Job Description

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. 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.

Job Responsibility

  • 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

Requirements

  • 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
