Senior Platform Enterprise Architect
A UK enterprise is building a production-grade GCP platform for multi-agent AI. We are looking for a senior Platform Enterprise Architect to own the High-Level Design and technical roadmap for the underlying orchestration, governance, security, and delivery platform.
This is an immediate three-month contract with the possibility of extension. The role is hybrid in the UK, with domestic travel approximately once or twice every two months. Fluent English is required.
The Assignment
- Own and maintain the High-Level Design for a converged enterprise platform spanning predictive and agentic AI.
- Define the roadmap from isolated greenfield components into a unified, production-grade GCP stack.
- Architect a managed agent runtime covering orchestration, observability, evaluation, and operational controls.
- Create reusable golden templates for GCP agentic services, including ADK, Agent Engine, A2A, MCP, and related platform capabilities.
- Establish a central agent and tool registry to support discovery, reuse, and governance across domains.
- Define FinOps, telemetry, and operational standards across agentic use cases.
- Build security controls for agent memory, non-human identities, reasoning safeguards, and agent-to-agent communication.
- Apply Model Armor, VPC Service Controls, CMEK, mTLS, and Responsible AI controls.
- Embed security and privacy guardrails into Terraform and Google Cloud Deploy pipelines.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What We Need to See

- Hands-on mastery of Terraform and managed CI/CD, ideally Google Cloud Deploy.
- Enterprise security architecture covering identity, mTLS, network controls, encryption, and Responsible AI.
- Evidence of moving AI platforms from isolated prototypes or greenfield components into governed production services.
- Senior stakeholder leadership across platform engineering, security, privacy, and domain teams.
