Senior Frontend Developer

Warsaw, Poznan, Remote

We are looking for talented and ambitious senior frontend developers to join our company to work on challenging ongoing projects (some MVPs can also be expected time to time).

We work in small teams using Agile methodologies (mostly SCRUM) and work for clients from different time zones (+9h is possible). We focus on long-lasting partnerships with ongoing projects rather than short term cooperation with startups. We really focus on delivering quality solutions, quick and dirty is not an option most of the time and our clients do understand that. Apart from clients' projects we also spend time on our internal projects, tools and open source.

You should definitely talk to us if you have very good knowledge of computer science, web development and great coding skills. You should be able to work on your own, know our best practices and deliver high quality code which is easy to understand and maintain.
You should be ready to supervise and mentor less experienced team members, estimate features and propose alternative solutions to encountered problems.

What do we require?

  • preferrably technical education (we hire software engineers mostly)
  • excellent knowledge of HTML / CSS
  • excellent knowledge of Javascript (functional programming, reactive programming, state management patterns)
  • excellent knowledge of any Javascript framework (vue / angular/ react etc.)
  • very good knowledge of JS / CSS performance benchmarking and optimization (steady FPS animation, minimizing first frame paint time etc.)
  • very good knowledge of modern web apis (cache, storage, workers etc.)
  • very good knowledge of backend integrations (REST api, web sockets, server side rendering etc.)
  • very good knowledge of common tools (grunt / gulp / browserify / webpack etc.)
  • very good knowledge of CSS compatibility issues and polyfills
  • very good knowledge of SASS / LESS
  • very good knowledge of git
  • good knowledge of rendering technologies (D3, svg, canvas, webGL etc.)
  • good knowledge of browser implementations and quirks
  • good knowledge on Ruby and Ruby on Rails
  • very good english (we work with foreign clients only)
Features you should have implemented so far:
  • lots of pages with different page layouts
  • integration with UI components, form controls (auto complete selectors, phone inputs, text editors etc) with full responsive design
  • project with heavy use of jQuery or similar library
  • complex project written in any JS framework
  • complex integration with backend
  • integration with Asset Pipeline in Rails project
  • configured any build tool for the project
