We pioneered the Organic SolidFlow battery

CMBlu Energy is on an exciting journey towards becoming a global cleantech company. Our mission is to enable unlimited energy storage modelled on nature - for everyone, worldwide.   

What are SolidFlow batteries?    

SolidFlow batteries store energy in organic molecules. The absence of explosive materials makes them safe, the use of socially and ecologically conflict-free raw materials makes them sustainable and the almost unlimited availability of materials makes them scalable and cheap to procure. This makes our patented SolidFlow technology a game changer in the development of a global climate-neutral energy system.   

From start-up to scale-up: we're tackling it together    

CMBlu Energy is developing from a start-up focussing on research into a manufacturing scale-up that is on its way to series production. Around 240 employees are working towards this goal at CMBlu Energy. Our head office is in Alzenau near Frankfurt, with a branch office in Obernburg. There are also subsidiaries in Athens, Greece and Petaluma, USA.    

 Your Mission

As a Senior Data Engineer (m/f/d), you play a key role in shaping our cloud-based data platform and ensuring that data from research, pilot lines, and production flows together efficiently.
Together with our R&D teams, you transform heterogeneous measurement, process, and metadata into high-quality, reliable, and well-structured information.
With us, you won't spend your days building reports – you make data-driven development possible from early research through pilot lines to production.

Your Responsibilities
  • Design data architectures and models based on Azure services such as Databricks, Data Factory, Event Hubs/Event Grid, and Data Lake.
  • Develop and operate scalable pipelines for measurement, process, and metadata from laboratories, test benches, prototypes, and production equipment.
  • Prepare data according to the Bronze/Silver/Gold architecture so that it can be directly used by domain teams for analyses and evaluations.
  • Ensure data correctness, completeness, and reliability through validations, plausibility checks, and quality controls.
  • Develop interfaces and services to deliver processed data to internal systems such as LIMS.
  • Support R&D teams in analyzing and further processing their data.
Your Profile
  • You hold a degree in Computer Science, Data Engineering, Data Science, or a comparable field.
  • You bring extensive experience with Python and PySpark and can implement complex data processing workflows.
  • You are highly proficient in Databricks and have worked with modern components such as Asset Bundles, Delta Live Tables (DLT), Lakeflow Declarative Pipelines, and Databricks Apps.
  • You have practical experience with the Azure Data Engineering stack — particularly Data Factory, ADLS Gen2, and Event Hubs — and in building batch and streaming pipelines.
  • You are familiar with CI/CD using GitLab and ideally have experience with Terraform, Docker, and Kubernetes (AKS).
  • For you, electricity doesn't just "come out of the socket" – you have a basic understanding of how electrical or battery-related measurement concepts fit together.
  • Very good English and German language skills complete your profile.

Our Benefits at CMBlu Energy AG for You:

  • VSOP Program: With our Virtual Stock Option Program (VSOP), you can be part of the success of CMBlu Energy AG and benefit from the growth of our company.
  • Deutschland-Ticket: We fully cover the cost of a Germany-wide train ticket, allowing you to travel sustainably and comfortably.
  • Meaningful work: Work on the development of our innovative Organic SolidFlow battery, which makes an important contribution to sustainable energy use and storage.
  • Remote Work: Depending on the role, we offer the possibility to work partially remotely, if the position allows.
  • Development Opportunities: We support your personal and professional development through regular training sessions and exciting projects.
  • Fair Pay: We provide a competitive and fair salary that recognizes your performance.
  • Our Values: At CMBlu Energy AG, being reliable, innovative, and relentless is at the core of our collaboration.
