Senior System Engineer – Product Security, Crypto and Cyber

In this role you will define and govern the security architecture for Helsing’s CA-1 platform, spanning hardware and software design to regulatory compliance. You will craft the aircraft-level security concept, manage intra- and inter-vehicle communications security, and lead platform cryptographic management. You will engage with customers and national authorities to demonstrate Helsing’s security engineering capability. This position combines systems rigor with deep cryptography and cyber expertise to deliver mission-critical security on a high-profile defence programme.
