We're looking for an experienced backend developer. In the role you will play a key part in developing and guiding our product. You should have broad practical knowledge in different areas of software development. We're looking for a developer whose existing skills, experience, and knowledge will complement and support our growing team. As we’re an early stage startup you’ll have the opportunity to significantly influence the trajectory of our products.
Our core product is a single page vue.js application with a Python backend. We use CircleCI for continuous integration and write a lot of tests. You aren't expected to be familiar with all of these technologies and will have the time and support to develop your skills and understanding on the job.
How We Operate
Our engineers are split into small multi-discipline teams of 3-7 people (engineers, product designers, UX, product managers). Teams are problem-focused and work on high level objectives, e.g. our Research & Collaboration Team is looking at ways the site’s UX can be improved to increase retention of users. Teams use 6-12 week cycles to meet the objectives with continuous delivery throughout the cycle.
We have a strong belief in the value of testing - both integration and unit testing. All code goes through code review.
Deep work is valued throughout the company. We favour async communication over Slack and Notion. When we need to communicate in real-time we try to group meetings together to give everyone bigger blocks of interruption-free time.
Our problem-focused teams allow for regular innovation, which we foster further with quarterly hack-days, building things like study debriefing tools and experiments comparing our platform to competitors like MTurk.
Continuous learning and development is strongly encouraged. Everyone gets a personal development budget which they can put towards things like books, courses and conferences, and reserve times every fortnight for learning new things or working on creative side-projects.
We’re aware of the challenges of being a remote worker and work hard to foster team-spirit. We encourage remote chats over coffee with colleagues and have regular team meetings to keep everyone up to date with goings on across the company and introduce new joiners.
We believe that we are in the process of successfully building a company that people enjoy working for. Our employees should feel valued, supported, and fulfilled. We know that there’s always more that we could be doing and have regular conversations about what we can improve. Everyone’s opinion is important and all input is taken on board.
