Why we need you

The Conversion Rate Optimization Agency helps clients optimize their websites and their businesses. This involves identifying areas that can be improved in terms of User experience, developing several hypotheses that will generate growth, then acting by implementing changes into the clients’ websites: transposing testing ideas into reality.

What your job is about

Your job is about helping our clients to grow their businesses by prototyping ideas and constantly developing the best version of their website. This ultimately helps users across the world to have the best possible interaction with web applications.

This means creating testing experiments by creating CSS / Javascript code and combining it with features of the Omniconvert platform. These experiments will enhance both the design and functionality of the client’s website. They can range from simple tasks of moving sections or redesigning elements on the page, to complex tasks of creating new areas of content with which the users interact, adding features to the website while linking several experiments throughout the conversion funnel.

The role involves working in an ever-evolving environment, using the Kanban methodology. Does that sound like a challenge? We believe it does.

Besides the professional challenge, the role involves working in a great environment, being part of an awesome team, taking part in after-work social activities, participating in contests such as ping-pong or cooking and much more.
