Your employer: Building high-tech & greenfield products within a new team of software craftsmen

One of the most influential organizations of software engineers in the Dutch eco-system has given birth to a high-tech software product. Their product enables Engineers to obtain higher insights about the condition of software. In addition, it is possible to look back in time, and by looking at complex algorithms even in the future! In this way it is possible to solve the most complex issues within software engineering and to provide unique insights.

Because they are a spin-off of a successful technological leader, this translates into the lusts of a start-up but not the burden. They work very Agile / Scrum, contribute to multiple open-source projects and invest heavily in the development of their engineers with € 5,000 + per person per year training budget and 6 fixed training days where all highly intelligent engineers in the mother organization come together to share knowledge. In the department you will find an open and collaborative culture where everyone is as passionate about software development as you are. Their office is very close to the station of Utrecht and is therefore easily accessible by public transport and there are also parking spaces if you want to travel by car.

This is an excellent opportunity to work with React in a highly professional environment. In addition, you use Typescript, Rx.js (ReactiveX) and Three; of course in a fully equipped Test and DevOps environment.
