Cyber Security Analyst, DevSecOps in Hounslow

The Cyber Security Analyst – Secure Development is responsible for embedding secure-by-design and security-by-default principles across Heathrow’s entire software development lifecycle (SDLC). Working as part of the Cyber Security Team and reporting to the Lead Architect, Cyber Applications & AI, the role provides expert security advisory, assessment and automation capabilities to ensure security is built into code and development processes from inception rather than treated as a follow-on activity. The role plays a key part in fostering a collaborative DevSecOps culture, enabling development teams to deliver high-quality, secure software while maintaining pace and innovation in a complex, safety- and security-critical environment.

Responsibilities

• Secure Development & SDLC Integration: Embed secure development practices across all stages of the SDLC, from design and build through to deployment and maintenance. Ensure security requirements, patterns and controls are incorporated early into application and platform design. Promote and enable secure-by-design and security-by-default principles across the development community.
• Advisory & Assessment: Provide hands-on security advisory support to software engineering teams, architects and product owners. Conduct security design reviews, code assessments and threat modelling activities. Assess development pipelines, tooling and environments to identify security weaknesses and improvement opportunities.
• Monitoring & Detection: Monitor development environments, repositories and pipelines for poor security practices, exposed secrets, credentials and misconfigurations. Support the identification, triage and remediation of security findings in collaboration with development teams.
• Security Automation & Tooling: Design, implement and maintain automated security checks within CI/CD pipelines, including static, dynamic and dependency scanning. Enable consistent and scalable security controls through automation, reducing manual overhead and improving developer experience. Work with platform and tooling teams to integrate security capabilities into development ecosystems.
• Collaboration & Culture: Foster a collaborative, trust-based relationship between the Cyber Security team and the development community. Act as a security champion, influencing ways of working and promoting security awareness and ownership within engineering teams. Build strong working relationships with internal and external colleagues, partners and suppliers.
• Continuous Improvement: Stay current with emerging threats, secure coding techniques and DevSecOps best practices. Contribute to the evolution of secure development standards, patterns and guidance. Support continuous improvement of Heathrow’s application security maturity.

Qualifications

• Experience: Minimum 3 years’ relevant technical experience in Cyber Security, application security, secure development or DevSecOps. Practical experience working within software development environments and modern SDLC practices. Proven experience working collaboratively within multi-disciplinary teams.
• Essential Skills: Strong understanding of application security principles and common vulnerabilities (e.g., OWASP Top 10). Experience embedding security into SDLC and CI/CD pipelines. Ability to assess code, architectures and development practices from a security perspective. Familiarity with security tooling such as SAST, DAST, dependency scanning and secrets detection. Strong stakeholder engagement and relationship-building skills. Ability to communicate security concepts clearly and pragmatically to technical and non-technical audiences. Collaborative mindset with a focus on enablement rather than control.
