Job description

We are currently growing up and our Back-end team needs new colleagues. As we are a scale-up company, we have a lot of projects with new features to build! And one of them is to bring the Building Information Modelling (a.k.a. BIM) into our applications (web and mobile).

You will have the opportunity to prototype solutions, validate them in co-creation with Product manager and clients and push them forward to become production-ready for front-end applications to use them via our API.

You will also participate in building and maintaining new and existing microservices like document generation system, reporting tools, diagnostic tools like logging, monitoring and bug reporting.

As the business grows, you will have the opportunity to analyse, propose and implement a solution to bring 3D drawings, Budget and Planning information from the BIM model into our microservices and API.

As a team member you will participate in peer code reviews to ensure proper documentation on features and interoperability within the entire system
