Front-End Engineer (Senior)

Engineering / Mexico City / Remote / Full-time / Hybrid

Salary: 40k–70k USD

02 / ABOUT THIS ROLE

The role

You own the pixel-to-database seam: interfaces that load fast, read beautifully and never break accessibility. Our clients run ministries, banks and hospital networks — your HTML is load-bearing infrastructure.

What you'll do

  • Ship design systems (tokens, components, docs) consumed by multiple products
  • Hold performance budgets: Core Web Vitals in the green, measured on real users, not lab
  • Make accessibility a first-class feature (WCAG 2.2 AA audits, keyboard flows, screen readers)
  • Lead SSR rendering strategy and hydration cost reviews


Non-negotiable requirements (all verifiable)

  • Bachelor's degree in CS, Software Engineering, Interaction Design or equivalent — diploma with folio, we verify with the institution
  • One senior verifiable certification: Meta Front-End Developer Professional, W3Cx Front-End, or IAAP CPACC (accessibility) — credential ID checked
  • 5+ years shipping production front-end with a public portfolio: 2+ projects where you can defend every rendering decision
  • Git history that survives scrutiny: PRs, reviews, constructive disagreements — bring your real account, not a curated fork
  • English C1 — technical conversations and client workshops in English are the daily baseline
  • Live test: you will fix a broken layout and a hydration bug in front of us


What makes you stand out

  • Contributions to a major OSS front-end framework or library
  • You have designed and documented a design token pipeline
  • Motion craft (spring physics, choreography) without shipping jank
