Your impact 

Are you a network, systems, cloud or software engineer looking to take the next step into cyber security consultancy? 
Do you enjoy solving complex technical problems, working with customers, and influencing how systems are designed - not just built? 

Leonardo UK is looking for a Cyber Security Architect to join our Cyber & Security Solutions Division. This role is ideal for experienced IT professionals who want to broaden their impact, move into a consultative role, and help shape secure solutions for some of the UK’s most critical and complex environments. 

What you’ll be doing: 

As a Cyber Security Architect, you’ll work at the design and decision-making layer of major programmes. Rather than focusing on day-to-day operations, you’ll help customers build security in from the start - translating technical realities and business objectives into clear, robust, and proportionate security architectures. 

You’ll work in a collaborative, agile consultancy environment, blending home and on-site working, and engaging closely with customers, delivery teams and fellow specialists. 

Your role in practice: 

You’ll use your technical background to: 

Work with customers 

• Build trusted relationships and understand customer missions, constraints and operating environments 

• Engage confidently with engineers, project managers, security professionals and senior stakeholders 

Understand complex systems 

• Analyse existing and proposed IT environments, even where information is incomplete 

• Apply recognised security principles, architectural patterns and frameworks to real-world systems 

Think in terms of risk 

• Identify architectural risks, threats and vulnerabilities 

• Explain security trade-offs in clear, business-relevant language rather than just technical detail 

Design secure solutions 

• Define layered, secure by design architectures across people, process and technology 

• Recommend practical security controls and patterns that will support project delivery 

Provide assurance 

• Review designs and implementations against agreed standards and regulatory expectations 

• Support architecture governance, compliance and security assurance activities 

Grow the practice 

• Contribute to reusable architectural patterns, frameworks and offerings 

• Provide technical leadership in bids, proposals and early solution shaping 

What you’ll bring 

This role suits experienced engineers or consultants who are comfortable with complex systems and are ready to step into a broader, more influential security role. 

Core strengths 

• Strong communication and stakeholder engagement skills 

• Ability to explain complex technical concepts clearly and confidently 

• A consulting mindset: adaptable, dependable and focused on high-quality outcomes 

• Enjoy working collaboratively and supporting the development of others 

Technical background 

• Solid understanding of core IT fundamentals such as TCP/IP, networking, protocols and system interactions 

• Experience designing or supporting complex IT, cloud, application or networked systems 

• Ability to decompose large systems into logical, secure architectural components 

Security and architecture 

• Experience translating high-level functional or mission objectives into technical or security requirements 

• Understanding of security controls, threat mitigation and architectural trade-offs 

• Ability to justify why a control or design decision is needed — to both technical and non-technical audiences 

Additional experience (beneficial, not essential) 

• Previous exposure to security architecture, risk assessment or design assurance 

• Experience mentoring junior engineers, architects or consultants 

• Familiarity with UK MOD, defence or national security environments 

Certifications 

We value practical experience, but relevant certifications are welcomed, such as: 

• Security+: CISMP, CCSP 

• TOGAF 

• AWS or Azure cloud certifications 

This is not an exhaustive list, and we are keen to hear from you even if you might not have experience in all the above. The most important skill is a good attitude and willingness to learn.  

Security Clearance 

This role is subject to pre-employment screening in line with the UK Government’s Baseline Personnel Security Standard (BPSS). An additional range of Personnel Security Controls referred to as National Security Vetting (NSV) may apply, this could include meeting the eligibility requirements for The Security Check (SC) or Developed Vetting (DV). For more information and guidance please visit: https://careers.uk.leonardo.com/gb/en/security-and-vetting
