Your Name
Your Passion & Expertise
Jobs @ Codeflix
Our team consists of experienced full-stack software developers who have years of experience in programming. We are a small team that enjoys what we do. Thanks to our in-depth cross-industry experience, our customers can be sure of receiving an excellent service.
Our employees appreciate the charm of a small company with a large customer base.
At Codeflix, we mostly work remotely and flexibly in order to be able to reconcile our professional obligations with our private and family lives.
Our Core Values
We are characterised by professionalism, reliability and flexibility in what we do. In addition, appreciation and trust in our collaboration are important to us, as are a constructive feedback and error culture, open communication and a sensible level of transparency.
Our Team
We also enjoy spending quality time together outside of our projects. Our last team events focussed on delicious food, joint challenges in the escape room and the odd sporting activity. Voluntary and informal, of course.
