Your expertise in handling complex security systems and incidents will contribute to the defence and resilience of key national infrastructure.


The Senior Engineer will operate at both the OS and S security tiers, with a focus on incident response, detection, and analysis of security events.

  • Security Alert Analysis : Identify and investigate network security alerts from various enterprise sources, determining the causes of anomalies and potential threats.
  • Intrusion Detection and Prevention : Detect, monitor, and analyse network traffic for signs of intrusions or attacks, using IDS/IPS systems.
  • Advanced Threat Hunting : Proactively conduct research and analysis on potential cyber threats, correlating data across multiple platforms to identify trends and vulnerabilities.
  • Log File Analysis : Perform detailed analysis of log files from various sources (host, network traffic, IDS, firewalls) to identify malicious activities or system anomalies.
  • Incident Triage & Resolution : Prioritize and manage security incidents by determining the severity, scope, and impact, and recommending timely remediation strategies.
  • Security Trends & Reporting : Produce detailed reports on emerging threats, trends, and incidents, providing valuable insights for continuous improvement in cyber defence capabilities.
  • Network Security Engineering : Apply your technical skills to troubleshoot, configure, and enhance the overall security posture of MoD’s IT infrastructure.
  • Technical Leadership : Provide expert guidance to junior engineers and SOC analysts, ensuring best practices in cyber defence are applied across the team.


Your Profile

To succeed in this role, you should bring extensive technical knowledge and practical experience in cyber security engineering. We are seeking someone with strong problem-solving capabilities, a strategic mindset, and the ability to lead complex projects with minimal supervision.


Key Requirements :

  • Cyber Defence Expertise : Deep knowledge of cyber security principles, technologies, and operations, with experience in securing large-scale enterprise environments.
  • Incident Response & Management : Proven track record in managing and resolving high-priority cyber incidents, including detection, triage, and remediation.

  • Leadership : Ability to lead teams and projects, mentor junior engineers, and translate complex technical issues for senior leadership.
  • Operational Experience : Experience working in SOC environments or handling cyber incidents in a military, government, or critical national infrastructure setting.
  • Decision-Making : Capable of making sound decisions quickly, with minimal reference to the chain of command.
