Your future role
As part of the SML400 GP-SSI Design team in Charleroi, this Software Designer role offers a unique opportunity to play a central part in the evolution and enhancement of the SML400 GP-SSI system, with a special focus on the innovative CIXL-T product — the central safety brain of the system. This product is at the heart of our technology roadmap, with exciting developments planned up to 2028.
Your initial mission will be to recover and master the in-depth knowledge of the SML400 GP-SSI CIXL-T product, currently managed by the ALSTOM St Ouen site, and to ensure its successful transfer to the Charleroi site. You will work with a generic hardware safety platform (two variants) and a dedicated application software, becoming a key reference for both. Additionally, you will gain expertise in the “DataPrep” tool, which is essential for configuring the product and supporting future updates.
This position allows you to be involved in the full software lifecycle: understanding components, implementing changes, maintaining and upgrading features, and performing design testing. You will collaborate closely with other team members to guarantee the quality and relevance of deliverables, all within a dynamic and supportive environment.
Based mainly in Charleroi, the role includes regular interactions with the St Ouen site (especially during knowledge transfer workshops) and offers a flexible working arrangement between on-site and remote work. Over time, you may also contribute your expertise to other software teams within the SML400 GP-SSI programme, supporting the overall system planning and development.
