BAE Systems Digital Intelligence is home to 4,500 digital, cyber and intelligence experts. We work collaboratively across 10 countries to collect, connect and understand complex data, so that governments, nation states, armed forces and commercial businesses can unlock digital advantage in the most demanding environments.

Are you passionate about cutting-edge AI and machine learning in digital services, and want to deliver positive real-world value to the UK? We are looking for a Senior Security Consultant to join our team and help solve a variety of interesting problems in the national security space.

At BAE Systems Digital Intelligence, we work with a wide range of government customers, across defence, space, and government. In our national security AI team, we undertake a variety of projects covering exploratory research into AI methods and approaches, bespoke solutions to complex customer problems, and infrastructure projects working across large customer datasets.

We’re looking for a Security Consultant with deep knowledge of cyber security and practical expertise in AI/ML system security. You will help clients understand and mitigate AI-driven threats, secure modern cloud environments, and design architectures that remain resilient as AI capabilities evolve. You’ll work across strategy, architecture, and hands-on technical analysis to deliver secure solutions for high-impact, complex client environments.

This is an exciting time to join our team to help pioneer both our customer's and our own AI adoption journey. Not only will you be directly making a huge impact through the solutions you develop, you’ll be doing it for an organisation who makes a huge impact to the security of the UK.

• Conduct security assessments, threat modelling, and risk analysis across cloud, on-premises, and hybrid environments.
• Evaluate and secure AI/ML systems, including model governance, data pipelines, and model deployment patterns.
• Advise clients on AI risk management, including prompt injection, model poisoning, data leakage, privacy risks, and adversarial attacks.
• Design and recommend secure architectures for AI-enabled applications, including LLM-based systems, automation workflows, and decision-support platforms.
• Develop and maintain security policies, standards, and guidelines - particularly around AI governance and responsible AI use.
• Collaborate with engineering teams to implement secure configurations, guardrails, and controls.
• Stay ahead of emerging threats, technologies, and best practices in cybersecurity and AI safety.

You will have experience in many of the following:

• Proven experience in cybersecurity consulting, architecture, or engineering roles.
• Strong understanding of security fundamentals: identity & access management, network security, encryption, vulnerability management, and incident response.
• Hands-on experience securing AI/ML systems, LLMs, or data science pipelines.
• Knowledge of modern attack techniques including AI-assisted attacks, adversarial ML, and supply-chain risks.
• Familiarity with cloud security frameworks (AWS, Azure, GCP) and industry standards (NIST, ISO 27001, OWASP, MITRE ATLAS).
• Ability to translate complex technical concepts into clear guidance for both technical and non-technical stakeholders.
• Excellent report writing, communication, and client-facing skills.

• Certifications such as CISSP, CCSP, OSCP, CEH, GIAC, or cloud security certifications.
• Experience with AI model evaluation, fine-tuning, RAG pipelines, and vector databases.
• Understanding of AI ethics, governance, and regulatory frameworks (EU AI Act, NIST AI RMF, ISO/IEC 42001).
• Familiarity with DevSecOps, automation, IaC, and security control integrations.

Security Clearance is required for this vacancy. If you are not currently Security Cleared, you will need to be eligible for this and willing to go through the process.

• Work-life balance is important; you can work around core hours with flexible and part-time working.
• As many of our customers work predominantly in the office, we expect all of our staff to work at least 3 days per week in the office.
• You’ll get 25 days holiday a year and the option to buy/sell and carry over from the year before.
• Our flexible benefits package includes private medical and dental insurance, a competitive pension scheme, cycle to work scheme, taste cards and more.
• You’ll have a dedicated Career Manager to help you develop your career and guide you on your journey through BAE.
• You’ll be part of our company bonus scheme.
• You are welcome to join any/all of our Diversity and Support groups.

Our people are what differentiates us; they are resourceful, innovative and dedicated. We have a mix of generalists and specialists and recognise that this diversity contributes to our success. We recognise the benefits of forming teams from a mix of disciplines, which allows us to come up with cutting-edge, high-quality solutions.

You’ll be part of a big company, but we try to create a culture that feels like a small one. The work will stretch you and be challenging, but we encourage a healthy work-life balance. Most of all, we know teams who work well together also perform well. We’ll do everything we can to ensure you have fun at work, and in social activities outside of it whether that’s virtually or in person, as conditions allow.

You will be joining our National Security business which is the largest area within our UK business. Our mission is to be the most trusted partner for our National Security clients in delivery of their core mission.

You will work for a division of BAE Systems who helps nations, governments and businesses around the world defend themselves against cyber crime, reduce their risk in the connected world, comply with regulation, and transform their operations. We’re a consultancy and products business and employ smart, motivated individuals who work together across a range of projects and products.

We’re passionate about Diversity and Inclusion in our workforce and the people you’ll work with will reflect this. We employ over 4,000 people across 18 countries in the Americas, APAC, UK and EMEA.

We are embracing Hybrid Working. This means you and your colleagues may be working in different locations, such as from home, another BAE Systems office or client site, some or all of the time, and work might be going on at different times of the day. By embracing technology, we can interact, collaborate and create together, even when we’re working remotely from one another.

Diversity and inclusion are integral to the success of BAE Systems Digital Intelligence. We are proud to have an organisational culture where employees with varying perspectives, skills, life experiences and backgrounds – the best and brightest minds – can work together to achieve excellence and realise individual and organisational potential.
