Via is on a mission to create public transportation systems that provide far greater access to jobs, healthcare, and education. Our platform serves as the technology backbone for modern transit networks, transforming antiquated and siloed public transportation systems into smart, data-driven, and efficient digital networks. With hundreds of agency partners around the world, Via is recognized as the leading transportation technology and service provider globally.

As a Senior Mobile Cross-Platform Engineer at Via, you'll be a core member of the rider mobile team, owning the mobile experience that millions of riders depend on every day - from booking rides and managing accounts to the underlying mobile infrastructure that makes it all work seamlessly. You'll work across both native Android and iOS and our cross-platform Flutter codebase, collaborating closely with designers, backend engineers, and product managers who care deeply about the quality of what they ship. If you're a mobile engineer who takes pride in building polished, high-performance experiences across platforms and wants to see your work used at real scale, this is the role for you.

**This is a hybrid position with the expectation that you will be onsite in NYC 2-3 days a week.**

About the Role:

• Collaborate closely with designers, backend engineers, and product managers in order to deliver our high-quality, user-friendly rider application
• Own the development and continuous improvement of Via's rider mobile apps across platforms - building new features across booking, account management, and the core rider journey while keeping the experience fast, reliable, and intuitive.
• Work primarily in Flutter for cross-platform development while contributing to native Android and iOS codebases where needed, making pragmatic decisions about when to go cross-platform and when to go native
• Architect and evolve the mobile infrastructure services that power Via's apps, making thoughtful decisions about app architecture patterns, performance optimization, and memory management that the whole team benefits from
• Diagnose and resolve critical production issues under pressure, minimising disruption to riders and acting as a key line of defence when things go wrong in live environments
• Mentor and guide engineers on the team - sharing your expertise across platforms, reviewing code thoughtfully, and helping others grow

About You:

• 5+ years of mobile development experience, with strong hands-on experience in cross-platform frameworks - Flutter experience is a strong advantage - alongside solid native development experience in Android (Kotlin) or iOS (Swift)
• Comfortable working across both cross-platform and native codebases, with a good instinct for when each approach is the right tool for the job
• Strong grasp of mobile app architecture patterns, performance optimization, and concurrent programming - whether that's Kotlin Coroutines, Swift’s async-await, or Dart's async patterns in Flutter
• Experienced with mobile frameworks including Location Services and Google Maps API, and familiar with third-party mapping tools such as Mapbox
• A natural collaborator and mentor - you take ownership of your work, share knowledge generously, and make the engineers around you better
• Proactive and genuinely curious about new technologies - you don't wait to be told what to improve, and you bring energy and ideas to the team

Compensation and Benefits (US only)

• Final salary will be determined by the candidate’s experience, knowledge, and skills. Salary reflected does not include equity or variable pay, where applicable.
• Salary Range: $160,000 - $200,000
• We are proud to offer a generous and comprehensive benefits package, including free medical plans, 401K matching, catered lunch on Wednesdays, and many other perks.

There has never been a more exciting time to be on the cutting edge of public mobility. Ready to join the ride?
