On behalf of our client, a general financial services enterprise running a large-scale, highly regulated cloud data platform - we're looking for a Lead Security Architect to own the security of their Oracle (OCI) and PostgreSQL database landscape.

Why this role is different
Most security architect roles hand you the rules and expect someone else to build the control. Most DBA/security-engineering roles hand you a ticket and expect someone else to have already decided what "secure" means. This role is neither.

You will own the full chain: understand what EU regulation (DORA, BaFin, GDPR, and internal group security standards) actually requires, translate that into concrete architecture for the cloud database estate, and then get hands-on with the implementation yourself. You'll also be the person who sits across the table from auditors and regulators and can explain, in plain language, why the architecture is built the way it is and you'll lead a small squad of engineers who help you deliver it.

Our client is entirely cloud-native, working in Kanban,



as a pure delivery team fully decoupled from line management - you organize and prioritize the work.

What you'll own
End-to-end secure architecture for

Oracle Database on OCI

and

PostgreSQL : encryption, key management, hardening, and secure-by-design patterns.
Zero Trust network security

for cloud database environments - private endpoints, segmentation, certificate lifecycle management.
Threat modelling that turns into real engineering controls, not slide decks.
Identity and access

integration with Microsoft Entra ID, OAuth/OIDC, Conditional Access, Privileged Identity Management for database access.
Vulnerability management and DevSecOps practices across the platform.
Being the

primary point of contact for security audits and annual pentests
- prepping, guiding, and converting findings into remediation.
Leading and mentoring a

3-person security engineering squad
- priorities, incidents, stakeholder communicat
