You’ll be trusted to play your part in delivering the advanced, technology-led defence, aerospace and security solutions of tomorrow – shaping a safer future, for all of us.

Role Description:

Working within Cyber Operations, you will help safeguard BAE Systems against evolving cyber threats by supporting and enhancing the External Attack Surface Management (EASM) capability across people, process, and technology. You will contribute to an intelligence-led approach to cyber operations, ensuring external assets are identified, assessed, and continuously tested. The role supports detection assurance by identifying shadow IT and unmanaged exposures, providing confidence to leadership that security controls and monitoring capabilities are effective and aligned to organisational security standards.

Core Duties:

• Proactively discover, track, and maintain visibility of external attack surface assets, including unknown and shadow IT exposures
• Investigate and validate externally visible exposures, assessing real-world risk, attacker relevance, and exploitability
• Monitor changes in external exposure, identifying new assets, regressions, and emerging risks across the estate
• Collaborate with Threat Intelligence and Cyber Operations to align exposure findings with attacker activity and remediation priorities
• Produce clear, actionable reporting on external exposures, trends, and security posture to support risk reduction and decision-making

Essential Skills:

• Good understanding of external reconnaissance techniques, OSINT, and how attackers identify and profile internet-facing assets
• Proven experience in attack surface discovery, asset enumeration, and identifying unknown or shadow IT exposures
• Good investigative mindset with the ability to analyse incomplete or ambiguous external data and determine genuine security risk
• Ability to assess and distinguish between observed external artefacts, misconfigurations, and true exploitable exposures from an attacker’s perspective
• Experience working with internet-facing protocols and data sources (e.g. DNS, HTTP, TLS, certificate transparency, scanning datasets) to identify patterns, relationships, and anomalies

The Cyber Operations team:

Cyber Operations is responsible for protecting BAE Systems from Cyber Attack by various threat actors. Not only do we protect BAE Systems and its employees, indirectly we protect those who protect us – who serve in our military and rely on the products and services we create across Threat Intelligence, Detection, Incident Response and now Active Defence we work to evolve cyber operations as a world class capability.
