Junior Ruby Developer


Junior Ruby Developer

Being a Junior Ruby Developer at T-Mobile is an exciting and varied job that touches different facets of both the customer fulfilment & assurance processes and the network infrastructure here at T-Mobile. Do you have a passion for software development and want to become a Ruby coding expert? And did you already had a look at Elixir? We can offer you the opportunity to work with emerging technologies and a modern telecom network!

Wat ga je doen?

Your responsibility as a developer is to create and improve software together with your team to automate the network configuration, service fulfilment and service assurance processes, so our customers get the best experience when using those services. Your team will be responsible for the complete software development cycle. From gathering requirements, designing the solution, develop, test and deploy (via CI/CD of course) to the aftercare, DevOps style.

Waar kom je te werken?

The department we called ‘Digital Orchestration’ is the gateway between the commercial customer services and the implementation of those in our networks and on our service platforms. This encompasses internet access, TV and voice services for our consumer domain and internet access, connectivity and hosted voice/mobile connect services for our extended business line. The SCRUM team that you’ll join is developing and maintaining software that handles all the transactions towards our growing fixed network and service platforms. We believe in on the job training. Next to that we offer also coaching from senior developers.

Barriers prevent people from being their best selves. That’s why it’s our mission to break through these barriers in the telecom industry. Everyone should benefit from a connected life, don’t you agree? The Fixed Network department makes this happen. Software changes, customer connections, hosting and security; we’ve got it all covered. Small teams, professionals from around the world, and an impressive challenger quality. How else can we support more than a thousand internal and millions of external users? This is where we make an impact.

We believe in a connected life. For our customers and our employees. You create your workspace. At the office? You’ll be in good company! At home? Be sure to do the dishes while you’re there. The more people, places, and things are connected, the more value is created. For all of us.

You can also look forward to seriously funny colleagues, regular exercise with a Health Club, and, of course, a salary, holiday leave, and generous bonuses. Still not enough? Check our website!

Curious to find out more about the T-Mobile culture? Follow us on social media and discover how we keep challenging the world. Or you’re always welcome to stop by for a coffee at our office.

Wat breng je mee?

  • A bachelor’s degree in computer science or another relevant study or equivalent knowledge gathered by work experience;
  • Experience with one or more technologies like Sidekiq, Git, Docker, Ruby on Rails, AWS, K8’s or Azure Cloud;
  • A getting things done mentality, combined by being flexible; 
  • A preference for working in an open and dynamic work culture;
  • A passion for clean code;
  • Feel responsible and own what you create;

But if you miss a lot of the above, but you are smart and well educated, have a strong technical profile and would love to become a software developer in an intriguing technology driven world, consider the option to join as a junior and get on-the-job training by some of the best.

So if:

  • You want to learn how to become a software engineer;
  • You want to become an expert in Ruby;
  • You come up with smarter and better ideas to automate the network;
  • You can improve our cloud first approach;
  • We get maintainable and adaptable code;
  • We have happy customers that can change their telecom services on the fly;

Then maybe this is the right opportunity for you!

Wat bieden we jou?

At T-Mobile, diversity is celebrated and we are committed to providing an inclusive work environment with equal opportunities for all our employees!

There is a lot that’s possible within T-Mobile but you have to take the initiative. Be enthusiastic! Are you missing something or could something be improved? Go ahead, do it differently! It’s great when you learn from us but it is equally great when we learn from you!

Our first contact will probably be by phone (off course), for a short chat with one of our recruiters. Next there can be an interview which usually will be conducted digitally online where you will meet a manager and/or a couple of colleagues. Still interested? Then there will be a second interview (digital or face to face in the office) which will be more in-depth. When afterwards you and us are still enthusiastic, we will present you an offer in which you can become the newest member of Team Magenta!

Next to about 2000 enthusiastic colleagues we also provide the following:

  • A good salary
  • Freedom to work
  • 30 + 1 vacation days on a full-time basis, plus public holidays
  • 3 interchangeable public holidays of your choice according to religion or country of origin.
  • Collective Bonus Scheme
  • Progressive Pension Plan
  • Personal annual learning budget
  • Discount on T-Mobile subscriptions Mobile and Internet & TV @ home
  • Hybrid work environment, both at home and in the office
  • Workshops, sporting outings, T-Schnee, cozy drinks and fun parties organized by Young T-Mobile.

Wat ga je bij ons leren?

At T-Mobile it goes without saying to keep personal development going. We have a variety of platforms to help you with your development. You are responsible in doing so and so you determine how, what and when you choose to develop. We will support you in this. So how do we do that?

YOU are in the lead, so old fashioned performance reviews and such, is not something we do. You keep your manager and colleagues informed about your goals and development. We call those discussions “Great conversations”. More about how this works you can see via:

Still reading? Then we’ll leave you with a little bit about T-Mobile

Although we might not be a start-up (we do have awesome macchiato’s), we do behave like one. T-Mobile is a challenger. For over twenty years, we have been providing our customers with the service they deserve. And these days we’re on a mission to make a connected life completely carefree. We want to get rid of constraints that prevent people from being their best selves sooner rather than later. That is carefree living as it is meant to be. Because it can be.

So, … Are you just as excited about us and this role, as we are about having you on the team? Great, then we probably are a good match. Applying is very easy. Just sent your CV and motivational cover letter via the button/link and give yourself the opportunity to be part of one of the best providers of The Netherlands where you could be part of the T-Mobile family for a long time with a bright future.

This is not a project, we are in it for the long run! Aren’t you!?
