, business-critical challenges.
• Collaborating widely: You’ll partner closely with product managers, data scientists, and engineers across Skyscanner to shape the future of experimentation.
• Growing the platform: As experimentation continues to scale year on year, you’ll help evolve both our tech and our ways of working.

What you'll be doing

• Designing distributed systems: You’ll build and maintain high-performance, secure, and scalable systems that underpin our global experimentation platform.

• Advancing experimentation: You’ll develop features that help teams run, monitor, and analyse experiments — from segmented insights to multi-platform testing.

• Raising the quality bar: You’ll ensure our systems are reliable, observable, and built to handle experimentation at serious scale.

• Collaborating cross-functionally: You’ll work hand-in-hand with product, data science, and platform teams to align tools with real user and business needs.

• Mentoring others: You’ll support and guide junior engineers, sharing knowledge and helping the whole squad level up.

• Championing best practice: You’ll drive clean architecture, thoughtful design, and continuous improvement across the codebase.

• Shaping the future: You’ll help influence the technical direction of our experimentation platform as it continues to grow and evolve.

About you

• Distributed systems savvy: You have strong experience designing and building scalable, resilient distributed systems.

• Technically versatile: You’re comfortable working with Java and Node.js, and you’re happy getting your hands dirty across the stack.

• Data-aware: You bring familiarity with data pipelines, and bonus points if you’ve worked with Python, PySpark, Databricks, or AWS.

• Platform-minded: You enjoy building tools and platforms that empower other teams to move faster and smarter.

• Collaborative by nature: You communicate clearly, work well across disciplines, and enjoy solving problems together.

• A natural mentor: You like helping others grow, sharing feedback, and raising engineering standards around you.

• Curious and driven: You’re excited by experimentation, learning, and tackling complex problems in new ways.
