The role
Major financial institutions still run on manual, complex analysis. This company builds AI systems that automate those workflows, transforming how global banks, private equity, and credit firms operate on their most sensitive data. They're one of the fastest-growing enterprise AI platforms, backed by significant funding from leading investors.
This is the first platform leadership hire, owning the end-to-end cloud strategy and building the platform team from the ground up. You'll define the standards for reliability, security, and compliance that directly enable the product, rather than inheriting them from a legacy system. This isn't a role about maintaining existing infrastructure; it's about architecting and scaling a greenfield Azure/AKS environment with the mandate and funding to do it properly.
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 You Bring
- 10+ years in infrastructure or platform engineering, including architecting and operating production-grade Kubernetes and Terraform environments at scale.

- Proven track record implementing reliability, security, and compliance measures, navigating frameworks like SOC 2, ISO 27001, or GDPR.
