Senior Data Scientist

Om jobbet

What We Do Flower is Flexible Power. We are a next-gen energy company leveraging AI and machine learning to make renewable energy stable and always available - even when the sun isn't shining and the wind isn't blowing.

Through smart optimization and trading of energy assets like wind and solar farms, battery systems, and EV chargers, we make renewable energy reliable and predictable, leading the charge towards the energy system of tomorrow.

Who We Are Tech company at heart. Purpose-driven at core. Flower consists of a diverse group of innovative individuals with a strong desire to improve the state of the world.

At Flower, we believe trust, collaboration and diversity are essential to not only create an inclusive work environment, but also drive career growth. By embracing varying perspectives, we allow creativity and progress to flourish.

To accelerate towards our goal of becoming the pioneering force powering the energy system of tomorrow, we are now looking for a passionate and skilled Senior Data Scientist to join us!

About The Role:

As a Senior Data Scientist, you will shape the foundation of Flower's short-term forecasting capabilities - powering the models that directly drive our daily trading decisions. You will be part of a small, highly skilled team operating at the intersection of data science, energy systems, and close-to-real-time market dynamics.

You will own the full lifecycle of your models - from idea to production - working closely with Data Engineers, Machine Learning Engineers, and Energy Market Experts to ensure our forecasting stack runs smoothly and is continuously improving. This is a hands-on role focussed on time-series modelling, rapid experimentation, and the ability to translate data into high-impact operational decisions.

What You'll Do:

Build & maintain short term operational forecasting models for energy volumes & prices that drive our trading decisions on a day-to-day basis

Build time series models to understand and explain recurring patterns across different measurements, products and regions to distill signals as features for your next model

Prototype quickly: iterate on simple models, validate rigorously, and scale what works in a dynamic market environment

Own the full model lifecycle: EDA, feature engineering, model development, validation, deployment and continuous evaluation, supported by our team of DEs, MLEs & Energy Market Experts

Write your models in Python, version your code in Git, use CI/CD to ensure full reproducibility

Partner with DEs to evaluate and integrate new data sources (weather, grid conditions, market signals)

Collaborate & mentor across other data scientists, quants and engineers.

Who You Are:

5+ years building and deploying ML/time-series models in production

Strong Python + SQL and no stranger to the command line; comfortable writing clean, maintainable, production-ready code

Deep understanding of time-series forecasting and real-world modeling challenges

Curious, data-driven, and comfortable working with messy or complex datasets

Able to take projects from idea to production autonomously

Highly driven by our mission and your impact, yet humble enough to know we are all always learning

Thrive in a fast-moving environment and adapt models as markets evolve

(Bonus) Experience in energy markets, trading, or power systems - or demonstrated motivation to learn
