At Karhoo, we are creating the largest and most transparent marketplace for ground transportation: the Karhoo Mobility Exchange.

By aggregating ground transport around the world, with regulated/licensed taxi and PHV fleets, we will give greater choice to consumers and corporates alike, bring new opportunities and data for the private and public sector, and help to enable ‘smart cities’ for citizens everywhere.

Karhoo, the first fully-integrated global, neutral, booking platform for regulated Taxis and PHVs was bought out of administration in January 2017, funded by RCI Bank and Services, the financial services provider for the Groupe Renault brands in the world and for the Nissan Group brands mainly in Europe.

RCI Bank and Services operates at the crossroads of three challenging worlds: cars, banking and services and is backing Karhoo via Flit Technologies Ltd, a new venture funded by RCI Bank and Services.

We are adapting the latest and greatest technologies to bring our product leaps and bounds into the next year. We are looking for an experienced Lead Web Engineer to join our team at this exciting and still very early stage in our company’s growth.

We’re looking for motivated individuals who can help push the Web team further through new tech and quality. Changing the mindset of how we can do things and advance our platform further ahead from both a scalability point of view as well as performance.

Quality is key and with this in mind you will have that mindset to make sure things are done in the best way they can be done.

If you’re looking for a opportunity to join a fast paced startup that promotes an environment for  collaborative culture and growth striving to delivering production quality code first time around then look no further!
