This is the moment to start working at the The Speer Agency. We are one of the fastest growing job agencies in the Netherlands. Our succes formula is simple. We find you a  new job in no time !

This position is for working on-site or remote (our only concern is to have the best onboard).


Your Mission:

We are looking for an experienced mobile developer that can help a team to grow in numbers and knowledge, as we build  our product to be used by our partners. If you see yourself fit in the below requirements description, are passionate about building products and working with bright and highly productive teams, this role could be a great match.


Who are we?

You'll be joining a small but growing team of people who believe in building a great product for our customers and have the skills to make it happen.

We relish hard problems, both concerning business, design, and development. And we truly enjoy coming up with solutions to make everyone happy, from the customers, who depend on our product, to our team, as our work depends on each other. The fact that we’re very into the “80-20” mindset makes this even more interesting, as time to execute will also play a big factor in the solutions we find.

We are curious people, and with some much responsibility our customers put in our hands, we look to every detail and make sure we find every way things can break or fail.

A big part of our culture is learning. We cannot emphasize too much how important this is to us. We need always to be learning, and what we learn we have to be able to convey to others be it via email or in person. Thus, being a good communicator (which is different from being an extrovert) is an essential attribute for us.

If you are a person with strong opinions, weakly held, who wants to have a big impact and both an avid learner and teacher you’ll do great here.
