Lead/Senior Cybersecurity Operations Specialist (Security Services)

The client is a leading agency driving their clients' initiatives and public sector digital transformation. As the Centre of Excellence for Infocomm Technology and Smart Systems (ICT & SS), the client develops capabilities in Data Science & Artificial Intelligence, Application Development, Smart City Technology, Digital Infrastructure, and Cybersecurity.

The Cyber Security Group is the cybersecurity arm of our client, committed to creating a digital government that is safe and secure. CSG delivers technical and operational capabilities to counteract cyber threats, provides thought leadership on transformative cybersecurity governance and policies, and strengthens the cybersecurity posture of government agencies sustainably and effectively.

As the Security Services Specialist within the firm, you will be the domain expert responsible for elevating the security testing and "Secure-by-Design" capabilities across the entire firm. You will bridge the gap between high-level governance and technical implementation, ensuring that all agencies under the firm’s purview adopt consistent, high-quality security practices. Your role is pivotal in shifting the firm from a reactive security posture to a proactive, resilient one.

• Security Testing Governance & Standardisation
  • Establish Standards: Define and maintain the Ministry-wide framework for security testing (Vulnerability Assessment and Penetration Testing - VAPT).
  • SOP Development: Create and roll out Standard Operating Procedures (SOPs) to guide Agency project teams on engaging external security vendors and managing internal testing cycles.
  • Quality Assurance: Develop "Quality Rubrics" to help agencies evaluate the performance of pen-testers.
• Advanced Technical Operations
  • Red Teaming & Critical Testing: Lead and execute complex Red Teaming exercises and deep-dive penetration tests on the client’s high-impact systems.
  • Adversary Simulation: Utilise knowledge of the latest Adversary Tactics, Techniques, and Procedures (TTPs) to simulate real-world attacks, helping agencies identify blind spots in their prevention, detection, and response capabilities.
  • Environmental Scanning: Proactively monitor the global threat landscape to identify emerging threats and evolving actor TTPs.
• Secure-by-Design & Source Code Excellence
  • Secure Coding Standards: Establish Ministry-wide secure coding guidelines (e.g., based on OWASP, SANS) to ensure developers build security into the application layer from day one.
  • Source Code Analysis: Lead the strategy for Static Application Security Testing (SAST) and Software Composition Analysis (SCA).
  • CI/CD Integration: Evaluate, recommend, and provide guidance on integrating security tools into the agencies' DevOps pipelines (DevSecOps).
  • Code Quality Oversight: Review and recommend systems that help to boost code quality, ensuring that security is treated as a core component of "clean code."
  • Technology Foresight: Stay abreast of technology changes (e.g., Cloud-native security, AI-driven development) and recommend systems/technologies that enhance code quality and resilience.
• Stakeholder Engagement & Advocacy
  • Consultative Leadership: Act as a trusted advisor to Agency CIOs, ACISOs, and Project Owners to educate them and inculcate a culture of secure-by-design.
  • Community of Practice: Establish a platform for knowledge sharing among security practitioners within the firm to harmonise security testing efforts.

• Years of Experience: 8 to 10 years of deep technical experience in Cybersecurity, with a strong focus on offensive security and application security.
• Domain Expertise: Proven track record in conducting penetration tests for Web Applications, IT Systems (on-premises and cloud environments), and complex Network architectures.
• Code Review Mastery: Experience in performing manual and automated source code reviews to identify logic flaws, injection vulnerabilities, and cryptographic weaknesses.

• Secure Development: Deep understanding of secure software development lifecycles (SSDLC) and the ability to read/analyse common programming languages (e.g., Java, Python, .NET, JavaScript).
• Source Code Analysis Tools: Proficiency with enterprise-grade SAST, DAST, SCA, and VAPT tools (e.g., Checkmarx, Fortify, SonarQube, Snyk, Burp Suite).
• Offensive Security: Proficiency in manual and automated testing tools; deep understanding of the MITRE ATT&CK framework and common TTPs.
• Cloud & DevOps: Experience with Government Commercial Cloud (GCC) environments and practical knowledge of Jenkins, GitLab CI, or GitHub Actions.
• Certifications: Professional certifications such as OSCP, OSWE (Offensive Security Web Expert), CASE (Certified Application Security Engineer), or GWEB are highly desirable.

• Influence & Diplomacy: Ability to communicate complex technical risks to non-technical stakeholders (CIOs/Project Owners) and influence change without direct reporting lines.
• Analytical Mindset: Ability to spot patterns in "bad" testing jobs or recurring code vulnerabilities and provide constructive feedback to improve agency-level performance.
• Intellectual Curiosity: A strong commitment to continuous learning and keeping pace with the rapidly evolving cyber threat landscape.
