Application Security Specialist

The Application Security Specialist exists to embed application security expertise across Europe’s products and services, supporting the Secure Development Practice and enabling a consistent ‘shift-left’ approach. The role is accountable for advancing application security capability, leading security reviews on higher-risk systems, and ensuring secure development practices are adopted across engineering teams. The post holder will act as a technical authority on application security, helping reduce vulnerability risk and improve security outcomes across both internal IT systems and customer-facing solutions.

Application security capability development (CoE contribution)

• Contribute to establishing and operating a pan-European application security capability within the Secure Development CoE.
• Build and maintain a network of application security practitioners across development teams.
• Develop an understanding of current application security maturity, tooling and practices across Europe.
• Define and promote consistent application security methodologies, patterns and practices.
• Contribute to CoE forums, standards discussions and knowledge sharing across teams.

Application security reviews and assurance

• Lead application security reviews for high-risk products and services.
• Coordinate with Product Security Development Specialists to define scope, coverage and prioritisation.
• Conduct and oversee:
• static application security testing (SAST)
• dynamic testing (DAST)
• fuzz testing where appropriate
• API and interface security reviews
• architecture and design-level assessments
• assessment against OWASP Top 10 and other relevant standards
• Interpret findings and translate them into actionable remediation plans.

Secure development standards and guidance

• Support the development and maintenance of secure coding standards across key languages such as C, C++, Java and other relevant stacks.
• Contribute to application security policies and supporting technical documentation.
• Provide practical guidance to developers on secure coding and remediation approaches.
• Align standards with recognised frameworks such as OWASP and relevant secure development frameworks.

Developer enablement and training

• Deliver and coordinate application security training for development teams.
• Introduce internal or external specialised training content.
• Support secure coding awareness, hands‑on workshops and threat-focused learning.
• Act as a point of contact for development teams needing security guidance.

Security culture and shift-left adoption

• Promote a security‑first mindset within engineering and product teams.
• Embed security considerations into design, development and deployment processes.
• Support early‑stage security engagement in development lifecycles.
• Champion pragmatic and developer‑friendly security practices.

Threat and vulnerability management (product focus)

• Support the threat and vulnerability management process across product and service lines.
• Assist in triaging, prioritising and managing application‑level vulnerabilities.
• Provide technical input into remediation planning and risk decisions.
• Identify recurring issues and systemic weaknesses in development practices.

CI/CD security integration and tooling

• Design and support secure CI/CD pipeline patterns.
• Identify, evaluate and help implement appropriate security tooling across development pipelines.
• Integrate SAST, DAST, SCA and other application security tools into build and release processes.
• Support automation of security controls and checks within development workflows.
• Contribute to the development of secure practices for AI‑enabled applications.
• Support emerging controls and patterns related to AI model security, data handling and misuse risks.
• Assist teams in embedding security into AI and data‑driven development processes.
• Monitor application security trends, vulnerabilities and emerging threats.
• Recommend improvements to processes, tooling and developer practices.
• Contribute to maturity improvement of the Secure Development Practice.

Task level

• Conducting application security scans and manual reviews
• Supporting remediation of vulnerabilities
• Producing technical findings and guidance
• Delivering training and guidance sessions

Process and policy level

• Designing and embedding application security processes in SDLC
• Developing secure coding standards and review frameworks
• Implementing security controls into CI/CD pipelines

Theoretical and cross‑disciplinary level

• Applying secure development frameworks such as SSDF
• Understanding application, infrastructure and data security interactions
• Translating security theory into practical secure development practices
• Operating across software engineering, cyber security and risk domains

Technical Skills required

• Strong knowledge of application security principles and practices
• Experience with SAST, DAST and software composition analysis tools
• Knowledge of secure coding practices across languages such as Java, C, C++
• Experience with CI/CD pipelines and DevSecOps integration
• Threat modelling techniques and tools
• Understanding of OWASP Top 10 and common vulnerability classes
• Experience with API security and web application security
• Understanding of fuzz testing and advanced testing techniques
• Familiarity with secure AI development considerations
