Cloud Solution Architect
The Solution Architect ensures that teams deliver secure, domain-aligned, production-ready solutions by correctly applying and evolving domain, API, authentication, authorization, and platform building blocks. The role bridges standards and delivery by aligning teams, guiding correct usage, enabling roadmaps, and evolving building blocks where justified by real-world needs.

Your Impact as Cloud Solution Architect
What are you going to do

-
- Apply existing domain and API building blocks (DDD, REST, EDA, MCP) and ensure solutions align to defined bounded contexts and published contracts.
- Determine API fit-for-purpose by selecting appropriate existing APIs; identify, articulate,



and elevate gaps where required capabilities or standards are missing.
- Guide and evolve security architecture, with equal focus on: Authentication (AuthN): correct application and extension of documented identity and token flows (OIDC/OAuth2, client types, audiences, token lifetimes, trust models); Authorization (AuthZ): applying and extending the ReBAC model when solution needs exceed current capabilities, in alignment with security governance.
- Secure connectivity patterns including mTLS and certificate-based trust where required.
- Architect missing building blocks for emerging technologies (e.g., introducing MCP as a standard capability pattern), ensuring they are reusable, governed, and secure by design.
- Align across teams and domains (Design, Platform, Delivery): translate architectural gaps and cross-team dependencies into clear enablers.
- Ensure these enablers are prioritized and placed on the appropriate team roadmaps.
- Act as a synchro
