Kraken is the technology tentacle of the Octopus Energy Group.
Our technology
We build a core technology that allows Octopus Energy to interact with other utilities.
Our 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.
