Interface design and the front‑end code that implements it, for a US product team.
You design and build interface work for a US product team. A change is a flow in their design system and the HTML and CSS that implement it. You check it with a keyboard and a screen reader, not only by looking at it.
What you do on the team On a placement, this is the work the US team expects.

Match the component library the product already uses
Use AI tools to draft a variant or a copy pass, then check it against the design system before it ships

How we check We review work you have shipped. A keyword on a resume is not enough. You need advanced or fluent English. You will be in standups, code reviews, and Slack with a US team. You use AI tools to draft a variant or a copy pass, then you check it against the design system before it ships. Every engineer is assessed on the four‑level AI fluency scale before a client meets them. See the four levels .
How a placement runs You join the client team and work in their repo, their standups, and their code reviews. You work US business hours from Mexico, Costa Rica, Colombia, Peru, Brazil, Chile, Argentina, or Uruguay. The placement is almost always a full‑time contract. You are paid the same amount every month in US dollars. The monthly invoice is for bookkeeping. Candidates never pay to apply or to join. How joining works .
