Hire senior front-end developers who care about the details
Senior front-end engineers who turn designs into fast, accessible interfaces and work in your repos and standups on US hours.
By the Ryz Labs team · Updated October 2026
Hiring front-end developers through Ryz Labs gets you senior engineers who own the whole user-facing layer: layout, accessibility, performance and the framework code that ties it together. They are vetted, in the top 1% of the engineers we interview, and they join your team with your designers, product managers and back-end engineers. They work on US business hours.
What our front-end developers work on
A senior front-end engineer is judged less by which framework they know and more by how the product feels: whether it loads fast, works with a keyboard, looks right on a small phone and survives a slow network. Our front-end engineers work on that layer every day, usually in React, Vue, Angular or Svelte.
- Design-to-code implementation from Figma, including responsive layouts, motion, and pixel-level fidelity with your design team.
- Design systems and component libraries with design tokens, Storybook documentation, visual regression tests and versioned releases.
- Accessibility remediation to WCAG 2.2 AA, including audits with axe and screen readers, and fixes across forms, navigation and modals.
- Performance programs that improve LCP, INP and CLS through image strategy, font loading, code splitting and caching.
- Marketing and content sites on Next.js, Astro or headless CMS platforms like Contentful, Sanity or Webflow.
- Complex web apps: editors, dashboards, drag-and-drop interfaces and real-time collaboration features.
Skills we vet for
- Modern CSS: Grid, Flexbox, container queries, cascade layers, :has(), logical properties, and when to use Tailwind, CSS Modules or a CSS-in-JS library.
- Semantic HTML and accessibility: landmarks, headings, form labeling, focus order, ARIA patterns from the APG, and testing with VoiceOver and NVDA.
- Web performance: the critical rendering path, Core Web Vitals, Lighthouse and WebPageTest, and real user monitoring.
- A modern framework in depth: React, Vue, Angular or Svelte, including its rendering model and state patterns.
- TypeScript for component props, API contracts and shared types with the back end.
- Browser APIs: Fetch, storage options, IntersectionObserver, the History API and Service Workers.
- Testing: component tests with Testing Library, end-to-end tests with Playwright, and visual regression with Chromatic or Percy.
- Collaboration with design: reading Figma specs and auto layout, pushing back on details that will not work, and proposing better alternatives.
How we vet front-end developers
Our recruiters source front-end engineers across Latin America and look closely at shipped work, not just résumés. ARC, our in-house system, ranks the pipeline so recruiters focus on the strongest candidates. Each candidate takes a structured NTRVSTA AI interview covering CSS, accessibility, performance and their main framework. Recruiters review candidates before and after, and you get a curated shortlist. AI scores are advisory. Humans make the decisions.
Sample interview topics
- Build a card layout that shows one column on narrow containers and three on wide ones, where the card itself changes layout based on its own width. When do you reach for container queries instead of media queries?
- A custom dropdown menu passes visual QA but fails accessibility review. Walk through the keyboard interactions, focus management, and ARIA roles and states it needs, or explain why a native element might be better.
- The product page's LCP is 4.5 seconds on mobile. How do you find out what the LCP element is and why it is slow, and what would you change with image formats, preload hints, fonts or server rendering?
- A layout shifts when an ad slot and web fonts load. Explain what causes CLS here and how you would fix each source.
- Design and product disagree on an interaction that you think will confuse keyboard users. How do you raise it, and what would you prototype to settle the question?
Ways to hire front-end developers
| Option | Best for | Trade-offs |
|---|
| Freelance marketplace | A landing page, a small site or a one-off component | Portfolios can look good while code quality and accessibility lag; low continuity |
| Staffing or recruiting agency | Permanent in-house front-end hires | Screening often stops at framework keywords; CSS and accessibility rarely tested; fees |
| In-house recruiting | Long-term owners of your product UI and design system | Large applicant volume and slow senior searches; heavy screening load on your team |
| Ryz Labs staff augmentation | Adding senior front-end engineers to your product team | $7,000 to $15,000 per engineer per month, scoped per team; your leads and designers set direction |
| Ryz Labs dedicated team | A redesign, design system or full front-end rebuild with its own lead | Larger engagement; best with clear ownership and design input on your side |
Ryz is not the right fit if you want to hire a freelancer by the hour through a self-serve marketplace, or if you need published rates before you talk to anyone.
Why hire front-end developers from Latin America
Latin America has a strong design and front-end culture. Agencies and product companies across Brazil, Argentina, Uruguay and Colombia have built interfaces for US and European brands for years, and that work has produced many senior engineers who are comfortable working closely with designers.
That closeness depends on overlap. When a designer in New York updates a Figma frame at 2pm, a front-end engineer working US hours can review it, ask questions and push a preview the same day. Strong English and a familiarity with US product practices make those exchanges easy.
