Loot philosophy and culture

Strong opinions

Our team work really hard to get everything right. We're believers in 1000 no's to every yes. The work we do is the product of many discussions involving many opinions and ideas. Everyone's idea/opinion is welcome, in fact we encourage everyone to share theirs, especially strong ones, but these should be held loosely when it comes to presenting them to the team.

We're looking to bring on people who will inject new opinions and ideas, just as we'll show them our ideas and opinions, changing everyone for the better.


Carrying on from sharing opinions and ideas - we think diverse collaboration is key to making great products and software. Although this job description is predominantly for an engineer who would spend most of their time working on our Ruby Gems, there would be nothing to stop them from submitting a pull request for one of our iOS app (or any other project). Again, we'd encourage it. And it doesn't stop there. Got an idea for some UI changes? Speak to Nick, our UI designer. Got some ideas for marketing or features, speak to Ollie or Chris.

Our workflow is very much like managing an open source software project. Changes are made, PRs are opened, tests are run, reviews and discussions are had, changes perhaps get made again, code gets merged. Any engineer could feedback on any other engineer's PR, it doesn't matter what their discipline is, although PRs will commonly be reviewed by another in your field.

Open source

Aaaaaand carrying on from collaboration - we like open source development a lot, and where we can we share our work and contribute to projects. We hope to open source more of our projects as we get more time and resource to do so. Ultimately this is because we feel that the world can build better software when it works together. We couldn't have launched so quickly without using some great OSS frameworks. We think using (and perhaps improving) an existing project rather than re-inventing it is way better for everyone.

When our team contributes to the community:

This is why we want our team to strive to be leaders in their fields, having a strong presence in their communities, be it via activity online (social, blog, OSS) or at conferences and meet-ups (hopefully both).
