WHAT YOU'LL BE DOING
As a Senior Security Engineer in Purple Teaming, you'll plan and execute purple team exercises aligned to real‑world threat actors to protect Trade Republic's critical systems and customer data. Your responsibilities include:
• Design attack scenarios covering initial access, persistence, lateral movement, privilege escalation, command‑and‑control, and exfiltration.
• Coordinate with business and engineering teams to gather requirements, understand operational constraints, and ensure testing activities align with business risk.
• Assess existing security controls to ensure they aren't just "active," but actually effective.
• Conduct deep-dive assessments of internal networks, applications, and cloud infrastructure.
• Develop and tune SIEM detections, analytics rules, and alerts based on attack simulations and real incidents together with the Security Operations team.
• Validate alert quality, reduce false positives, and improve signal‑to‑noise ratio.
• Validate coverage of detections against known TTPs and identify detection gaps.
• Support and enhance incident response playbooks, escalation paths, and response automation.
• Conduct hypothesis‑driven threat hunts based on attacker tradecraft and threat intelligence.
