We’re looking to hire a full-time, contract developer to join our team. Your job will be, most simply, to make Tropy as good as it can be, working on any part of the project to help advance that goal. This position is for someone with a wide range of skills: you should be comfortable obsessing over the frame rate of a user interface animation or designing a sync architecture from scratch. Your work might include improving the Tropy desktop software or building back-end services to power new features. As part of a small team, you’ll have responsibility over core components of the project and the freedom to experiment and find creative solutions to tough problems. Most importantly, you’ll participate in a vibrant global open-source community with amazing community developers and passionate users.
