Salary: We would like to hear your salary expectations when we discuss your application with you over the phone. The benefits package is listed below.
The Opportunity
We are looking for an experienced AI Platform Architect to define, design and evolve an enterprise-grade AI platform spanning Microsoft Azure and AWS.
This is a senior architectural role with ownership of the platform's overall technical vision, architecture and roadmap. You will shape a scalable, secure and cost-effective environment supporting traditional machine learning, model training and hosting, Generative AI, advanced AI capabilities and emerging technologies.
Working closely with engineering, security, data, enterprise architecture and business teams, you will establish the architectural standards and capabilities that enable AI/ML teams to take solutions from experimentation through to secure, production-ready deployment.
What You'll Be Doing
- Own the end-to-end architecture of a multi-cloud AI platform across Azure and AWS.
- Define platform capabilities covering ML training pipelines, feature stores, model hosting, observability, MLOps/AIOps, GenAI orchestration, vector search, RAG and agent frameworks.
- Develop scalable architectures for Generative AI, including LLM hosting, fine-tuning, prompt orchestration, evaluation, content filtering and AI safety controls.
- Evaluate cloud-native, open-source and third-party AI technologies and make evidence-based tooling recommendations.
- Design secure integration patterns between Azure, AWS and internal enterprise systems.
- Provide architectural direction for AI solutions, ensuring they make effective use of platform capabilities and meet security, governance and scalability requirements.
- Produce high-quality architecture blueprints, reference architectures, capability models, C4 diagrams, standards, decision records and runbooks.
- Oversee implementation to ensure platform components are delivered in line with agreed architectural principles.
- Embed security, privacy, regulatory and Responsible AI requirements into the platform architecture.
- Drive cost optimisation across compute, storage and AI inference workloads while maintaining resilience, reliability and performance.
- Represent the AI platform within architecture and technology governance forums.
- Work with data scientists, ML engineers, platform engineers, product teams and business stakeholders to enable a broad range of AI workloads.
- Provide technical guidance, troubleshoot complex platform challenges and mentor engineering teams.
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

You'll bring proven experience designing and architecting enterprise-scale AI/ML platforms, ideally across both Azure and AWS.
You should have:
- Strong experience architecting AI/ML platforms in complex cloud environments.
- Deep knowledge of ML platform capabilities including training pipelines, orchestration, feature stores, model hosting, observability and MLOps.
- Strong Generative AI architecture experience, including LLMs, RAG, vector databases, prompt orchestration, guardrails and evaluation frameworks.
- Excellent understanding of multi-cloud architecture, networking, IAM, security and cross-cloud integration.
- Experience assessing and selecting AI technologies such as MLflow, Kubeflow, SageMaker, Azure Machine Learning, Databricks, vector databases and inference frameworks.
- Knowledge of Responsible AI, data protection and AI governance, including GDPR and model risk management principles.
- Strong architecture modelling and technical documentation skills.
- Experience designing scalable and cost-efficient architectures for AI training, fine-tuning and inference.
- The ability to solve complex technical problems and provide architectural leadership to engineering teams.
