We're looking for a Senior Front\-End Developer to join the team building the web products behind Artec 3D's scanners and 3D\-scanning software — our customer\-facing storefront, our internal CRM, and our shared design system. This is a hands\-on, autonomous role across a real\-world mix of modern and legacy code: there is no front\-end lead above you — you own technical decisions, and mentoring more junior teammates is part of the role. You'll ship greenfield features on a cutting\-edge React 19 stack while incrementally retiring and modernizing the codebase it's replacing. What you'll work on • My Artec — our customer storefront. A Ruby on Rails app (HAML/ERB templates, jQuery, vanilla JS) that we're progressively migrating to a React 19 SPA (TanStack Router/Query, Rspack, Vanilla Extract). You'll both build new feature slices in the greenfield React app and maintain the legacy frontend. • Artec CRM — our internal customer\-relationship platform: a mature React SPA (React 18, Redux Toolkit, Vite), currently migrating its routing to TanStack Router. • Artec UI — our shared component library and design system (React 19, Vanilla Extract, Storybook, Chromatic visual regression), consumed by the products above. • Occasionally, internal tooling (a Next.js portal).

About Artec 3D

Tasks:


  • Build new features end\-to\-end on a modern React \+ TypeScript stack, and maintain/refactor legacy template\-and\-jQuery code where it still lives — including occasional edits to old Ruby (HAML/ERB) templates.

  • Drive incremental migrations from legacy to greenfield — making them safe, reviewable, and shippable in small steps.

  • Work autonomously and own front\-end technical decisions

  • Collaborate closely with backend, QA, project management, and design teams to plan, agree on API/permission contracts, and deliver features end\-to\-end.

  • Contribute to and consume the shared design system; uphold accessibility and visual consistency.

  • Take part in code reviews, write tests, and own the quality of what you ship.

We offer:


  • A great office, modern equipment

  • Autonomy and creativity in the area of your responsibility

  • Official salary, medical insurance

  • Hot lunches in the office

  • Flexible schedule

  • A collection of board games

Required skills and competence:


  • Strong JavaScript/TypeScript fundamentals and solid HTML/CSS.

  • Deep, production\-level experience with React and its modern ecosystem (hooks, routing, server\-state/data\-fetching, forms).

  • Hands\-on experience with modern build tooling (Rspack / Vite / webpack).

  • CSS\-in\-JS / CSS Modules styling

  • Comfortable working in a large existing codebase: reading, refactoring, and safely changing code you didn't write — including older/legacy frontends, and not shying away from occasional fixes in legacy Ruby templates.

  • Sound grasp of frontend architecture and the discipline to apply it consistently across a team.

  • Experience leading legacy\-to\-modern migrations in production.

  • Ability to work autonomously with little supervision, and to mentor less experienced engineers.

  • Experience writing automated tests and collaborating through code review.

  • Able to work effectively in a distributed, asynchronous team and communicate clearly in English.

Will be a plus:


  • Experience with TanStack Router / TanStack Query (or React Query / RTK Query) and Redux Toolkit.

  • Building or maintaining a design system / component library (Storybook, visual regression testing).

  • i18n / localization experience.

  • Some comfort with backend work alongside Ruby on Rails / PHP backends.
