Job description

Are you an expert in cryptography and secure key management? Do you thrive on designing robust security solutions for complex enterprise environments? We’re looking for a Cybersecurity Solution Architect with deep expertise in SSH key management and advanced cryptographic practices to lead the design and delivery of secure architectures across large-scale transformation programmes.

In this role, you’ll own end-to-end solution design, create high-level architecture patterns, and ensure alignment with strategic direction. You’ll work closely with enterprise architects, senior stakeholders, and technical teams to deliver secure, efficient, and cost-effective designs. This is a unique opportunity to influence key decisions, provide technical thought leadership, and drive innovation in identity, access, and cryptography for next-generation platforms.

Key Responsibilities

• Design and deliver secure solution architectures with a strong focus on SSH key lifecycle management and cryptographic controls.
• Define and publish architecture patterns, decision records, and design deviations.
• Identify and mitigate technical risks and dependencies throughout the project lifecycle.
• Present solutions at design authorities and engage senior leadership for approvals.
• Act as a subject matter expert in cryptography and secure access management.
• Promote strong documentation and governance practices.

Cybersecurity Expertise:

• Proven experience in SSH key management, including:
• Secure generation, rotation, and storage of SSH keys.
• Implementing automated SSH key lifecycle solutions.

Deep technical knowledge in cryptography, including:

• PKI and certificate management.
• Symmetric & asymmetric encryption algorithms.
• Secure key exchange protocols.
• Hash functions and integrity verification.

• Strong understanding of authentication protocols (Kerberos, OAuth, SAML).
• Experience with Privileged Access Management (PAM) and Federated Identity.
• Broad IT background with ability to communicate effectively with non-security SMEs.
• Experience in large-scale IT transformation programmes.

Tools & Technologies:

• Familiarity with BizzDesign, Archi, or UML for high-level designs.
• Proficiency in Jira and Confluence for project and documentation management.
