Senior Applied Data Science Engineer (f/m/d) (m/w/d)

A Snapshot of Your Day
As a Senior Applied Data Science Engineer within the Scalable Core team, you will lead the design and implementation of intelligent solutions that drive the digital transformation of energy management. You'll apply advanced data science techniques to real-world problems, guide the development of reusable components for our AI/ML/GenAI platform, and ensure that deployed models are robust, scalable, and production-ready. Beyond technical contributions, you will play a key role in shaping the platform's roadmap, mentoring junior team members, and aligning our work with strategic goals. Your impact will be felt across the Siemens Energy as you help engineering teams create high-quality, intelligent, and scalable software solutions for cloud, on-premises, and edge environments.
How You'll Make an Impact

• Apply classical data science techniques to complex energy datasets to extract insights and deliver predictive solutions.
• Design and implement reusable modules for preprocessing, feature engineering, and model evaluation within our AI/ML platform.
• Lead integration of models into production pipelines in collaboration with MLOps engineers.
• Drive model lifecycle processes including explainability, uncertainty estimation, and SLA validation.
• Guide junior engineers, structure the team backlog, and ensure alignment with overall strategy and priorities.
• Communicate with technical and non-technical stakeholders, including executives, to align on goals and present results.

What You Bring

• Master's degree in Data Science, Computer Science, Applied Mathematics, or a related field.
• Solid longstanding hands-on experience in applied data science or statistical modeling, with strong practical outcomes.
• Advanced proficiency in Python and its data science ecosystem (e.g., pandas, scikit-learn, NumPy) and familiarity with deep learning frameworks such as PyTorch or TensorFlow.
• Strong understanding of model evaluation, statistical analysis, and production deployment, including experience with MLOps tools like MLflow, Airflow, or Kubeflow across cloud, on-prem, and edge environments.
• Proven ability to lead, coach, and collaborate effectively within a cross-functional team, with excellent communication and stakeholder management skills.
• Experience working with large language models (LLMs) or generative AI systems is a plus
