Director of Security Engineering - Permanent - London

£130,000 - £150,000 + performance bonus & corporate benefits
Hybrid - Central London

This one is a corker and in my opinion one of the most exciting perm roles i've had the pleasure of working on in the last decade. I will be taking printed copies of CVs to present to the client next Tuesday morning so if you're up for it, send me message and we'll have a chat.

I have been engaged on a search for a Director of Security Engineering reporting directly into the CISO of a high growth, international technology business. This is an opportunity for a security leader who wants genuine ownership, influence and the ability to shape the future direction of security across a modern SaaS organisation.

This is one for someone who can operate strategically with executive stakeholders whilst remaining credible with engineers, architects and technical teams. You'll be joining at a particularly interesting point in the organisation's journey, helping to scale security capabilities, embed security into product and engineering functions, strengthen detection and response capabilities and shape how the business approaches AI security and emerging technology risks.

If you're a security leader who wants to own Security Engineering, SecOps, AppSec, Cloud Security and AI Security in a business where security is viewed as an enabler rather than a blocker reach out to me ASAP. It would be particularly suited to existing Directors, Heads of Security Engineering, Heads of Security Operations, Senior Security Managers or technically minded security leaders who are looking for a broader remit and greater impact.

Experience within SaaS, technology, cloud native or product led organisations would be especially valuable.

We are seeking an experienced Cyber Security Director to provide strategic and day‑to‑day leadership across a wide range of cybersecurity initiatives for our clients. This role is central to shaping, delivering, and overseeing high‑impact security programmes, while advising senior stakeholders on risk, resilience, and organisational security maturity.

You will work closely with executive teams, technology leaders, and operational stakeholders to design and implement cybersecurity strategies, lead crisis and incident response efforts, and guide clients through complex security challenges. The role requires a strong consulting mindset, the ability to manage multiple engagements simultaneously, and a passion for driving measurable improvement in client environments.

Serve as a trusted advisor to executive‑level stakeholders, providing guidance on cybersecurity strategy, governance, and risk management.

Lead the development of security transformation roadmaps, maturity assessments, and long‑term resilience programmes.

Support clients during crisis situations, major incidents, and high‑severity security events, ensuring clear communication and structured response.

Oversee the design and execution of cybersecurity initiatives, including audits, assessments, remediation programmes, and interim leadership engagements.

Provide direction across multiple workstreams, ensuring alignment with client objectives, regulatory requirements, and industry best practices.

Ensure quality, consistency, and timely delivery of all consulting outputs.

Manage multiple client engagements simultaneously, balancing strategic oversight with hands‑on involvement where required.

Build strong, long‑term relationships with clients, understanding their business needs and identifying opportunities to enhance security posture.

Support client expansion efforts by identifying new service opportunities and contributing to proposal development.

Contribute to the development of new cybersecurity service offerings, methodologies, and frameworks.

Provide insights on emerging threats, regulatory changes, and technology trends to help clients stay ahead of evolving risks.

Represent the organisation in client workshops, executive briefings, and industry discussions.

Work closely with cross‑functional teams including technical consultants, incident responders, architects, and project managers.

Mentor junior consultants and contribute to capability development within the cybersecurity practice.

Promote a culture of excellence, innovation, and continuous improvement.

Proven experience as a senior cybersecurity professional, ideally in a consulting, advisory, or client‑facing leadership role.

Strong understanding of cybersecurity frameworks, governance models, risk management, and security operations.

Experience managing multiple engagements and delivering outcomes in complex, fast‑paced environments.

Exposure to client growth, account development, or solution expansion is beneficial but not mandatory.

Strong communication and presentation skills, with the ability to engage confidently with senior stakeholders.

Excellent organisational and time‑management abilities, capable of handling multiple priorities simultaneously.

Problem‑solving mindset with the ability to translate technical issues into business‑focused recommendations.

Hands‑on experience with CRM tools and consulting delivery processes.

Solutions‑oriented, proactive, and commercially aware.

Comfortable operating in high‑pressure environments and managing sensitive client situations.

Collaborative, adaptable, and committed to driving growth within the consulting practice.
