Front End Design Engineer
Seamflow, London
The role
A Front End Design Engineer thinks in finished interfaces, not mockups or components in isolation. A technical reviewer at a notified body spends their day inside a 400-page technical file, cross-referencing clauses, checking test reports against standards, and deciding whether a medical device is safe to sell. Today they do that in Word, Acrobat and a spreadsheet someone built in 2011. The interface they use decides how fast they work and whether they trust the AI sitting next to them.
You own that interface. Layout, typography, interaction, motion, the design system underneath it, and the React that ships it. You decide how a reviewer sees a finding, how they correct a model that got it wrong, and how a hundred fields of dense regulatory data become something a person can actually read. You sketch it, build it, ship it, then sit next to someone using it and find out what you got wrong. You'll ship to production in your first week.
