Team Lead Data Engineering & Analytics (m/w/d)

With a focus on innovation and sustainability, our company is driving forward the expansion of renewable energy infrastructure in order to make a significant contribution to achieving climate neutrality.
By providing energy when it is most needed, we help improve the reliability and efficiency of the power grid while simultaneously reducing CO2 emissions. Equally important to our mission is our AI-based energy trading in the European market, which works hand in hand with our battery storage solutions.
The energy trading unit is responsible for optimizing assets across all markets, balancing renewables, and proprietary trading. We trade short term power algorithmically in an expanding geographical scope and have a highly technical team of veteran software engineers, leading AI experts and power trading professionals.
We are looking for an experienced Team Lead Data Engineer to head our data team (currently ~ 4 engineers) and play a key role in scaling Terra One’s data platform. You will design and implement scalable, efficient data solutions that power our analytics, machine learning models, and trading decisions.
This is a hands-on leadership role that combines technical ownership, architectural direction, and team enablement . You’ll work closely with our ML and trading domain leads to ensure data is reliable, timely, and production-ready across all systems.
If you’re ready to make an impact in the energy transition and shape the backbone of our data infrastructure, we look forward to your application.
