Block Programming Editor Internship

Location

Paris or Montpellier, France

Context

DecisionBrain is a young international company that develops and sells software solutions for decision support.

The internship will preferably take place in our offices in Paris (10e) or Montpellier (Millénaire). Remote work is possible if imposed by regulation.

Decision Optimization Center

Decisionbrain develops a platform to create, deploy and maintain fully scalable decision support solutions. Quickly, easily, efficiently. DOC accelerates the creation and deployment of decision support solutions.It is written in Java for the back-end and in Angular for the front-end, and relies on a number of technologies such as Spring, Docker, etc.

Subject

One of the feature in the DOC platform is a scripting language dedicated to orchestrating decision processes. Using this language, the platform developer can write scripts in which s/he requests inputs from the user, triggers optimization tasks, retrieves data from a database or saves it back, etc.

For the time being, the scripting language has no concrete syntax. The only way to write a script is writing some Java code that creates the objects that compose the abstract syntax tree of your script. Among the various possibilities for a concrete syntax, a block-based one is the focus of this internship.

The purpose of this internship is to investigate and develop a visual script editor based on Google's Blockly library (https://developers.google.com/blockly/). The expected results include:

  • Definition of the graphical lexicon to match the scripting language statements and expressions.
  • Depending on the cases, this will either consist in configuring existing. Blockly components, or in writing new ones.
  • Integration of the editor based on the Blockly library in our Angular
  • Definition of a persistence and interchange format for scripts, based on the XML documents produced by Blockly.
  • Development of the script management features on the Java side.
  • Skills

    The internship subject touches a variety of technology. Most of its complexity comes from that, and probably a significant part of its interest, too. The candidate is not expected to fully master all of these technologies, but to have strong skills in a sufficient number of them to be able to acquire the missing ones. The technologies in question include:

    • Back-end development, preferably in Java. Use of a dependency injection framework such as Spring. Familiarity with databases, in particular MongoDB.
    • Front-end development, preferably with Angular.
    • Versioning systems, preferably Git. Build tools such as Gradle or Maven.

    Beyond technical skills, the candidate is expected to be autonomous and able to collaborate efficiently with other team members. Reasonable levels in spoken French and written English are mandatory.
