Kraken technologies
Kraken Technologies is a company within Octopus Energy Group who are licensing the Kraken platform and operating model to clients across the world. Current clients are both the Octopus Energy retails businesses around the world as well as external clients such as Good Energy, Origin, EDF, E.ON & Queensland Energy - with many more expected to join over the next few years!
Our product team - Siphon - builds a core technology that allows the overall Kraken platform to interact with other utilities.
Our technology
The Siphon team’s cloud-native services have a strong code-as-infrastructure backbone, and we use both Kubernetes and Terraform configuration files to manage all of the hosted artefacts. We enable CI/CD with GitHub Actions. Engineers are encouraged to learn and extend our DevOps stack.
Our backend stack is a series of microservices written in purely functional Scala using the Cats Effect libraries (https://typelevel.org/cats-effect/): Http4s for the web host, fs2 for streaming, and Doobie for database access. The systems we maintain have extremely strict zero-downtime requirements, and we find this paradigm and set of technology choices give us the most resilient, type-safe, scaleable, and error-free software the fastest.
We use Python for most data manipulation, and have sophisticated tooling to make sure it blends beautifully with our Scala microservices.
We see data as the ‘hub of the wheel’ of everything we do, and use Apache Kafka extensively. All our microservices interact directly and indirectly with Kafka, shuttling data between services, as well as producing and consuming data events via Kafka streams.
