Job Title: UK&I Infrastructure / DevOps Lead
Reports To: UK&I SaT Head of Product
Role Type: Permanent FTE
Grade: Level 3 or 4 – Assistant Director / Manager or Associate Director / Senior Manager
About the team
The EY-Parthenon UKI AI product team is at a pivotal time for the future of consulting. We are within an enterprise: fast-moving, practical, commercially aware and disciplined about what we build.
Our remit is to productionise the highest value AI opportunities, to translate complex user needs into clear product direction, and work with technical teams to deliver products that are trusted, adopted and scalable.
This is a hands-on enterprise product role. You will not simply manage a backlog or coordinate delivery. You will understand senior user workflows, shape MVPs, drive key value & complexity trade-off decisions, and move products into real use.
The role
As Infrastructure / DevOps Lead, you will own the UKI SaT technical enablement required to move AI products and prototypes from experimentation to scalable deployment. You will work across enterprise technology, cloud, security, architecture, infosec, product and engineering teams to establish approved environments, deployment routes, data access patterns and reusable build guidance. This role is for someone who is technically credible, pragmatic in complex organisations and motivated by creating repeatable paths for teams to ship safely - not isolated pilots, local tools or one-off workarounds.
What you will do
- Create and implement the approved enterprise architecture for AI product development
- Create and implement approved Azure architecture, DevOps tooling and deployment patterns for product and agent development, ensuring environments are secure, scalable, observable and aligned to enterprise architecture requirements.
- Own CI/CD and Infrastructure as Code from prototype to production
- Own CI/CD and Infrastructure as Code practices to automate environment provisioning, security validation and controlled promotion from prototype through to production.
- Mobilise approved development environments
- Work with Global tech, Fabric and enterprise platform teams to establish secure build environments for product and agent development.
- Establish safe build patterns for different teams
- Define what can be built where, by whom, using which tools and under which controls, so engineers, data scientists and approved builders can move faster without creating unmanaged risk.
- Enable reusable data and API access
- Create scalable approaches for public, third-party and internal data integrations, reducing duplicated work around authentication, access, charging, governance and support.
- Resolve technical constraints that block delivery
- Work with Product Managers, engineers and Forward Deployed Engineers to diagnose recurring blockers and turn them into clear options, recommendations and implementation routes.
- Create reusable technical guidance
- Document approved architecture patterns, deployment pathways, environment rules, API integration models and DevOps practices so teams can build consistently.
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.
You are
- Technically credible
You understand cloud architecture, DevOps, data platforms, integration patterns and AI workflow infrastructure well enough to make practical decisions and challenge assumptions. - Enterprise-minded
You know the goal is not just to make one prototype work. The goal is to create reusable, secure and scalable patterns that allow multiple teams to build safely. - Pragmatic and structured
You can balance speed with control, break broad technical constraints into root causes, options, trade-offs, decision points and clear next steps. - A strong organisational navigator
You can work across Global technology, infrastructure, security, data, architecture, product and business teams, even where ownership is distributed.
What you definitely need
- Experience creating and implementing approved Azure architecture, DevOps tooling and deployment patterns for product, data or AI development.
- Experience owning CI/CD and Infrastructure as Code practices, including automated environment provisioning, security validation and controlled promotion across environments.
- Experience in cloud infrastructure, enterprise architecture, DevOps, platform engineering or technical delivery in a complex organisation.
- Strong understanding of cloud platforms, ideally Azure, and how enterprise environments are governed, operated, secured and monitored.
- Experience working with data platforms, APIs, authentication models, integration patterns and managed service models.
- Ability to define architecture patterns that balance speed, security, scalability, observability and maintainability.
- Experience working with security, infrastructure, governance or architecture teams to secure approvals and unblock delivery.
- Ability to diagnose technical constraints and translate them into clear recommendations and implementation plans.
- Strong stakeholder management and communication skills, including the ability to simplify complex technical trade-offs for senior technical and non-technical stakeholders.
- A bias to action and comfort making progress where the target architecture or ownership model is still being shaped.

What you might also have
- Experience with EY Fabric, Databricks, Azure DevOps, GitHub, Kubernetes, containerisation or equivalent enterprise DevOps platforms.
- Experience supporting AI, machine learning, data science, analytics or automation teams.
- Experience with LLM application architecture, RAG, vector stores, orchestration frameworks, model APIs or context management.
- Experience integrating third-party or public data APIs into enterprise environments.
- Experience defining platform operating models, developer experience, golden paths or paved-road architecture patterns.
- Experience in professional services, strategy, transactions, financial services or another complex regulated environment.
What success looks like
- Established clear build, deployment and environment routes for product and agent development.
- Created practical DevOps, CI/CD, access and API integration patterns that teams can reuse.
- Worked with enterprise platform, security and architecture teams to unblock priority constraints.
- Helped UKI SaT teams move from prototype to tested, scalable product with greater speed, safety and consistency.
Over time, success means UKI SaT has a trusted, repeatable technical foundation for AI product and automation development: teams know where to build, how to deploy, how to access data and APIs, and how to scale without reinventing the infrastructure model each time.
