Design Systems Engineer (Remote, Cartago)

Full‑time, remote (Latin America)

About the role

Blacksmith Agency builds websites and marketing programs for clients across the US. As a Design Systems Engineer at Blacksmith, you own how client design systems get built. You take a brand and a few reference sites, then extract the pattern into a working system: tokens, variables, modes, and core components a build pipeline can execute without asking you questions. Precision is the job. This is a senior, systems‑first seat. Not one‑off pages, not maintenance. You stand up new systems fast and get them right the first time, across several client brands at once.

Responsibilities

• Build token architecture in Figma using variables, modes, and semantic naming that our pipeline can read predictably.
• Ship core component libraries that hold up across an entire site, not just a homepage.
• Document the system so a developer or an automated pipeline can execute it without questions.
• Work across several client brands at once, each looking distinctly different, with the same structural rigor.

Requirements

• 4+ years designing for the web, with real design‑system work in your portfolio.
• Fluency in Figma variables, component properties, auto layout, and variants – actual architecture, not just tidy files.
• A portfolio where the work looks different from client to client but the rigor underneath is the same.
• Strong English and overlap with US business hours.
