Episode notes
Design Engineer Is The New Full Stack
- The design engineer blends aesthetic taste with deep UX and implementation knowledge to own problems end-to-end.
- Wes and Scott argue this role will be as pivotal as full-stack devs because UIs now require interaction thinking, performance and copy sense.
Taste Is About Interaction Not Just Looks
- AI-generated UIs often share surface style but lack character and the interaction-level thought that makes products usable.
- Wes compares it to cookie-cutter houses and points to apps (Threads vs Twitter) where usability, not visuals, exposes poor design.
Write Unit First Then Record End To End Tours
- Prioritize unit tests for complex logic and end-to-end Playwright tests for flows; record interactive sessions to make deterministic tests.
- Wes wrote exhaustive unit cases for social-URL parsing, and Scott recommends browser-recorded E2E tours to catch regressions.
