Python Developer

London, United Kingdom


What Now?! is proud to bring you London’s smartest map and city guide, helping you discover the best parts of the city as you experience it, without worrying about roaming charges. Since our soft launch in April 2014 we have had over 400,000 downloads of our app - with zero spent on marketing.

What Now?! recently partnered with the Transfer and Activities Bank (TAB) division of the Hotelbeds Group to deliver a mobile-first booking solution for in-destination tourism - working with various partners like hotels to deliver both added value to guests as well as an additional revenue stream.

Our MVP became the Official Tourist App for London in conjunction with the Tourism Board/Mayor's Office. Prior to launch, we were showcased by TechCrunch as one of their Top 15 European Startups at their Disrupt event in Berlin, as well as by PhoCusWright at their Travel Innovation Summit in the US (the largest such event in the global travel industry) as one of 2013’s Top Travel Innovations. We were also shortlisted for the UK’s Most Innovative Mobile Company as part of the UK government’s Department of Trade and Investment’s Smart UK Initiative. In Autumn 2014, TechCrunch invited us back on stage at their Disrupt conference in London as one of their successful Startup Battlefield companies (which was hugely flattering as previous alumni have included Dropbox and Yammer!).


The role is to take on ownership of server-side components of the What Now?! service, under the direction of the CTO and in collaboration with the iOS and Android developers. This will involve a mixture of software development and dev-ops, including design-code-test of brand new functionality, learning and extending the existing systems, adapting for scale, and generally being ready for anything that’s required in this fast-moving startup environment.

You should want to code great apps, always trying to find a better, cleaner, more efficient ways to solve a problem, take on a task, learn quickly, and provide solutions, not just questions.
