Head of UX & Product Design · Hybrid Barcelona & London, or Remote · UK & EU right to work
UX and Product Design Leadership for SaaS, AI, and Enterprise Products.Complex products, simple UX.
Hi, I'm Derry Birkett. I help SaaS and AI companies decide what to build from research, not opinion, then ship it through design systems teams actually use. Now Head of Product Design at Capcade. Before that I led UX at CloudBees and design systems at Oracle NetSuite.I'm Derry, Head of Product Design at Capcade. I led UX at CloudBees and design systems at Oracle NetSuite, and I still ship the hard stuff myself.
I work best where depth matters: untangling information architecture, building research rigour, and setting the quality standards that make the team around me better.
Four anchor cases show the through-line: organisation design at CloudBees, enterprise systems at Oracle Netsuite, 0→1 product work at Exabyte, and full-stack UX leadership at Telanto.
I write about design systems, UX maturity, and AI-assisted product work, and keep a blog archive of demos and experiments when the idea needs to be felt rather than explained.

The Audit Agent Doesn't Get Bored
I built an agent whose only job is to catch when my autonomous pipeline breaks. It worked perfectly for two weeks straight. The thing it caught was me.

The Skills That Only Worked On One Machine
I opened Claude Code on my phone mid-task and /pickup didn't exist. The cause was a submodule nobody had initialized, and the fix taught me why --recursive is the wrong default.

The Research Problem I Solved with a Slash Command
