  • Write reusable code and libraries (with matching documentation) to a standard which makes it quick and easy to maintain the code in the future
  • Refactor the current codebase to improve its maintainability
  • Continuously develop your skills and use your knowledge to hand it over to the product through day-to-day decisions
  • Establish and actively participate in the company’s frontend developers group, bring fresh ideas on improving the code, architecture and software development process.

Your Experience

Must have:

  • Expert-level knowledge of HTML/CSS and JavaScript with at least 5 years of experience developing, shipping, and maintaining web applications.

Your decision to complete the form and your answer will not harm you in any way.
