Principal Security Consultant Engineer

Reference: 6juqlx0dz7shvg6uyz95

We are seeking a Principal Security Consultant Engineer to provide senior technical leadership across complex cybersecurity engagements. In this role, you will assess security architectures, identify vulnerabilities and risks, and design practical, scalable solutions that strengthen the resilience of systems, applications, networks, and cloud environments. You will work closely with technical teams, business stakeholders, and delivery partners to translate security requirements into clear recommendations and measurable improvements.

Your responsibilities will include leading security assessments, threat modelling, architecture reviews, penetration testing oversight, and incident-readiness activities. You will develop detailed reports, risk treatments, security strategies, and implementation roadmaps, while ensuring that recommendations align with recognised industry standards and regulatory expectations. You will also contribute to security governance, technical policy development, control reviews, and assurance programmes. As a principal-level specialist, you will mentor consultants and engineers, support business development and proposals, present findings to senior stakeholders, and help establish consistent methods, tools, and quality standards across engagements.

The successful candidate will have substantial experience in security consulting, engineering, or architecture, with a strong understanding of enterprise infrastructure, identity and access management, secure software development, cloud security, network defence, and vulnerability management. Experience applying frameworks such as ISO 27001, NIST, CIS Controls, SABSA, or similar is desirable. Professional certifications such as CISSP, CISM, CCSP, GIAC, or relevant cloud and security credentials would be advantageous. You will be an analytical and confident communicator who can explain complex technical issues to both specialist and non-specialist audiences, manage competing priorities, and influence decisions without direct authority. A proactive approach, sound professional judgement, and commitment to continuous learning are essential.
