Kraken is the technology tentacle of the Octopus Energy Group.
Octopus are not your average energy supplier and we’re not your average mobile team. Work here is different; the global tech team is aligned on a single mission, to bring cheap green energy to the masses and provide outstanding service to customers who join us for the ride.
Life here is truly diverse, you’ll get the chance to work on BLE hardware integration and controls for our Octopus Heatpump, EV and home battery control through our Intelligent Octopus tariff, energy account management and work with non octopus clients, including other utilities like water and broadband.
To deliver such a wide range of features we split mobile engineering into four distinct sub teams; Devices, Intelligent Octopus, OE Mobile and Client, as a member of one of these teams you’ll work closely with your tech lead and product manager as well as backend engineers and designers. We like our engineers to be product focused so we don’t create bottlenecks between product teams and engineering, you’ll be able to work autonomously on your features without requiring sign off for every decision.
How do we work?
We’ve got an important, urgent mission to bring affordable, green energy to the world, and every person at Octopus works relentlessly to make that change happen fast. We work with freedom and responsibility. You'll get a lot of trust to run with ideas and take ownership of what you do.
Our founder Greg has a theory that building a great team should be like building a dry-stone wall: rather than forcing people into 'cuboids' and sticking them together in neat little rows, we take authentic humans, and find ways for them to fit together naturally to form a truly solid team full of unique perspectives and strengths. This way of working isn't for everyone. You have to drive your own work forward; be agile, flexible, and personally accountable for everything you do, from idea to conception. Through this though, you gain a true sense of ownership over the problems you’re solving, and the satisfaction of helping and supporting the millions of people who use what you make.
Our Technology
If you’ve got this far you’ll have noticed a theme of moving quickly, we double down on that notion in our technology choices.
At Octopus we use Kotlin Multiplatform to write a shared layer in Kotlin and build native Jetpack Compose and SwiftUI on top, this has a few benefits:
- Write everything up to the ViewModel once (including tests!), drastically reducing the time to ship new features
- Fix it once fix it everywhereFully native Kotlin and Swift means we get to hire fully native engineers
- Fully native UI means we don’t sacrifice UI and UX, and get access to the latest and greatest platform tools/frameworks as soon as they’ve available
We’ve had great success with this approach and successfully onboarded a mix of native Android and iOS engineers onto the project. You can learn more about how we use Kotlin Multiplatform in our team by watching this talk given recently at our London office.
