Python Developer [Medior/Senior] Central-North Portugal, PT

We are looking for an experienced Python developer to join our team.

// or in other words the master of building API’s and backend services using Python [bonus for previous AI experience] 

Who are we?

We are the DEUS initiative, and we are all about exploring AI in the service of humanity. No, we are not calling ourselves gods(!), but our name is a reference to ‘deus ex machina’ (or god from the machine in Latin). We believe that artificial intelligence technologies such as machine learning, computer vision and natural language processing will have a massive impact on the way we live, and we want to make sure that we create a positive impact on the world with these AI services.

As a happy coincidence, DEUS is also an acronym representing the quadrivium of key disciplines we believe are important to building successful AI-powered services: Data / Engineering / User-experience design / Strategy.

DEUS is a new initiative, but the founders have been working together very successfully for years, so there is a comfortable family feel to the company. We have an amazing set of international client partnerships (and projects/challenges). Our headquarters is located in the heart of the city centre of Amsterdam. We also have a team in Portugal that is based out of the beautiful city of Porto with an office close to the beach,  and our Spanish team is based out of the charming center of A Coruña!

We are dedicated to making a friendly and inclusive workplace. To put it bluntly, there is an unwritten ‘no assholes’ policy that applies to both ourselves and our clients, as we always want to enjoy our team dynamic. We do trips, conferences and events together on a regular basis, and we are always committed to cultivating a company that embraces differences. We strongly believe in flexibility, and you will be given a lot of freedom while translating complicated problems into easy-to-use products.
