Android Engineer

About the role

As an Android Engineer in SumUp's Hardware Tribe, you will be part of one of our small and highly skilled cross-functional teams and work together with Product Managers, Backend Engineers, iOS Engineers, Product Designers, and more. You will also be part of and collaborate on a global level with the broader Mobile chapter. You will deal with a variety of topics ranging from improving reliability of Bluetooth implementation within the Android SumUp app and the SumUp SDK, to implementing user-facing features such as screens to interact with card readers, to collaborating on developing technical roadmaps.

You should be a mobile engineer with a product mindset who can fully own the features you are working on and remain flexible with changing priorities.

The role is based on-site in our office in Berlin. We believe in the power of face-to-face conversations that happen organically when working next to one another.

About the team

You have probably used our card readers to buy a cappuccino or pay your hairdresser already. In Hardware, we are passionate about creating these beautifully designed card payment devices and accessories that enable our merchants to start, run, and grow their own businesses. In doing so, we deal with a diverse range of engineering topics - industrial and electronic design, embedded systems, all the way to mobile apps and backend services.

We believe in open communication and constant learning over strict rules. If you're looking for the chance to innovate and help millions of small independent merchants succeed - join us!

What you'll do

• Ship a variety of payment-related features and services within our Android ecosystem, supporting both our SDKs and the SuperApp
• Refactor and enhance existing solutions (including Bluetooth Low Energy connections, online/offline payments, and tap-to-pay functionality), and generally improve reliability and performance
• Work closely with the rest of the team to drive our roadmap and design our developer experience

You'll be great for this position if:

• You're comfortable with Kotlin, Java, and Android framework
• You have good knowledge of architectural design patterns such as MVVM and MVI, and experience ensuring modularized and scalable app architecture
• You know what to test, why to test it, and how to write flexible tests that won't break
• You care about user interaction, usability, and have attention to detail
• You strive for clean code, but also know how to be pragmatic when needed

Why you should join SumUp

• The opportunity to work on large scale fintech products used by millions of small businesses around the world
• A dedicated annual Learning & Development budget for attending conferences and/or advancing your career through further education
• Enrollment onto our virtual stock ownership program - you will own a stake in SumUp's future success
• A corporate pension scheme
• 28 days paid leave + 1 for birthday
• You'll attend global offsites and/or hackathons.
• You'd enjoy other great benefits such as Urban Sports Club subsidy, Kita placement assistance, subsidized office lunches and other location-tailored benefits, Babbel language platform subscription and more!
