I supported the implementation of new features, performed validation tasks and ensured traceability in accordance with ECSS and CCSDS engineering standards. The role required attention to detail, structured documentation and collaboration with multidisciplinary teams to deliver reliable, mission‑critical software for aerospace applications.
