Senior Mobile Engineer

Mobile at Kraken

We’re building an innovative mobile platform to scale inline with Kraken’s growing client base, with flexible solutions to meet the needs of customers across multiple utilities. Kraken is a disruptor in the energy sector, the capabilities we offer are helping to drive the transition to a cleaner energy system, as a mobile team we aim to build first in class mobile solutions to support those goals. 

Kraken is in a period of rapid growth, bringing huge opportunities for the right person to be involved in projects with organisational level impact. We’re building a team to work fluently, move fast, and make a tangible difference in energy tech and beyond. Our current projects span electric vehicles, energy retail, smart home device management, heat pumps, and more. Our projects are ambitious and seek to help Kraken’s clients such as Octopus Energy, their customers, and the clean energy transition.

Our Team

We launched the new Octopus Energy app with a small team of 4 engineers, product, and design in 2021. Since then we’ve grown to multiple cross-functional teams, 20+ mobile engineers, and serve over three million monthly active customers in 8 different countries, and a growing number of client apps across multiple utilities. 

We’re expanding to meet the challenges of rolling out a single platform which supports diverse utility markets around the world. Every team member helps define culture and processes necessary to work collaboratively and effectively across multiple product teams, whilst instilling good engineering practices for the team as a whole.

Our Technology

As an organisation we like to move quickly. This is true both in how we operate as a business and the technology choices we make. We were very early adopters of Kotlin Multiplatform (KMP) and used the technology when it was in pre-alpha, at scale, to great success. It helps us share code across Android and iOS without the user experience tradeoffs.

KMP was officially released in late 2023 so we don’t expect our applicants to have experience using it. It powers the extensive shared layer across our Android and iOS apps, with UI powered by Jetpack Compose and SwiftUI. Our app is built around offline-first reactive patterns and utilises unidirectional data flow with a layered architecture. Our view models are written using Jetpack Compose and compliment our state driven UI.

We release updates to customers weekly. We gain release confidence with our suite of automation and unit tests running in CI (GitHub Actions), and configure features remotely using feature flags.

• You’ll be involved in the platform team efforts to scale what we can do in mobile, enabling feature teams to be unencumbered by tooling, spend less time in incidents, and enjoy working in the codebase.
• This is achieved through tooling improvements, greater testing automation, and providing regular quality of life improvements.

• You’ll be someone who appreciates the impact a nimble team can make on customers and clean energy.
• Your passion for clean energy and sustainability will help provide context on your everyday work.
• You will thrive with us if you can effectively communicate with coworkers in different timezones.
• You’ll enjoy contributing across the whole development process including design and product.
• Experience as an iOS/Swift developer (commercial or open source), with a desire to work across both iOS and Android using Kotlin.
• Proven experience leading technical projects or initiatives
• Finally, you’re interested in staying on top of upcoming technologies that could benefit our team.
