The focus is on the backend – the data structure, business logic and API development. You often work together with one or more front-end (say UI/UX) developers and you keep your finger on the pulse for the finishing of the entire module. 

Independent delivery of back-end modules; your tasks:

• Make your own technical analysis (functional analysis = input for your tasks) 
• Provide a correct estimate for the development time/effort 
• Independently develop data structure & business logic 
• Consultation with and collaboration in the Agile Team in which you works around APIs / interfacing with front-end
• Ensure and document the test procedure of your module(s) + perform unit tests yourself 
• Correct documentation of code & agreements (techn.analyse, API/interface,...) - All this under the supervision of the Project Manager who directs delivery.



  • Higher education in ICT or a relevant direction (or equivalent in relevant work experience) 

  • At least 5 years experience in software development 

  • Good oral and written communication skills in both Dutch and English. 

  • Knowledge of and experience with object-oriented programming is an absolute must 

  • Intersystems ObjectScript (Cache) is used – if you already have experience in this, that is a plus – but given the similarities with other (object-oriented) programming languages, not a must

  • Knowledge/experience with SQL, NoSQL databases/structures 

  • Knowledge/experience with Java 

  • Knowledge/experience with Go 

  • Knowledge/experience with Micro Services architecture
