  • Demonstrated proficiency in threat modeling, secure coding practices, and risk analysis (SRA).
  • Relevant exposure and interactions with certification authorities (or delegates) and Stage Of Involvement meetings.
  • Relevant cybersecurity certifications (CISSP, GICSP, or equivalent) are a plus.
  • Ability to collaborate across multidisciplinary teams (architecture, software, safety, verification).
  • Excellent communication and leadership skills, with the ability to translate complex security concepts into actionable engineering practices.
