Job description

This is hybrid role, with two days in our London office every week.

Weʼre looking for a Senior Android Engineer to work on our flagship Kotlin app that is transforming how people control and share their data.

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 IOS and Android apps, a web browser and a browser extension. Our products enable people to transparently share their data with Gener8, whilst preserving their privacy, and to earn rewards in return for doing this.

Today we’re operating in the UK & USA and will be launching in multiple new countries in early 2026.

On the B2B side, the data products that Gener8 creates enables businesses to make faster, smarter decisions. Our customers include some of the world’s largest Big Tech companies, leading ai companies and prominent organisations in finance and ad tech.

About the role

You’ll join the team responsible for major new features in our flagship Android app which helps users better understand their relationship with data and how they can be rewarded from it. This is an exciting opportunity for an individual to make a big impact in a rapidly growing business for a completely new category of product.

Working as part of our existing engineering team, you’ll be actively influencing technical discussions, API designs, and app architecture as we iterate rapidly to deliver great new features to our customers.

Our Android app is completely written in Kotlin. All new features are built using Compose, with any existing XML layouts gradually being replaced with Compose as well. It uses coroutines for threading and is heavily modularised, each feature having its own dedicated module. There's a combination of unit, UI and Integration tests on the project, especially on newer features. We’re also starting to use Kotlin Multiplatform to share code with our iOS app.

This is the right opportunity for you if you have:

• 5+ years commercial experience with Android development
• Strong grasp of the Kotlin language
• Experience using Kotlin Coroutines and Flows
• Experience with automated testing and continuous delivery
• Ability to describe solutions and their architectural tradeoffs
• Excellent verbal and written English communication skills
