They collaborate with stakeholders, including the relevant enterprise architect, to ensure design decisions align with strategic direction. Security Design Engineers present and share solutions at design authorities and senior leadership meetings, providing technical thought leadership and direction to aligned projects. They may act as subject‑matter experts and consultants related to programmes. This position sits between an Application Architect and Security consultant, with a focus on Application Architecture. It is a contract role up until November with potential extension, based in either Edinburgh or Sheffield with three days a week required in office.

- Knowledge of SCA tools and methodologies (e.g., dependency analysis, open‑source license compliance, vulnerability triage, supply‑chain risk management).
- Deep experience implementing and optimising AST capabilities, including SAST, DAST, IAST, MAST and container/K8s security scanning.
- Demonstrated success designing and integrating security testing pipelines within CI/CD environments (GitHub Actions, GitLab, Jenkins, Azure DevOps, etc.).
- Strong background in threat modelling, secure SDLC design, and establishing risk‑based security policies for code, dependencies, and build systems.
- Ability to evaluate, select, and architect AppSec technologies, including enterprise SCA/AST platforms, SBOM solutions, and vulnerability management workflows.
- Experience collaborating with engineering teams to prioritise and remediate vulnerabilities, provide secure coding guidance, and enable developer‑centric security practices.
- Familiarity with industry frameworks and standards (OWASP SAMM, ASVS, CSA, NIST SSDF, supply‑chain security frameworks such as SLSA).
