# Senior System Engineer - Product Security, Crypto and Cyber

- **Company:** Helsing GmbH
- **Location:** München, Germany (Remote available)
- **Experience:** Expert
- **Contract:** Temporary contract
- **Skills:** Systems Engineering, Cyber Security, Electronic Data Interchange (EDI), Key Management, Software Architecture, Software Engineering, Software Security, Vulnerability Analysis
- **Published:** September 10, 2026
- **Apply:** https://www.indeed.com/viewjob?jk=32bb83b1b685501b

## About the Role

* Have developed cryptographic management concepts for complex platforms, including crypto key management design and lifecycle governance
 * Have conducted structured vulnerability analysis and adversarial threat assessments on safety- or mission-critical networked systems
 * Have defined communication security designs for intra- and inter-platform data exchange in a defence or government context
 * Are professionally fluent in German, with the ability to engage with national security authorities, regulators and customers in technical and formal settings

Note: We operate in an industry where women, as well as other minority groups, are systematically under-represented. We encourage you to apply even if you don't meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.

Nice to Have

 * Familiarity with IFF systems and their associated security and certification requirements
 * Experience designing erase and zeroise functions at aircraft or platform level
 * Background in airborne mission systems or avionics security, including familiarity with DO-326A / ED-202A
 * Exposure to Common Criteria evaluation processes or equivalent assurance frameworks
 * Experience supporting security authority interactions as a named security engineering lead

## Description

Helsing's CA-1 programme is building the software-defined intelligence layer for one of Europe's most advanced combat aircraft. As a Senior Systems Engineer specialising in Product Security, Cryptography and Cyber, you will be responsible for defining and governing the security architecture of the entire platform - from the requirements that shape hardware and software design, through to the compliance artefacts that satisfy national and NATO authority expectations., This is not a role confined to policy or paperwork. You will develop the aircraft security concept from first principles, own the design of intra- and inter-vehicle communication security, and lead Helsing's approach to platform-level cryptographic management, including functions such as erase and zeroise. You will work directly with customers - requirements workshops, technical reviews, solution showcases - and with German national security authorities, making professional fluency in German an operational necessity. The candidate who will thrive here brings a rare combination of systems engineering rigour, deep cryptographic and cyber knowledge, and the ability to translate complex security requirements into engineering reality on a programme that genuinely matters.

The day-to-day

 * Guide hardware and software design teams through security requirements specification and architectural decisions, ensuring compliance with national and NATO-level security regulations across the CA-1 programme
 * Develop and own the aircraft-level security concept, derived from applicable rules, regulations and standards, and maintain it as the authoritative reference across the programme
 * Define and implement engineering design processes applicable to product security, establishing repeatable, auditable workflows that can scale with the programme
 * Create and maintain the compliance artefacts required by national and NATO security authorities, ensuring Helsing's security posture is demonstrable and defensible at all stages of delivery
 * Design the security architecture for intra- and inter-vehicle communications, covering both on-board and off-board interfaces across the platform
 * Develop the design concept for aircraft-level security functions, including erase and zeroise, ensuring operational integrity under all mission conditions
 * Conduct vulnerability analysis and adversarial testing on platform systems, translating findings into actionable engineering mitigations
 * Define the platform cryptographic management concept, including crypto key management architecture and lifecycle processes
 * Engage directly with defence customers - including the Bundeswehr and other national authorities - to capture requirements, present solutions, and represent Helsing's security engineering capability with authority
