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

Key responsibilities include:

* 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 escalate 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 synchronizing role to prevent fragmentation and duplicate solutions.

* Define solution architecture aspects related to infrastr
