Senior Security Architecture Engineer: Threat Modelling

Wlgroup; Eigenbrakel; Hybride; EUR 90 000 - 130 000; Plein temps

Résumé du poste

Wlgroup in Belgium is looking for a senior security architect to own reference architectures, baselines and risk registers, with a hands-on approach to design review and incident handling.

You will lead threat modelling, align designs with secure-by-design patterns, and oversee deployment of server apps on Windows and Linux, plus cloud configurations in Azure and AWS. The role is hybrid, with on-site work in Braine-l'Alleud.

Qualifications

• Senior experience supporting commercial applications in a large, governed environment.
• Security architecture in practice — threat modelling, hardening, risk registers, architecture gates.
• Identity and access work: OAuth, OpenID Connect, SAML 2.0, and directory-backed identity in the cloud.
• Cloud configuration on Azure and AWS.
• Windows and Linux server application deployment, and administration of collaboration tooling.
• Strong customer relationship skills — much of the value here is in how the advice lands.

Responsabilités

• Define secure-by-design reference architectures, patterns and hardening baselines, and review new or changed service designs against them.
• Lead threat modelling for new and materially changed services, own the technical risk entries, and track mitigations to closure.
• Run proofs of concept and produce evidence-based recommendations covering cost, operational impact, lock-in and exit.
• Support deployment and operation of server applications on Windows and Linux, and integrate them with identity providers.
• Manage cloud configuration across Azure and AWS, including identity groups and roles.
• Support deployment, configuration and monitoring of AI-based tooling and its integration with existing applications.
• Handle complex third-line incidents, escalated to vendors where it is warranted, and build the knowledge base as you go.
