You'll also oversee improvements across endpoint hardening, vulnerability management, IAM, cloud security and internal controls. Working with an outsourced SOC and MDR provider, you'll ensure security monitoring and escalation processes are effective, while helping progress initiatives such as SASE and SOC 2 compliance.

Alongside hands-on technical delivery, you'll work with stakeholders across the business, communicate risks and recommendations clearly and help improve security awareness through internal training. This is a senior individual contributor role where you'll have the freedom to identify problems, take ownership and deliver meaningful improvements.

About you:

• You're an experienced Cyber Security Engineer with a broad spectrum of knowledge
• You have experience within Financial Services with a good knowledge of governance, risk and compliance requirements
• You have deep networking and infrastructure security experience, including firewalls, secure networking and network layer controls
• You have a good knowledge of IAM, endpoint security, hardening and vulnerability management.
• You have an understanding of cloud security, with the ability to develop this further (they use GCP)
• You have experience of improving security controls, architecture and operational processes
• You're familiarity with outsourced SOC / MDR services, Zero Trust, SASE or SOC 2
• You have excellent communication skills, able to explain technical risks and recommendations to non-technical stakeholders
• You have a proactive, commercially aware approach, with the confidence to drive improvements independently
• You're degree educated in a STEM discipline

What's in it for you:

As a Lead Cyber Security Engineer you will earn a competitive salary (to £100k) plus pension and other benefits.
