This role is in our Media Solutions team, handling web analytics, data engineering and client-side JavaScript snippet development in Tag Manager and A/B testing tools. As such we're looking for a JavaScript developer who's looking to broaden their skill set in a media agency.

Impression is a multi-award winning, high growth digital marketing agency based in Nottingham, Manchester and London.
