Frontend Engineer (Next.js / Docs Platform) to $3000

About the project

We are Smart-UI, a custom web development agency.

Our client is a major data/AI company in the Apache Spark ecosystem.

We’re looking for a Frontend Engineer who will help us rebuild and modernize the official documentation website.

This is not a typical “marketing website” job - it’s a developer documentation platform with:

• new information architecture for docs,
• modern stack (Next.js, TypeScript, MDX, Tailwind or similar),
• versioned documentation,
• global search,
• quickstarts & code examples.

You will work closely with our team and the client’s team (architects, product, devrel).

Responsibilities

• Implement a new documentation website using Next.js + TypeScript + MDX (or a similar stack agreed with the client).
• Work with documentation structure and navigation: sidebars, versioning, cross-links, IA.
• Build reusable UI components for docs: code blocks, tabs, callouts, API refs, navigation blocks etc.
• Integrate global search (Algolia / Pagefind / other).
• Set up and maintain CI/CD pipeline for the docs site (preview builds, staging, production).
• Collaborate with the client on content migration (existing Spark docs, PySpark docs, quickstarts).
• Take care of performance, accessibility and SEO basics for the docs platform.
• Participate in technical discussions, propose and defend architectural decisions.

Requirements

• 4+ years of commercial experience in frontend / web development.
• Strong experience with React and Next.js (SSR, SSG, routing, data fetching).
• Confident in TypeScript (not just copy-paste).

• Experience building documentation websites or developer portals using:

  • Markdown / MDX
  • and/or Docusaurus / MkDocs / Astro / Gatsby / similar.

   

• Good understanding of:

  • routing & navigation patterns for docs,
  • performance optimization (Lighthouse 80+),
  • accessibility basics (ARIA, keyboard navigation).

   

• Experience working with Git and Git-based workflows (PRs, code review, branching).
• English: Upper-Intermediate+ (you should be comfortable on calls with the client).

Nice to have

• Experience with Algolia, Pagefind or other search solutions.
• Experience with versioned documentation (multiple versions of docs).
• Understanding of data engineering / Apache Spark / Python – not mandatory, but a big plus.
• Open-source contributions or experience maintaining developer-facing docs.
• Experience with CI/CD (GitHub Actions, GitLab CI, etc.).

We offer

• Work on a high-impact, visible project in the Apache Spark / data engineering ecosystem.
• Direct communication with a strong international client (architects, devrel, product).
• Fully remote work, flexible schedule within EU time zones.
• Long-term cooperation if we’re a good match.
• Competitive hourly rate / monthly compensation (to be discussed individually).
