More about the Job

You will be working as part of a small, dynamic team in a modern, open-source
development environment. This role is full-time and we are very happy with

We generally work remotely (with strong contingents in London and Berlin),
using asynchronous communication (email, IRC, GitHub) but with standups,
developer meetings and demos most days (Skype, Google Hangout) and real-world
gatherings more than twice a year including at the Open Knowledge Festival. We
also try and ensure our developers can attend at least one open source
conference a year.

At each level of our software stack we use best-in-class open source software,
including Python, Nose, Travis CI and Coveralls, Sphinx and Read the Docs,
Flask, Jinja2, Solr, PostgreSQL and SQLAlchemy, JavaScript and jQuery,
Bootstrap, Git and Github, and Transifex.

We iterate quickly, and publish working, open-source code early and often.

All of our code is on github - it is open to public scrutiny, and we encourage
contributions from third-party developers. This means that we have to write
exceptionally clear, readable, well-tested code with excellent documentation.

All code contributions, whether from internal or external developers, are made
with GitHub pull requests and we do code reviews in the open on GitHub.

We are engaged with a large and active community of users, developers and
translators of our open source software, via our mailing lists, GitHub issues
and pull requests,

public developer meetings, Stack Overflow and Transifex. We support users in
getting started with our software, encourage and mentor new developers, and
take on feedback and suggestions for the next releases.
