• Perform detailed cybersecurity assessments of ATC systems, subsystems, and COTS components. • Map component‑level controls to applicable cybersecurity frameworks, primarily NIST SP 800‑53, as well as complementary frameworks (e.g., NIST CSF, ISO 27001, or aviation‑specific guidelines when applicable). • Identify deficiencies, evaluate risk impact on safety‑critical functions, and define remediation recommendations. • Produce assessment reports, risk matrices, and control implementation summaries. • Contribute to the creation, documentation, and maintenance of System Security Plans for ATC systems across their life cycle. - • Describe system boundaries, data flows, interfaces, security controls, operational environments, and residual risks. • Ensure consistency with regulatory, customer, and internal compliance requirements. • Collaborate with systems engineering and certification teams to prepare security deliverables for audits and approval processes. • Design secure architectures for ATC systems, addressing confidentiality, integrity, availability, traceability, and resilience. • Define system‑level and component‑level security controls, zoning concepts, segmentation, and protective monitoring strategies. • Produce architecture diagrams, security models, and interface control documents. • Align solutions with aviation safety‑critical constraints, real‑time performance requirements, and applicable cybersecurity policies. • Work closely with the product engineering teams based in Europe and North America. • Support R&D and engineering teams by translating security requirements into actionable engineering tasks. • Review system designs, prototypes, and interfaces for compliance with security standards. • Provide guidance on closing identified security gaps through secure coding practices, architectural changes, or control enhancement. • Communicate complex cybersecurity concepts in a clear, engineering‑friendly manner. • Familiarity in IP networking, VoIP, and RF communications or similar.
