Context of the Supply Portfolio Management (SPM) – Strategic Importance

SPM plays a vital role in modeling and hedging energy risks for client portfolios. The function is evolving from locally fragmented teams to a more centralized, harmonized approach. Key transformation initiatives include:

Establishing a central SPM entity to develop consistent methods and tools

Building a collaborative, cross-geography SPM community

Supporting career growth for portfolio managers

Promoting best practices and unified risk representation

Implementing scalable, automated systems for improved forecasting, pricing, and contract management

Our teams are committed to fostering a culture of collaboration, knowledge sharing, and continual improvement, ensuring both global alignment and local value creation for ENGIE’s clients and stakeholders.

Within SPM the transversal domain TrueWatts is in charge of:

gathering people in charge of actuals consumption management

sharing good practice

build expertise on data modeling and grid error management

design the MPD features and support its deployment (MDP is the product in charge of metering data management in Engie)

This domain is composed of several operational Middle Offices, in charge of certifying the actuals (balancing and billing volumes) for all Supply processes, leveraging the use of MDP.

Additionally, the core product team is the small data science team in charge of designing the core features that will be industrialized by MDP IT teams. The features support all the grid data imperfections: holes in timeseries, inconsistencies between sources, etc. From the detection of inconsistency patterns to the correction algorithm, this team is charge of settling the common framework use through all the B2B countries.

About the TrueWatts Team within SPM

The TrueWatts domain is a dynamic and cross-functional teams at the heart of Supply Portfolio Management (SPM), dedicated to delivering excellence in actual consumption management. Our mission is to bring together experts of dedicated Middle Offices to certify actual consumption volumes—balancing and billing—for every Supply process.

The TrueWatts domain plays a pivotal role in designing and deploying the MPD (Bee Stone metering data management product) for ENGIE. We support its implementation by developing innovative features and ensuring best practices are shared across all operational Middle Offices, making full use of MPD’s capabilities.

At the core of TrueWatts is a focused data science team that creates and refines the foundational algorithms powering the MPD curation pack. We tackle challenges such as gaps in time series data, inconsistencies between sources, and grid data imperfections. Our work ranges from detecting patterns of inconsistency to building correction algorithms, establishing a robust framework that is applied across all ENGIE’s B2B operations worldwide.

Joining TrueWatts means being part of an innovative and collaborative environment, where your contributions will directly drive the energy data reliability and help shape green and competitive offers. If you’re excited by solving complex data challenges and making a real impact on the energy sector, the TrueWatts domain is the place for you.

Role:

As senior data scientist in the core business team of the TrueWatts domain, you will:

Identify and analyze patterns of inconsistencies across the various available data sources.

Develop and implement algorithms to correct detected inconsistencies.

Design and deploy operational quality monitoring dashboards for use by Middle Offices.
