Software Delivery & Operations Architect (H/F)

Context & Environment

Integrated Power Modelling (IPM), in OneTech Technical Line Power, supports the company’s technological ambitionin the digitalization of renewable energies value chain. It brings together cross‑domain expertise (scientific and digital) to deliver digital products with the goal of maximizing both the performance and value of renewable assets (solar, wind,energy storage).

It is built around four platforms, each oriented toward internal business clients (GRP, REN, FPI, Trading, etc.): Origination & Design, Grid Integration, Operations Performance & Optimization, and Forecasting. Each platform isstructured into three teams: Product Solutions (PS), Research & Capability Development (RCD) and Software Delivery& Operations (SDO).

The Operations Performance & Optimization platform’s products focus on operational efficiency and the optimization of assets, with strong Data/Cloud integration and Machine Learning/Optimisation orientation.

As Software architect, you will operate in the SDO team, and interact in close collaboration with Product Managers (inPS), Product Owners (in SDO) and RCD team, as well as with entities out of IPM (eg Digital Line, IT Department,Innovation Accelerator, TTE On…)
