About
Kraken powers some of the most innovative global developments in energy. We’re a technology company focused on creating a smart, sustainable energy system. From optimising renewable generation, creating a more intelligent grid and enabling utilities to provide excellent customer experiences, our operating system for energy is transforming the industry around the world in a way that benefits everyone.
It’s a really exciting time in energy. Help us make a real impact on shaping a better, more sustainable future.
The role This is a hands-on, delivery-focused ML engineering role. You’ll join a team working on mature, live products where the priority is shipping, improving, and maintaining features. While the role is ML-focused, our ML engineers work very close to the software layer so being comfortable with production Python code, databases, and systems is essential. You’ll initially focus on the Companion product, a RAG based chatbot, supporting feature delivery, maintenance, and incremental improvements, while collaborating closely with product managers and engineers across Kraken.
What you'll do
Design, build, and improve machine learning and GenAI-powered features used in live production systems
Deliver consistent, high-quality work each sprint (typically 2–3 smaller tickets or 1 larger piece of work per two-week sprint)
Work with product managers to clarify requirements and translate them into robust technical solutions
Write clean, maintainable Python code and contribute to shared codebases used across ML teams
Analyse data, evaluate approaches, and iterate on solutions based on real-world usage
Collaborate with other ML engineers and software engineers across Kraken when working on shared systems
Ask questions early, seek clarification when needed, and contribute ideas during team discussions
Participate in sprint planning, stand-ups, and knowledge-sharing sessions
While our current products are largely GenAI-based and do not train models, a strong grounding in ML fundamentals is still important as the platform continues to evolve.
What you'll need
A solid foundation in machine learning fundamentals, including data analysis, model evaluation, and ML pipelines
Strong experience with Python and SQL in a production environment
Comfort working in software-engineering-heavy ML roles (this is not a research-only position)
Experience working with real-world systems where reliability, readability, and maintainability matter
Confidence asking questions, collaborating across teams, and explaining your thinking
Ability to work independently on defined tasks and see them through to completion
Experience with the following is a bonus:
Exposure to GenAI / LLM-based systems (e.g. prompting, orchestration, evaluation)
Familiarity with cloud environments (especially AWS)
Experience with tools such as Databricks, Datadog, or similar data / observability platforms
Awareness of ML libraries such as PyTorch, TensorFlow, or Hugging Face (even if not used day-to-day)
Ways of working
Two-week sprints with planning and retrospectives
Asynchronous-first communication with daily stand-ups
Regular knowledge-sharing sessions
A no-blame culture with high trust and autonomy
Flexible hybrid working, with in-person collaboration typically on Tuesdays and Thursdays
We would prefer someone who can work in our London office on a hybrid remote policy of 1-2 days a week onsite. You do need to be able to work in the UK.
