The role

As Software Expert, you will be the key figure in defining and developing the system's software architecture, ensuring its robustness, maintainability and regulatory compliance throughout its entire lifecycle.
You will lead software development for high-security critical systems, in an environment where code quality, traceability and reliability are paramount.

What you'll do

  • Provide technical leadership to the software development team.
  • Define and evolve the system's software architecture.
  • Make key design decisions (frameworks, partitioning, communications, RTOS, etc.).
  • Ensure software quality: design, coding, testing and documentation.
  • Coordinate the development, integration and validation of the software with other disciplines (HW, systems, V&V).
  • Manage the complete software lifecycle (requirements → design → implementation → verification → certification).
  • Ensure compliance with standards and regulations applicable to critical software.
  • Participate in technical reviews and audits (PDR, CDR, TRR, etc.).
  • Act as the technical point of contact for software matters with clients and assessors.
  • Lead the resolution of complex technical problems at the software level.
  • Ensure the traceability and consistency of the software with system requirements.
  • Promote good development practices (clean code, testing, automation, CI/CD).
