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.
Strong.NET Architects who've worked in modern cloud and micro-services environments, or who can operate confidently across Node/TypeScript ecosystems, are absolutely encouraged to apply.
What matters most is architectural depth, SaaS scalability experience, and strong engineering principles.
The Role
This is ideal for someone who has progressed from hands-on engineering into architecture and still understands what great code and great systems look like.
You'll:
- Design large-scale, high-performance SaaS architectures
- Lead microservices and event-driven design initiatives
- Champion DevOps-aligned architecture patterns
- Work across distributed/offshore teams
- Operate comfortably at both strategic and deep technical levels
- Influence AI architecture and modern data practices

- Experience with microservices, event-driven systems
- Strong understanding of OLAP, OLTP, ETL & data warehousing
- DevOps-first mindset
