Cyber Security Manager in London

Elixirr International plc is a global consulting firm with a bold ambition: to become the best consulting firm in the world. Founded in 2009, we’ve grown from a single vision into a powerhouse of entrepreneurial talent, delivering boardroom strategy through to execution. After IPO-ing on AIM in July 2020, Elixirr moved to the Main Market of the London Stock Exchange in July 2025. Our market cap has grown from £98 million to over £350 million – a testament to our differentiated approach and relentless pursuit of excellence.

We’re looking for exceptional talent to join us on this exciting growth journey and shape the future of consulting.

Location: You can be based in London or New York. Our headquarters are in Central London. Our east coast hub is based in New York City.

Job Summary: We’re building the best consulting firm in the world. We’re looking for outstanding client-facing Cyber Security Managers with 4-6 years’ experience to join our global team. You will be ready (and excited) to hit the ground running, make a real impact on our client’s business and help shape their thinking from day one.

Responsibilities:

• Manage client-facing cyber security consulting engagements, delivering strategic advice across cyber risk, resilience, governance, and operating models.
• Develop and maintain strong client relationships with senior stakeholders (CISO, CIO, CRO, etc.).
• Translate complex cyber threats and issues into clear business language and actionable recommendations.
• Shape and contribute to Elixirr’s growing cyber proposition – including thought leadership, tools, and methodologies.
• Support business development, including identifying opportunities, drafting proposals, and pitching solutions.
• Contribute to internal capability building, including team development and knowledge sharing.
• Comfortable working as a generalist delivering projects across other capabilities when necessary.

Requirements:

• Hold a high standard of output. You are innovative, empathetic, a strong communicator with a great work ethic.
• Support more senior members of the team from day one, working independently and as an integral part of a team providing guidance and insight.
• Provide leadership to newer team members, willing to listen to new suggestions and ideas.
• Hold and develop great stakeholder management skills, building your reputation, client rapport and relationships.
• Professional and calm, translating complex client problems into actionable plans.
• Strong track record of delivering strategic cyber engagements for clients, such as cyber strategy & maturity assessments, target operating model design, regulatory readiness (e.g. DORA, NIS2, GDPR), cyber risk management & governance, and board-level cyber advisory.
• Relevant certifications (e.g. CISSP, CISM, CRISC, ISO 27001) are a plus but not essential.
• Excellent strategic and general consulting experience.
• Identify and seize opportunities. Creative and proactive, always looking at what we can do next.

• Client diversity: Work across industries and with ambitious businesses – from FTSE 100 to high-growth scale-ups.
