Senior Mobile Developer (iOS/Android)

Fulltime / Location: Flexible

About the role:

Our mobile apps are natively built by the current Engineering team using Java/Swift. They include most of the features of our platforms' Web version, but not all of them. Your first job will be to add the missing features and to take a critical look at the current GUI/workflows and improve where needed.

For the long term, our ambition is to migrate the existing apps to a cross platform solution. You will research framework options (like React Native & Flutter) and build and demo Proof of Concepts. Then, depending on the decision that is made, start the migration process. All while making sure our current user base keeps a flawless mobile experience by implementing automatic testing and (pre-emptive) monitoring.

About Bereik:

Bereik is a telecommunications start-up founded in 2014 in the Netherlands. We offer a SaaS telephony platform that revolutionises the way freelancers and small businesses communicate. After 7 years of finding product market fit (over 7.500 active users), we are now transitioning to scale-up.

Our passion is designing and building great software. How? By not just doing what everyone else does; but by reinventing the wheel; because we can. Our platform is completely designed, built, and managed in-house using bleeding-edge technology. This in turn makes us flexible and scalable.
