Cybersecurity Engineer (Cloud / Platform Security / Incident Response)

We are partnering with a leading public-sector technology organisation driving large-scale digital transformation initiatives across critical national systems.

This is an exciting opportunity for a cybersecurity professional to apply security engineering principles to real-world, high-impact platforms while working across cloud, platform engineering, and cyber defence domains.

You will work closely with product, platform, and security teams to strengthen the security posture of mission-critical systems through secure architecture implementation, operational security improvements, threat detection, and automation.

What You'll Be Doing:

Cybersecurity Operations

. ⁠Develop and maintain security reporting dashboards, leveraging automation to improve operational efficiency

. Review vulnerability assessment and penetration testing findings, validate risks, and support remediation planning

. Perform vulnerability validation across infrastructure, application, and platform environments

. Assist in refining incident response playbooks and operational procedures

. ⁠Support compliance activities, including evidence gathering and control documentation

. ⁠Implement and operationalise security controls across enterprise platforms

. ⁠Participate in threat modelling sessions and identify security requirements aligned with organisational policies

. Conduct periodic identity and access reviews to enforce least-privilege principles

Security Engineering & Architecture

. Apply security standards and controls across CI/CD pipelines, containerised platforms, and cloud-native environments

. ⁠Contribute to secure system design reviews and architecture assessments

. ⁠Strengthen platform security across Kubernetes and modern infrastructure environments

Cyber Defence & Incident Response

. Support incident response activities, investigation workflows, and escalation processes

. Perform alert triage across SIEM, EDR, and cloud security monitoring platforms

. ⁠Enhance detection logic, response workflows, and operational playbooks

. Participate in guided threat hunting to identify indicators of compromise and emerging threats

Product Security Engineering

. Build proof-of-concepts and deliver security-focused engineering enhancements

. ⁠Utilise code scanning, cloud security analysis, and security testing tools to identify and remediate vulnerabilities

. ⁠Recommend and implement improvements to enhance product security, scalability, and operational efficiency

Emerging Security Research

. Evaluate emerging cybersecurity tools and technologies through structured testing

. ⁠Contribute to proof-of-concept initiatives focused on strengthening engineering and security capabilities

Collaboration & Continuous Improvement

. Work closely with cross-functional engineering and security teams

. ⁠Share technical knowledge, lessons learned, and best practices

. ⁠Proactively identify opportunities to improve processes, tooling, and team effectiveness

Requirements:

. Degree in Cybersecurity, Computer Science, Computer Engineering, Information Technology, or related discipline

. ⁠Relevant cybersecurity experience or demonstrated technical capability through projects, internships, or hands-on work

. Any relevant certifications such as ⁠OSCP, ⁠CISSP or other relevant cybersecurity certifications will be highly regarded

What We're Looking For:

Technical Expertise

. Solid foundation in security architecture, secure system design, and threat modelling

. ⁠Experience validating vulnerabilities and supporting remediation efforts

. Familiarity with securing CI/CD pipelines, Kubernetes environments, and cloud platforms

. ⁠Exposure to developer-centric security tooling, automation frameworks, and AI-assisted engineering workflows

. Hands-on experience with SIEM, EDR, and cloud-native security monitoring tools

. ⁠Understanding of detection engineering, incident response processes, and threat hunting methodologies

. ⁠Scripting or automation skills using Python, Bash, or similar

. Good understanding of identity & access management (IAM), secrets management and zero trust security principles

What Makes You Successful

. Able to work independently and manage priorities effectively

. ⁠Strong problem-solving mindset with sound judgement on escalation paths

. Adaptable in fast-changing technical environments

. ⁠Collaborative, proactive, and solutions-oriented

. Passionate about continuous learning and security innovation
