Are you the awesome self-steering backender we’re looking for at Cobra? With some front-end affinity? You have the overall view from the architecture. You have a lot of experience with SQL, JavaScript and PHP, but actually each programming language/application has its own logic, and you usually master it in no time. Your dedication, communication skills and basic knowledge make you a valuable addition to the team. You are always open and honest about what your expectations are and can deliver a good planning.

What we do

We provide a complete solution for the digital customer journey of companies. In other words, effective websites, handy apps and super fast WiFi with which our clients are successful. No standard work, but tailor-made digital applications that make customers happy. From devising an effective digital strategy to building and managing these online solutions.

Doing new things

You’re not averse to working with a CMS like WordPress, but you’re also ready for more challenging projects that you build from scratch. Think for example of a new type of dashboard. In principle you work independently, but there are always ‘helplines’ within the company with which you can spar or ask for help.

Your impact is big

Cobra works with a small dedicated team full of greats in their profession. So your impact in the team and at Cobra is immediate.

That is why we at Cobra are looking for enterprising, independent people. We expect our people to be able to do more than just their specialty. You are broadly deployable. You’re not just a puppet who does the work, but an active part of the future of the company.

With us you get the chance to form your own role, because we prefer to get the best out of you. To be able to do that, we want you to enjoy your work. To alternate the hard work, we also like to laugh at the office. But only for really good jokes.

But just as seriously: we document and test everything in detail, and that’s what we expect from you as well. Quality is the top priority.

You have knowledge of:

  • Programming and scripting, HTML, SQL, PHP, Javascript, GIT
  • Vue.js
  • Laravel
  • Building API’s
  • Software testing and deployment processes
  • SQL, mySQL
  • Google Analytics
  • Linux servers
