Cryptography Hardware Engineer

Job description / Role Job Type Full Time Job Location Dubai, UAE Nationality Any Nationality Salary 55000 - 70000 AED Gender Not Specified Arabic Fluency Not Specified Job Function IT - Software & Web Development Company Industry Telecoms A satellite communications business in Dubai is hiring a Cryptography Engineer to build and harden secure comms for real-world, mission-critical systems. If you’ve shipped crypto into constrained environments (embedded / RF / satcom / defence-grade networks) and you care about doing it properly — threat models, key management, secure boot, the lot — this one’s for you. What you’ll do

• Design and implement cryptographic protocols for secure satellite communications (data-in-transit + data-at-rest)
• Build and maintain key management approaches (generation, rotation, storage, revocation) across devices and services
• Work on secure authentication, encryption, g, and integrity for links and payloads
• Threat model systems end-to-end and partner with engineering teams to close real vulnerabilities (not theoretical ones)
• Support security reviews, audits, and pen-test remediation with clear technical ownership
• Document designs so they’re maintainable, testable, and defensible What we’re looking for
• Strong hands-on cryptography engineering experience (not just security generalist work)
• Solid understanding of modern crypto primitives and when to use them (and when not to)
• Experience with secure key storage (HSMs, TPMs, secure elements, KMS) and practical key lifecycle management
• Comfortable working close to the metal when needed (embedded, firmware, constrained compute, performance trade-offs)
• Ability to explain crypto decisions clearly to non-crypto engineers and leadership Nice to have (not required)
• Satcom, RF, aerospace/defence, or high-assurance environments
• Experience with secure boot, attestation, hardware-backed identity
• Familiarity with compliance/security standards used in regulated environments
• Experience building secure protocols or contributing to security-critical libraries Why this role
• Dubai-based satcom environment with real technical problems and real-world constraints
• High ownership: you’ll shape security architecture, not just review it
• Competitive package: AED 55k–70k/month depending on depth and relevance Requirements:
• 8–12 years in security/cryptography engineering, with 3–5 years specifically owning crypto designs in production systems
• Background in satcom / aerospace / defence / telecoms / embedded security (one of these), comfortable in high-assurance environments
• Mix of hands-on implementation + architecture: can write code, review code, and defend design decisions in front of auditors and engineering leadership Core experience (must-have)
• Cryptographic engineering (real implementation, not theory-only):
• Encryption, g, integrity, authentication, secure session establishment
• Practical use of modern primitives (e.g., AES-GCM/ChaCha20-Poly1305
