As a Data Scientist at Schneider Electric, your day-to-day work is highly collaborative and directly tied to the lifecycle of intelligent energy products. You will not work in a silo; instead, you will act as a bridge between physical engineering and digital systems.

Your primary responsibility will be designing, training, and deploying machine learning models that analyze massive datasets generated by smart devices, factories, and commercial buildings. You will write clean, modular, and production-grade code to ensure these models can run reliably at scale, whether in the cloud or directly on edge devices within industrial plants.

Collaboration is a core component of this role. You will partner closely with:

• Domain Engineers (such as electrical, mechanical, and power engineers) to understand the physical constraints of the systems you are modeling.
• Data Engineers to build robust data pipelines that clean and ingest massive streams of IoT data.
• Product Managers to define key performance indicators and ensure your models solve actual customer pain points.

Ultimately, your goal is to turn raw, complex physical data into automated actions that reduce energy waste, lower carbon emissions, and predict equipment failures before they happen.

While the exact requirements can vary depending on the specific team and seniority level, Schneider Electric looks for a balanced mix of software engineering discipline, statistical depth, and domain curiosity.

• Technical Skills – Proficiency in Python or R, with a strong preference for Python due to its production capabilities. Deep familiarity with libraries such as Pandas, NumPy, Scikit-Learn, and frameworks like TensorFlow or PyTorch. Strong SQL skills are mandatory for data extraction and manipulation.
• Experience Level – Typically, a minimum of 2–5 years of professional experience as a Data Scientist or in a highly quantitative analytical role. Experience working with time-series data, IoT datasets, or industrial systems is highly valued.
• Soft Skills – Excellent communication skills with the ability to explain complex technical concepts to non-technical stakeholders. A proactive, curious mindset with a passion for sustainability and green technology.
