Job Description
Contribute to building and evolving the platform (infrastructure + reusable abstractions) that standardises data engineering workloads (batch/streaming pipelines, data processing) and traditional ML workflows (feature engineering, training, batch/real-time serving) across teams
Implement platform-level IaC, CI/CD, and environment management to support consistent, reproducible workloads across dev/test/prod
Build and maintain components using Python and Spark for data processing, shared datasets, and platform services
Contribute to shared services for data and ML lifecycle management (data pipelines, experiment tracking, versioning, lineage, permissions), aligned to enterprise governance (e.g. Unity Catalog)
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.
Support the implementation and operation of a centralised AgentOps capability (LLM gateway, tool integration, prompt and version management)
Contribute to agent-specific lifecycle and safety controls (evaluation pipelines, guardrails, access control), with guidance from senior engineers
Enhance observability across both domains:
- Data & ML Ops: data quality, pipeline reliability, model performance
- Agent Ops: traces, responses, evaluations, cost and behaviour monitoring
Contribute to problem solving across platform reliability, performance, and security for data, ML, and agent workloads
Apply security and compliance best practices (RBAC/ACLs, secure configuration, identity and access management), supporting a secure-by-default platform design
Collaborate with Data Engineers, Data Scientists, and ML Engineers to enable adoption of platform capabilities across ASOS Tech
Contribute to documentation, standards, and best practices across the platform
