Java Developer


Apply now

At TimeSeries we would like to expand our development team with a talented Java developer. Do you have experience working with Big Data solutions and software development within this area? You’re the one we’re looking for! 

Job description

As one of our developers you’re expected to design, build, maintain and run our software in a DevOps capacity. Your attention will be divided between improving and expanding our various templates and building and maintaining custom client solutions that work together with these templates. All our solutions are run as a collection of microservices that work together to process large quantities of data, solve computational intensive problems and serve these to first and third party consumers.

Future development is a team effort where everybody is encouraged to participate. New features and improvements are dictated by a combination of our needs and those of our clients. We prefer to use Open Source projects over Enterprise solutions any day. All development happens in-house, so we can leverage on everybody’s affinities and expertise. We consider our team to be our greatest asset and value teamwork over individual knowledge.

What we’re looking for

You love to develop robust software to overcome complex challenges
You love to immerse yourself in the technical complexities of the software you’re building. You like to explore possible solutions and find the one that’s just right. TimeSeries leverages the inquisitive nature of our team and applies these to find and solve the functional challenges our customers face. We look to analyze and overcome these challenges together.

You have proven yourself in the field
While a solid background in IT education is helpful, we take on anyone that has a proven track record in the IT industry. We believe that the growth in our field does not step, nor necessarily have to start during your education.

Your brains!
We’re looking for the best people on the market, those that want to keep up with the ever changing landscape of software development. We constantly revisit what we have built before and ask ourselves how we could’ve built it better. We expect the same from you.
