Enrichment of the STLA Brain platform architecture modelling capability STLA Brain is built as the central and evolutive electronics and software architecture for the next generation of Stellantis vehicles. Ensuring a continuity between the system architecture, the software architecture and code is a key aspect to the productivity and quality of the architecture practice. The SysML v2 modelling standard has been designed to support this continuity. Compared to SysML v1, SysML v2 can provide a standardized textual representation that matches the structural and behavioral graphical representations of system architectures. The textual representation enables Git-based configuration management and facilitates the continuity up to the applicative code. As a software architect and developer, you will enrich the STLA Brain platform architecture environment with architecture graphical modelling capabilities based on SysML v2. From these capabilities, users will be able to either work on graphical architecture or on the code and reach a synchronization between both approaches. The task will require to identify the stakeholders needs, to compare the potential approaches to satisfy those needs and then to implement bridges or transformations to the STLA Brain architecture environment so that the architecture modelling needs could be supported for structural and behavioral representations of the STLA Brain architecture. You will also contribute to the identification and implementation of opportunities for automation in the architecture design of the STLA Brain platform.
