Cyber Security Consultant

About Elixirr

Elixirr International plc is a global consulting firm with a bold ambition: to become the best consulting firm in the world.

Founded in 2009 to challenge a declining industry standard, 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. In that time, our market cap has grown from £98 million to over £350 million – a testament to our differentiated approach and relentless pursuit of excellence.

With a presence across the UK, US, EU, and South Africa, and a client base spanning industries and geographies, we’ve welcomed seven boutique firms into the Group. This has broadened our capabilities across creative, digital marketing, data and AI, procurement, transformation, and more.

Our vision of becoming a services unicorn is firmly within reach – and this is just the beginning. 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. It’s where it all began for us and continues to be a hub of innovation and growth. Our east coast hub is based in New York City. We’re proud of the work we’ve done here to help clients disrupt their industries

Job Summary

We are seeking a client-facing Cyber Security Consultant to lead and deliver client engagements across a range of industries. This role is ideal for someone with deep consulting experience in cyber security and a strong understanding of how organisations can build resilience, manage cyber risk, and align security with broader business objectives.

You will operate at the intersection of strategy and cyber risk, supporting C-suite clients in making informed, strategic decisions in an increasingly complex digital environment.

Responsibilities

• Lead 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

• Minimum 2-4 years’ experience in client-facing consulting roles, ideally within a top-tier or boutique consultancy with a focus on cyber security

• 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

• Board-level cyber advisory

• Excellent strategic and general consulting experience

• Strong communication skills with the ability to influence senior stakeholders and simplify complex concepts

• Commercial mindset, entrepreneurial energy, and a collaborative approach

• Relevant certifications (e.g. CISSP, CISM, CRISC, ISO 27001) are a plus but not essential

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