Principal Backend Engineer

Security Operations

• Investigating security events. You'll work alongside our senior team members to navigate incidents across our network, endpoints, and cloud systems. You'll play an active role from the initial alert through to recovery, and as you build your skills and confidence, we will support you to lead these responses.
• Proactively hunting for threats. You test theories about how attackers might target us and search for hidden threats across our systems before they trigger alerts.
• Spotting real threats. You fine-tune our alerts so we only spend time looking at genuine risks. You use these alerts to drive your incident response investigations, focusing your energy on stopping attackers.
• Automating repetitive work. You build automations that handle routine tasks, giving the squad time to focus on complex, analytical challenges.
• Learning from past incidents. You run blameless reviews after incidents to find the root cause, using those lessons to improve our security controls across the business.
• Tracking threat intelligence. You research the attackers that pose a risk to us and turn that knowledge into active, automated defences.
