About ENGIE and Supply & Energy Management:
ENGIE, a global leader in low-carbon energy and services, relies on its Global Business Unit Supply & Energy Management (GBU S&EM) to provide reliable, sustainable, and affordable energy to all its customers. This strategic unit optimizes the Group’s and clients’ production assets and designs tailored energy solutions for our 200,000 professional clients and 15 million consumers.
The Global Business Unit Supply & Energy Management leverages ENGIE’s assets to deliver secure and sustainable energy to its B2B and B2C customers. It uses its expertise in energy management to provide decarbonized electricity 24/7.
Our Mission & Objectives
- Deliver carbon-free energy to clients around the world, 24/7
- Maximize the value of ENGIE’s diverse assets—including renewables, thermal generation, and storage
- Serve over 15 million residential customers and 200,000 businesses, aiming to reach 550 TWh by 2030 with a growing share of green electricity
- Promote agility, collaboration, and transparency throughout the organization
S&EM is structured around three core pillars:
- OneB2B: Focused on streamlining and scaling ENGIE’s business-to-business solutions across multiple countries
- OneB2C: Dedicated to business-to-consumer operations
- Energy Management: Overseeing the optimization and risk management of energy assets and portfolios
OneB2B – Strategic Focus. As a key pillar, OneB2B drives ENGIE’s B2B strategy by accelerating the delivery of tailored solutions, reducing operational costs, and leveraging unified platforms and shared tools. The team is committed to:
- Speeding up time-to-market for innovative B2B offerings
- Lowering service and build costs
- Developing the Bee-Stone suite—a unified platform that balances global standards with local needs
- Aligning IT and business strategies across geographies
- Implementing agile methodologies and strong governance to support long-term goals
Joining Supply & Energy Management means becoming part of a team of over 10,000 passionate experts spread across 20 countries, all united by a shared mission: shaping a greener and more efficient energy future. Together, we push the boundaries of innovation to deliver decarbonized energy 24/7. Join us and be part of those shaping the energy of tomorrow!
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.
