About Flowminder

Flowminder is a pioneering, internationally operating non-profit organisation that supports disaster relief and development efforts through several products including the analysis of data gained from mobile phones and household surveys in ethical, privacy and security preserving manners.


About the role

We are seeking a full-stack developer with a frontend bias and a passion for designing and building products that deliver impact to join our small engineering team. The right person will take the lead on continuing development of an open source, data intensive, geospatial web application. The role will involve being the primary developer of the front  (https://github.com/Flowminder/flowkit-ui) and back (https://github.com/Flowminder/flowkit-ui-backend) end of the application, and you will have the opportunity to be part of actively driving the direction of future development.

The ideal candidate will be able to take the technical lead on developing this project and have a track record of building high quality web apps, and we’d love it if you had an interest in data visualisation. We believe that engineers interacting with end users leads to better, more impactful tools. You will be keen to work with users to understand their needs and perspectives and factor this in to what you design and build. The product will form an important part of our growing ecosystem of tools targeted at the humanitarian sector, which are focused on delivering insights drawn from combining telecoms data with robust geospatial analysis.

We value autonomy, curiosity, and like people who care about writing good code, and making the world a better place.
