Company Description

Be the inventor and enabler of our business!

At Cuscal, our tech team are the hands and heart for what we do best. They’re the inventors, the creators, the enablers of our business. They turn ideas into reality. They test. They refine. They perfect.

We are looking for a Lead Cryptographic Engineer, to architect, implement, and manage enterprise-grade cryptographic systems, ensuring the confidentiality, integrity, and availability of sensitive data.

Job Description

What is this role about?

As the Lead Cryptographic Engineer, you will lead the design and deployment of cryptographic solutions, including encryption algorithms, secure key management, and Hardware Security Modules (HSM). By collaborating with cross-functional teams, you will ensure cryptographic standards align with evolving regulatory and security requirements, playing a critical role in safeguarding organisational assets.

Here’s some more insight into what you’ll work on,

• Cryptographic Architecture & Leadership:
  • Accountable for drive the design, implementation, and optimization of cryptographic solutions across the enterprise, ensuring robust protection for sensitive data.
  • Lead cryptography initiatives, including symmetric/asymmetric encryption, digital signatures, and key management protocols, embedding security by design.
  • Responsible for preparing reports for management, audit, and regulatory submissions, highlighting Crypto control efficacy, and incident response performance.
• HSM and Key Management Oversight:
  • Architect and manage HSM infrastructures, ensuring secure key generation, storage, rotation, and destruction.
  • Lead the deployment of secure key management systems (HSM, KMS) and cryptographic protocols across diverse environments, ensuring compliance with security policies.
• Advanced Encryption & Compliance Alignment:
  • Responsible for implementing advanced encryption standards (AES, RSA, ECC) and cryptographic algorithms aligned with regulatory requirements (e.g., PCI DSS, NIST).
  • Responsible for encryption strategies are both cutting-edge and compliant with evolving global standards.
• Cryptography Lifecycle Management:
  • Oversee the end-to-end cryptographic lifecycle, ensuring secure implementation from design through maintenance.

Qualifications

What can you bring?

• 7+ years of experience in cybersecurity, with a focus on management of cryptographic engineering, incident response, and threat intelligence.
• Extensive experience in cryptographic systems architecture, including deep knowledge of encryption algorithms (AES, RSA, ECC), key management protocols (PKI, HSM), and cryptographic protocols (TLS, IPsec, SSH).
• Proven hands-on experience managing HSMs (e.g., Thales, SafeNet) and KMS solutions across cloud and on-premises environments, ensuring secure key management and cryptographic compliance.
• Hands-on experience with scripting languages (e.g., Python, PowerShell, Bash).
• Strong understanding of advanced exploitation techniques and attack vectors (e.g., buffer overflows, SQL injection, APTs, privilege escalation). Expert at conducting threat modelling (STRIDE, DREAD) and applying countermeasures to mitigate threats.
