The title sounds abstract, but the job has a concrete output: a design that states which assets matter, how they could be attacked, and which controls stop that from happening. Everything else supports that document.

Translating risk into structure

Business leaders describe risk in terms of revenue, contracts and reputation. Engineers describe it in ports, protocols and permissions. The architect sits between them and produces a design that both groups can read and agree on.

Deciding, not just advising

An architect who only offers opinions is a consultant. The role carries authority to say a design is not acceptable, and responsibility to propose one that is. Learning to make and defend those decisions is most of the growth curve.

Where the role sits in delivery

Architecture happens before code is written and again whenever a system changes materially. You are involved at concept, at design review, and at any major change, but you are rarely the one implementing.

Action step

Write one paragraph describing a system you know well: what it protects, who would want to attack it, and the three controls that matter most. This is your first architecture statement.
