Senior Workday Technical Director - Integration, Extend & AI

Workday Technical Director Integration, Extend and AI | Design Authority Location: UK, remote-first. Client travel across UK and EMEA as programmes require.
Type: Permanent
Package: £120k plus bonus, plus equity or profit share
Start: Flexible. We will wait for the right person.

Why this role exists Most Workday partners sell delivery capacity. We are building a platform business on top of Workday, and the difference between those two things is architecture.

We need one person who owns the technical direction of everything we build: the integration patterns, the Extend estate, the orchestration layer, and the AI proposition that sits across all of it. Not a reviewer of other people's designs. The design authority. Final say.

This is a role for someone who has already run global Workday delivery at scale, has done the governance frameworks and the steering committees and the programme recoveries, and has reached the point where the constraint on their impact is the organisation around them rather than the problem in front of them.

What you will own Architecture and design authority

• Own the reference architecture for Workday integration, Extend and orchestration across every client engagement
• Set and govern API strategy, event-driven design patterns and reusable accelerators
• Hold final technical sign-off on solution designs, integration design documents and data mapping specifications
• Chair the design review board. Kill bad designs early and say why

AI and Extend proposition

• Build our AI capability into a productised, repeatable offering rather than a set of one-off client experiments
• Own our position on Workday AI agents, SANA and adjacent orchestration tooling
• Define where AI genuinely removes cost and risk from HR, payroll and finance operations, and where it is theatre
• Take that proposition to market alongside our sales and partner teams

Regulated and secure delivery

• Act as technical lead on transformation programmes in regulated and public sector environments
• Own compliance, security architecture and scalability posture across cleared engagements
• Represent us in security assurance and client design authority forums
