Lead Security Engineer | £77,000 + Benefits | Hybrid - x1 day per Week onsite (London)
Here at Burns Sheehan, we are working with a growing international business as they look for a Lead Security Engineer to join a small but highly visible security function. This is a hands-on engineering role focused on building and improving security controls across a complex IT estate, rather than sitting purely in monitoring or governance.
The environment is evolving, so this would suit someone comfortable working in a business where not everything is fully mature yet. There’s a strong focus on practical delivery, improving visibility, reducing risk, and implementing controls that genuinely improve day-to-day security operations.
You’ll work closely with infrastructure, engineering, and operational teams, helping shape the security roadmap while remaining technically involved.
What you’ll be doing:
* Designing and implementing security controls across infrastructure, identity, endpoint, network, and SaaS environments
* Leading initiatives around asset visibility, application discovery, and ownership tracking
* Driving zero trust and identity-aware access controls
* Improving identity lifecycle management and access governance
* Working with SIEM, EDR, and vulnerability tooling to improve detection quality and reduce alert noise
What they’re looking for:
* Strong infrastructure or networking background with progression into security engineering
* Hands-on experience implementing Zero Trust, SSO, IAM, and security controls from scratch
* Experience with Entra ID, SIEM/EDR platforms, vulnerability management, and asset visibility programmes
* Good understanding of Microsoft environments, endpoint security, and SaaS-heavy estates
* Comfortable operating autonomously in a lean, fast-moving environment where priorities evolve quickly
Sound Interesting? Feel free to Apply and I look forward to your applicaiton !!!
