Role Overview

We are looking for an experienced Enterprise Architect to support the design and delivery of scalable Data and AI architecture across a major enterprise environment.

The successful candidate will bring broad technical expertise across Machine Learning, Generative AI, Large Language Models and Agentic AI. You will be responsible for translating complex technical requirements into reusable enterprise architecture patterns that can be adopted across multiple teams and programmes.

Key Responsibilities

  • Define enterprise architecture principles, standards and reusable design patterns for Data and AI solutions.
  • Design scalable, secure and cloud-native AI architectures across Azure and/or Google Cloud Platform.
  • Provide architectural leadership across Machine Learning, Generative AI, LLM and Agentic AI initiatives.
  • Design patterns for hosting, fine-tuning, optimising and orchestrating Large Language Models.
  • Develop architecture covering prompt engineering, embeddings, vector search and retrieval-augmented generation.
  • Define MLOps and LLMOps patterns supporting model development, deployment, monitoring, governance and lifecycle management.
  • Design Agentic AI architectures incorporating tool use, memory, orchestration and multi-agent workflows.
  • Ensure AI solutions integrate effectively with enterprise data platforms, distributed systems and existing technology estates.
  • Assess data sourcing patterns, platform constraints, security requirements and scalability considerations.
  • Work closely with engineering, data, cloud, security and business stakeholders to translate requirements into practical architectural solutions.
  • Produce clear architectural documentation, roadmaps, reference architectures and governance standards.
  • Support technical decision-making and ensure solutions align with wider enterprise technology strategy.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

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.
