Role description

KAYAK, part of Booking Holdings (NASDAQ: BKNG), is the world’s leading travel search engine. With billions of queries across our platforms, we help people find their perfect flight, stay, rental car and vacation package. We’re also transforming business travel with a new corporate travel solution, KAYAK for Business.

As an employee of KAYAK, you will be part of a travel company that operates a portfolio of global metasearch brands including momondo, Cheapflights and HotelsCombined, among others. From start-up to industry leader, innovation is in our DNA and every employee has an opportunity to make their mark. Our focus is on building the best travel search engine to make it easier for everyone to experience the world.

KAYAK is seeking a
Staff Product Designer, Mobile
to own the design direction across our apps and lead the craft of every designer who works on them. This is a senior individual contributor role with manager-level scope: you carry the design direction and UX/UI patterns across three teams (Apps Meta, Apps Retention, and Mobile Design Systems) while still designing and shipping yourself. You set the quality bar for all Apps design output, you hold it across teams, and you keep engineering pointed at the right work. You are the technical lead for apps design, accountable for the quality and velocity of what the apps designers produce, without managing them directly.

This role is required to work from our Berlin office 3 days per week.
In This Role, You Will

  • Own the design direction and the UX/UI pattern system across the apps surface. Navigation, mental models, and UI consistency cut across Apps Meta, Retention, and Design Systems at once, and you hold that cross-cutting direction so three teams ship one coherent experience rather than three versions of it.
  • Set the quality standard for apps design and hold it as a discipline, not a project. Make the bar visible where teams miss it, and close gaps across teams that you did not personally create. You are accountable for the quality and velocity of all apps design output.
  • Run planning and discovery for all three teams. Break multi-team, loosely defined problems into clear design direction the designers can run with.
  • Partner with the Director of Product for Apps and the apps PMs on core initiatives, influencing roadmap and prioritization through design rationale.
  • Lead native craft across iOS and Android. Set the approach for resizability, foldables, new screen sizes, and solve how KAYAK responds to platform chrome shifts like Liquid Glass and Material 3 Expressive.
  • Lead the design approach for mobile AI features: how we integrate AI into the apps, the UI, and the navigation around it, so it lands as a native part of the experience.
  • Drive the brand differentiation work for our portfolio of hero brands apps like momondo to ensure local market dominance.
  • Raise the ceiling for the other apps designers through critique, shared standards, and patterns they build on. Designers should get better by working alongside you and using what you establish, not only through direct mentorship.

Required Skills

  • 10+ years in product design, with a portfolio of shipped, high-impact mobile work at consumer scale.
  • Deep native expertise across iOS and Android. Mastery of Apple HIG and Material Design, and the judgment to know when to converge and when to honor platform difference. Hands-on experience with resizability, foldables, and iPad, and a point of view on platform chrome directions like Liquid Glass and Material 3 Expressive.
  • A track record of raising design quality across a discipline beyond your own projects, through standards you set, critiques you ran, or systems others still use.
  • Experience driving design direction across multiple teams or product areas, with the ability to influence without authority.
  • Experience building or evolving mobile design systems and scalable patterns.
  • Strong with Figma, and fluent with AI-assisted design and prototyping tooling (for example Claude Code or Cursor).
  • Comfort using data and research to set direction and measure outcomes.

Please Apply If You Have

  • Experience managing or leading designers. This is an IC role, so it counts as a strong plus rather than a requirement.
  • Driven design vision across teams in a way you can tie to outcomes, not just deliverables.
  • Formal education in design (BA, BFA, MFA) or equivalent practical experience.

Benefits And Perks

  • Work from (almost) anywhere for up to 20 days per year
  • Focus on mental health and well-being:
  • Company-paid therapy sessions through SpringHealth
  • Company-paid subscription to HeadSpace
  • Company-wide week off a year - the whole team fully recharges (and returns without a pile-up of work!)
  • No meeting Fridays
  • Paid parental leave
  • Paid volunteer time
  • Focus on your career growth:
  • Development Dollars
  • Leadership development
  • Access to thousands of on-demand e-learnings
  • Travel Discounts
  • Employee Resource Groups
  • 6 weeks paid vacation + a day off for your birthday
  • Free lunch 2 days per week
  • Pension plan contributions
  • Public transportation subsidies
  • Bike leasing program
  • Monthly social events, Thursday happy hours, sports teams
  • An awesome office in Friedrichshain, Berlin

Inclusion
At KAYAK, we want everyone to have the space to grow, share ideas and do great work. That’s why we’re focused on hiring the best talent from all walks of life and experiences, supporting them well and making sure no one feels like they have to fit a mold to belong here.

Need any adjustments for the interview, application or on the job? No problem - just give us a heads-up. We’ve got you.

Role description

Build the platform where Belgium feels at home.
For over 30 years, Immoweb has been more than just a platform; we are the digital heartbeat of the Belgian real estate market. From first apartments to forever homes, we bridge the gap between dreams and reality for millions of users every month.

Our mission: to inspire, guide and close every home move in Belgium. We make real estate fast, transparent, and stress-free through world-class technology and human-centric support. We are dedicated to connecting people with their property goals, ensuring that at Immoweb, your work has an immediate, nationwide impact from day one.

Your Mission
Who we are
Immoweb is Belgium's leading real estate portal, part of AVIV Group, Europe's largest network of digital real estate marketplaces. Every month, hundreds of thousands of people use our iOS app to search, save, and get alerted about the properties that matter to them. We're currently modernising our native codebase — moving from an older UIKit/MVVM stack to a leaner, more testable Swift 6 architecture — while keeping the app running reliably for our existing user base.

The Seeker squad
You'll join Seeker, a full-stack squad (iOS, Android, Web, Backend, Design) that owns the end-to-end property search and discovery experience: search, filters, saved searches and alerts, and the property detail page. We work in close collaboration with product and design, ship through CI/CD, and care about shipping quality features that scale to hundreds of thousands of daily users.

What You'll Do

  • Design and build native iOS features for the Immoweb app, working closely with our Android, Web, Backend, and Design counterparts on shared feature sets.
  • Contribute to our ongoing migration from UIKit/legacy patterns to SwiftUI, @Observable, and Point-Free's modular architecture libraries.
  • Write clean, testable code (XCTest / Swift Testing) and review your teammates' work.
  • Continuously improve app quality, performance, and stability for a large, active user base.
  • Ship through our CI/CD pipeline in close collaboration with product managers.
  • Be a driving force behind new features — search relevance, alerts, personalisation — and technical improvements alike.
  • Share knowledge with the team and help raise the bar on iOS engineering practices across Immoweb.

What You Bring

  • Solid, hands-on experience building production iOS apps in Swift, ideally including Swift 6 and iOS 18.
  • Strong SwiftUI experience; comfort with @Observable and modern state management patterns.
  • Good understanding of Swift Concurrency (async/await); exposure to RxSwift is a plus, as parts of our codebase are mid-migration.
  • Familiarity with, or willingness to adopt, Point-Free's à la carte libraries (swift-dependencies, swift-sharing, swift-navigation, swift-case-paths).
  • Experience consuming RESTful APIs; familiarity with Moya is a plus.
  • A solid grasp of software architecture and Clean Architecture principles.
  • Basic knowledge of unit and UI testing (XCTest / Swift Testing).
  • Comfort working with Git and collaborative workflows (GitHub).
  • Excellent communication skills; you're a team player who shares knowledge openly.
  • English is mandatory; French or Dutch are strong assets given our Belgian market.

Nice to have

  • Experience with Swift Package Manager.
  • Familiarity with the Composable Architecture (TCA) or similar unidirectional architectures.
  • Experience with A/B testing and product analytics/tracking.
  • Experience with Bitrise or similar CI/CD tooling.
  • Knowledge of accessibility best practices.
  • Experience contributing to or consuming a design system.
  • Familiarity with Jira and Confluence; experience working in Scrum.

What We Offer

  • A friendly, quality-first engineering culture where you'll help modernise a widely-used app.
  • Real ownership over features used by hundreds of thousands of people every day.
  • Hybrid working, with the option to be based in Brussels or Bucharest.
  • Opportunities for growth — training, conferences, and mentorship within a full-stack squad.
  • The autonomy to work in the way that makes you most productive, and a say in the tools you use.
