Job description
About Us

Since its launch in 2018, Gener8 has been at the forefront of the “open data” movement: the belief that people should be able to control and be rewarded from their own data. Gener8’s consumer products include a web browser, browser extension, IOS and Android apps. Our products enable people to transparently and willingly share their data with Gener8, whilst preserving their privacy, so that we can create value from it for them.

We are growing fast. With tens of thousands new app downloads every month. Every month our desktop browser racks up the equivalent of 250 yrs in time spent browsing on it. As you can imagine, we have huge amounts of proprietary data which we can create value from.

Gener8 was named ‘Disruptor of the year’ in 2022 by the Great British Entrepreneur Awards. Our investors include 3 Dragons from BBC’s Dragon’s Den as well as personalities such as the rap star Tinie Tempah, former football manager Harry Redknapp and cricketer Chris Gayle to name a few. In 2023 we met with the Prime Minister at Downing street and were invited to become a member of the Government’s new “Smart Data Council”, shaping the future of data legislation in the UK. We also regularly engage with European legislators on the Digital Markets Act which empowers users to control and earn from their data.

About The Role

You’ll be working on our core consumer web products across desktop and mobile, with your work at the very front of the interactions our users have with our product every day.

  • Creating a new onboarding flow for our desktop browser extension
  • Adding new data sources that allow users to earn from their data
  • Working on our rewards platform where users can exchange their earnings for real life rewards

Our web products use React, Next.js and plenty of good old Vanilla JS. On the backend we use Golang to serve RESTful and gRPC APIs running on Kubernetes. We use GitHub for CI and version control, Jira for tracking tasks and Slack for sending cat GIFs.

Responsibilities
  • Being hands on with development of our website, extensions and admin
  • Developing new features, modifying existing ones and fixing bugs as they arise
  • Writing automated tests to keep the quality of our products high
  • Working closely with our app engineers to deliver integrated product features
  • Work closely with the product team to refine new features and user interfaces
Requirements
  • 5+ years commercial frontend web development experience using React
  • A strong grasp of CSS and JavaScript fundamentals
  • Experience making API driven web apps in production environmentsExperience building UIs that surprise and delight users
  • Excellent verbal and written English communication skills
  • British citizenship or a pre-existing right to work in the UK
Benefits
  • 🚀 Part of a fast growing company where you will have real responsibility and autonomy
  • 💻 Your choice of computer hardware
  • 💰 Annual training and conference budget
  • ⛳️ Regular team days out
  • 💥 Your chance to work on a meaningful product that can impact millions of people
