Senior Red Team Engineer - UK remote - £70,000 - £90,000

Join an elite internal Red Team within one of the most innovative financial services organizations in the UK.

You’ll be part of a mission critical team that operates like a stealth unit, delivering high impact engagements that shape the security posture of a global financial powerhouse.

Why This Role is Exciting

• Work on advanced adversary emulation, leveraging the latest TTPs (Tactics, Techniques, and Procedures) from real world threat actors.
• Your work directly influences the security of millions of customers and the integrity of financial systems.
• Collaborate with world‑class security professionals and leverage state of the art tools and frameworks.
• Design and execute bespoke attack scenarios, from phishing campaigns to complex lateral movement strategies.
• Operate from anywhere in the UK while being part of a dynamic, forward thinking team.

Key Responsibilities

• Plan and execute full scope Red Team engagements simulating advanced persistent threats.
• Develop and refine attack methodologies aligned with MITRE ATT&CK and emerging threat intelligence.
• Collaborate with Blue Teams to validate detection and response capabilities.
• Produce detailed reports and deliver executive-level briefings on findings and recommendations.
• Continuously research and integrate new offensive security techniques and tools.

What We’re Looking For

• Proven experience in Red Teaming, penetration testing, or offensive security operations.
• Deep understanding of adversary tactics, lateral movement, privilege escalation, and evasion techniques.
• Strong knowledge of Windows, Linux, and cloud environments.
• Familiarity with frameworks such as MITRE ATT&CK, NIST, and OSSTMM.
• Excellent communication skills and ability to translate technical findings into business impact.
