Rosalie Wagner is a Berlin-based French type designer and font engineer with 11 years of experience creating typefaces for print and screen, as well as advising on type-driven projects like books, logos and signage. She blends hands-on design with engineering rigor—handling outline corrections, hinting, spacing/kerning, OpenType features and build automation—to take fonts from concept through production. Rosalie has contributed build automation and variable font tooling to high-profile open-source projects such as JetBrains Mono and improved metadata and designer profiles across the Google Fonts repository. Her background includes post-master research in type design from ANRT and a DNSEP in graphic design, informing a practice that straddles research, craft and tooling. She also brings teaching and accessibility experience, having tutored students with dyslexia and taught art, which shapes her attention to legibility and usable typography. Expect a collaborator who combines meticulous technical workflows with a designer’s sensitivity to form and context.
