Tray.io | London | Backend Engineer (Scala/Java) / Security Engineer / Frontend Engineer | Full-time | Onsite | https://tray.io Tray is a visual programming platform. It’s a low-code user experience that allows anyone to build business logic that precisely defines how data flows through their organisation. We’re a well-funded startup with a team in San Francisco and 100+ in our London Engineering HQ. We have secured a huge Series C in November this year, at over 8.5x the valuation of our Series A in March 2018; we’ve worked hard on creating a fantastic support layer for our technical teams and now we’re expanding. We’re small (approaching medium sized) and dynamic, very open to new ideas and the work you do now will have a big impact on shaping how we grow our team and our product. We aim to pick the right tool for the job, and currently use: Typescript, React, Redux, GraphQL, and our toolchain includes Webpack and PostCSS. On the backend, our APIs are built in Scala, with Go and Java powering some of our custom services. We are excited by people who want to constantly innovate; borrow from other industries, experiment with new tools and pool their knowledge with other solution seekers; people who have shipped entire projects with ownership and autonomy; people who take pride in what gets built, all the whilst balancing day-to-day pragmatism with building for the future.
