Paris, Île-de-France SumUp Temps plein

About the team

SumUp's Point-of-Sale (POS) solution empowers cafes, shops, bars, hair salons, and other businesses to operate efficiently and grow. It offers a wide range of features, including product catalogs, inventory management, business analytics, compliance support, and loyalty tools.

Our POS solution integrates seamlessly into the SumUp SuperApp, which supports both our proprietary register hardware and mobile devices like tablets and phones.

As a Senior Android Developer, you'll collaborate with a dynamic, cross-functional team of Product Managers, Product Designers, Engineering Managers, and fellow engineers.

About the role

We're evolving toward a Kotlin Multiplatform (KMP) strategy, enabling shared development across Android and iOS. In this role, you'll learn, refine, and help implement this technology, shaping the future of our mobile apps.

You're a developer who values user-centric design, precision, and seamless collaboration. You bring structure to communication and thrive in a cross-functional environment. 

What you'll do

  • Build new features for the item catalog within the SumUp SuperApp
  • Help improve the architecture of the application and contribute to our Kotlin Multiplatform strategy
  • Enhance and maintain our unified android app, distributed across 60+ countries, ensuring high-quality, scalable solutions
  • Shape the product's evolution by identifying opportunities for improvement and contributing to daily decision-making
  • Write thorough documentation and implement robust testing for features before shipping
  • Collaborate closely with Designer, Product Manager and Android engineers to deliver a unified UX experience across platforms

You'll thrive in this role if:

  • You have 8+ years experience in mobile engineering with Android and Kotlin.
  • You have 2+ years of experience working with Jetpack Compose.
  • You have a solid understanding of software design patterns (e.g., MVVM, MVI) and expertise in building modular, scalable app architectures.
  • You have good knowledge of reactive programming (Flow, Coroutines and Concurrency).
  • You have a strong grasp of testing best practices: knowing what to test, why, and how to write resilient tests.
  • You strive for clean code, and you are flexible to balance pragmatism and perfection.
  • You have a keen interest in multi-platform development using Kotlin Multiplatform.
Why You Should Join SumUp

  • Opportunity to work with a truly global, multicultural team (3,000+ people from 93 countries across 4 continents).

  • Competitive salary package & virtual stock option programme.

  • Learning & development budget for conferences and external training.

  • Corporate pension scheme, 25 days' paid leave, and other great benefits.

  • A passionate, purpose-driven team that achieves incredible results together.

  • Regular breakfasts, team events, office parties & sports activities.

  • Break4me – 1-month sabbatical after 3 years of service.
