All our technology is written and maintained by a multi-discipline engineering team of around 600 people globally. Our engineers work in ‘super teams’ which are focused on key areas of our platform as well as other innovative products. This also includes server-side, client-side and mobile engineers working closely with UX experts, copywriters and designers.

Teams are empowered to choose a way of working that works for them, often opting for a Kanban-like approach. Notion and Asana are then used to specify and manage work; Github, CircleCI and Terraform Enterprise as part of an immutable-infrastructure, continuous delivery pipeline; and Datadog, Sentry and Cloudwatch to measure performance and monitor production.

We’re now charging Kraken to power utilities beyond energy (think water, broadband,..) and have created a new business Kraken Utilities. We are building an innovation (ML/Data/AI) team from scratch and are looking for a Machine Learning Engineer to join and help us scale, implement a good culture, and work on some really exciting tech challenges.

You'll join a small team working on research around how to help prevent water leakage (think domestic water usage trends, leak detection software, smart meter data trends etc). You'll also get the chance to work on Natural Language Processing (NLP) and Large Language Models (LLMs) to build things like message generating systems.

Some of our coding conventions are open-source .

Kraken is a great place to learn, work with some talented engineers and level-up your skills.
