About Wingify

If a flashmob could be manifested as a physical space, it would be our office. We are creative, self-organizing, tech-worshipping, mutually-respectful, data-obsessed people. When we are not building great products, we are simply being awesome!

Wingify's flagship product VWO is a lucid platform for A/B testing tool that helps businesses improve their websites by tracking visitor behaviour, testing improvement ideas and targeting visitors for personalisation. It's used by 4,000 businesses such as Target, Disney, Sears, Tinkoff Bank and Flight Centre amongst others. VWO is the world's easiest A/B testing tool. Tweak, optimize & personalize your website and apps with minimal IT help.

Wingify acquired US-based visitor analytics solution Navilytics. With this acquisition, Wingify has made significant progress in its transformation from being the first 'no-coding required' A/B testing tool in 2010 to becoming the first full-featured conversion optimization platform in the world.

Role & Responsibilities

• Development of Core JavaScript libraries.
• Writing reusable code or modules that can be used across all the JavaScript libraries.
• Talking about your work - we love open source software, we heavily use them, and talking about how we use them is the least we can do to help the community. See our engineering blog and our GitHub page

• Passion for writing Vanilla JavaScript
• Strong knowledge and experience in JavaScript, HTML, and CSS.

Perks, Benefits and Work Culture

Testimonial from a designer : One of the things I love about the design team at Wingify is the fact that every designer has a style which is unique to them. The second best thing is non-compliance to pre-existing rules for new products. So I just don't follow guidelines, I help create them.'
