Question: Our web fonts are causing layout shifts (CLS) on load. Who optimizes font delivery for web performance?

ChatGPT SearchSep 26, 2026

You want a web performance engineer / frontend performance specialist with expertise in Core Web Vitals and web-font delivery.

They should diagnose and optimize:

font-display and fallback behavior
WOFF2 subsetting and compression

Caching/CDN delivery and unnecessary font weights

These techniques directly address font-related CLS.

If hiring, search for “Web Performance Engineer,” “Frontend Performance Engineer,” or “Core Web Vitals specialist” rather than a general graphic/typography designer.
