Lead / Staff Security Engineer

Lead / Staff Security Engineer

London | Hybrid – 3 days

We’re working with a scaling technology company building modern infrastructure products used by engineering teams operating in highly sensitive and high-trust environments.

The business sits in a genuinely interesting space between developer tooling, cloud infrastructure and secure systems, with a strong engineering culture and a big focus on building products properly from the ground up.

They’re now looking to hire a senior security leader to help shape and scale security engineering across the organisation as the platform and customer footprint continue to grow.

The Role

This is not a governance-heavy or purely compliance-focused security position. The role sits very closely with engineering, infrastructure and product teams, helping embed security into the core of how systems are designed and built.

Responsibilities will include:

• Driving the overall security engineering strategy.
• Partnering with software and infrastructure teams on secure architecture and engineering practices.
• Improving detection, monitoring and incident response capabilities.
• Building scalable approaches around cloud security, automation and internal tooling.
• Helping mature security processes in a fast-moving engineering environment.
• Acting as a senior technical voice internally across security best practices and risk management.

What They’re Looking For:

They’re open-minded on background, but they’ll likely be interested in people who have:

• Strong hands-on security engineering experience.
• Experience operating within modern cloud-native environments.
• Knowledge across infrastructure, application and cloud security.
• A strong engineering mindset with an interest in automation and tooling.
• Experience working in fast-paced product or platform-led technology businesses.
• The ability to balance technical depth with leadership and communication.

Environment:

You’d be joining a collaborative, engineering-led team working on technically complex systems where security is seen as a core product and engineering function rather than a separate department.

The company is still at a size where you can have genuine influence, ownership and visibility whilst working on problems around scale, infrastructure and secure systems design.
