Currently at DoorDash
I design AI-native products
where humans and AI
share the workspace.
…and I help design teams scale that model with proactive and reactive design automations.
Brennan Martin
Staff Product Designer / Design Engineer, AI Enablement
I lead design for DoorDash’s AI support & tooling strategy — systems where agents, automation, and product judgment share one workspace.
Last 6 months
-
Led design for one global AI-native support platform across markets instead of several disconnected tools.
-
Built an AI case assistant that turns multi-step casework into guided actions, keeping agents focused on judgment instead of tool choreography.
-
Increased semi-autonomous case assistance coverage from 46% to 89% with workflow prediction and agentic case-work tooling.
-
Built the Pace Car framework designers use to prototype in code and ship clean production slices — 1,023 commits · ~126 merges · single-digit days from approval to ship.
-
Personally shipped 85 PRs — 82% substantial or complex, only 4% minor fixes.
The work behind those results
-
One global support platform across two acquired companies
Replaced three legacy tools with one production workspace for 200+ agents — DoorDash, Wolt, and Deliveroo operating models in the same console.
-
AI assistant that expands guided support coverage
Predicts the next workflow and guides the case. Coverage 46% → 89%, with 94% accuracy on the highest-volume path.
-
A workflow that lets designers ship UI in code
Two lanes: explore ahead in a shared prototype branch, rebuild only clean slices onto master — so production never absorbs the mess of exploration.
What people say
"He's been pivotal in getting dozens of people set up with development environments for working on DoorDash web-based projects. He recommends the most AI tools, and he does it proactively, really caring that people have awareness of the things they can use to go faster."
"Brennan pairs vision with a very fast GTM and he's very quick to iterate, mock up designs, bring people along."
"He's done an awesome job stepping in to keep the team running and going in the many, many quarters that we have not had a PM. I've appreciated how leaned in he's been and how company-first he's been along the way, even despite having far more asked of him than is reasonable for most designers."
