Job description

A fast-scaling semiconductor company is developing next-generation hardware and software products and is expanding its engineering team with an experienced Applied Cryptographer. The role combines theoretical cryptography with practical implementation, giving you the opportunity to design and analyse security solutions that will be integrated into cutting-edge products.

You will work on cryptographic algorithms, protocols and security architectures, identifying vulnerabilities and developing robust solutions across both hardware and software environments. The role also involves formal verification, security proofs, code review and security analysis, with a strong focus on building products that can meet demanding security assurance requirements.

Working closely with hardware and software engineering teams, you will help shape cryptographic designs from specification through implementation and integration. You will also stay close to the latest developments in cryptographic research, emerging attacks and post-quantum cryptography, helping identify opportunities and risks for future products.

Ideal candidates will have knowledge of:

• Master's or PhD in Computer Science, Mathematics, Computer Engineering, Cryptography or a related discipline
• Strong theoretical and practical knowledge of modern cryptography
• Symmetric and asymmetric cryptographic algorithms and protocols
• Post-quantum cryptography and emerging cryptographic standards
• Experience designing, implementing and maintaining cryptographic libraries
• Formal methods, formal verification and/or formal security proofs
• Strong mathematical foundations, including number theory, probability, complexity theory and abstract algebra
• Cryptographic security analysis and vulnerability assessment
• Secure software development, code reviews and security audits
• Hardware/software security integration within complex systems
• Security assurance, certification or standards-driven development
• Ability to translate complex cryptographic concepts into practical engineering solutions
• Strong technical documentation and communication skills
