React native developer

Barcelona 32/40 H

Who are we?

Rinkel is a telecommunications scale-up founded in 2014 in the Netherlands. We offer a SaaS telephony platform that revolutionises the way freelancers and small businesses communicate. That includes building our very own Webphone in 2021, launching our integrations in early 2022, and receiving a €1 million investment to further expand our platform, and speed up our international ambitions. And there's so much more to us!

Our founders are techies, which means we don't consider software engineering an afterthought, a necessary evil or an expense. It's in our DNA. We're passionate about transforming a conservative telecom market, where most applications come from the Age of Dinosaurs. We do this by designing and building intuitive software by applying User Centered Design principles. From networking to mobile apps: everything is done in-house, which allows for rapid prototyping ("fail often, fail fast") and enables us to stay ahead of the competition.

Next to that, we have recently opened our first international office in Barcelona! Besides its hot tech scene which is a perfect match for us, it's also the first country where we will roll out our product! You will join a small team already working in the Barcelona office (which has sea view, and is located right next to the beach!). To ensure team synergy and to integrate new hires into our current team, employees will have the option to travel between Barcelona and Rotterdam on a regular basis.

About the role

Our current mobile iOS & Android apps are native apps built using Swift & Java. Designing 2 apps and maintaining 2 codebases doesn't match with our "fail often, fail fast" principle. Your job will be to build a new React Native app from the ground up, consolidate 2 codebases into 1 and work with the Product Owner and Designer to standardize the UI/UX across both platforms. You will ensure the quality of the app by writing automated tests, setup a CI/CD workflow and preemptive monitoring.

  • be part of a multidisciplinary team that ships great, intuitive software and knows what they're doing
