Head of Architecture & Applications
Warner Hotels operates a portfolio of 100+ technology services across a modern, cloud-first estate — but the application landscape is fragmented, point-to-point integrations are the norm, and there is no enterprise architecture function to govern where the estate is going. The result is cost, complexity, and constraint on the business's ability to grow.
We are looking for a Head of Architecture & Applications who can bring order, clarity and direction to this landscape. This role sits at the intersection of technical rigour and commercial pragmatism — someone who can define the target architecture, govern the application portfolio, and ensure that every application Warner runs is earning its place.
As the owner of Warner's enterprise architecture and application portfolio, you will define how the technology estate should evolve — across commercial applications (iStay, Maestro, Zonal), corporate platforms (ERPx, ElementSuite, Coupa), and the integrations that connect them. You will set and govern architecture standards, lead the application rationalisation agenda, accelerate automation, and ensure that our platform choices support — not constrain — the business's strategic ambitions.
Why Join Us?
- Clean mandate: The architecture function does not exist today — you will build it from the ground up with full CTO sponsorship.
- Rationalisation and AI Enabled automation agenda to drive.
Key Responsibilities
Define & Own the Enterprise Architecture
- Establish and maintain Warner's enterprise architecture framework — covering application, data, integration, and infrastructure layers.
- Define target architecture principles, standards, and guardrails that all technology decisions are measured against.
- Lead architecture reviews for all significant change initiatives, ensuring alignment to the target state.
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.
Application Portfolio Management
- Own the full application portfolio — 160+ services across commercial, hotel operations, F&B, corporate and back-office domains
- Lead the application rationalisation roadmap: identifying duplication, underutilisation and consolidation opportunities.
- Manage application vendor relationships and licence agreements, ensuring value for money and strategic alignment.
Integration Architecture & API Governance
- Define Warner's integration architecture — moving from point-to-point towards an API-first, event-driven model.
- Govern the integration landscape to reduce complexity, eliminate technical debt, and improve reliability.
- Work closely with the Head of Data & Digital Engineering to ensure the data platform and digital products are built on sound integration foundations.
Technology Strategy & Governance
- Contribute to the overall IT strategy — specifically the 'Simplify the Core' pillar.
- Chair architecture governance forums and ensure all significant technology decisions are reviewed, documented, and aligned.
- Provide technology roadmapping capability, ensuring the business has visibility of where the estate is going and why.
