Business Analyst CMS - Brussels - Energy Sector - ASAP Start - Freelance / CDI

Are you interested in contributing to the transformation of the Belgian and European energy landscape?

You will join a major player operating within the energy and utilities domain, active at national and European level, and responsible for ensuring a reliable, sustainable, and future‑oriented electricity supply.

Working alongside internal teams and other external consultants, you will contribute to building a green, resilient energy infrastructure that supports economic growth while reducing environmental impact.

The organisation strongly believes that diversity and inclusion are key drivers of innovation, creativity, and performance. Collaboration and shared responsibility are central to achieving meaningful, long‑term impact.

As a Senior Business Analyst, you act as the bridge between business stakeholders and IT teams, ensuring that business needs are translated into effective and high‑quality technical solutions.

You analyse business processes, structure information, gather and validate requirements, and support solution implementation in an Agile environment. You bring a continuous improvement mindset: curious, respectfully critical, and unwilling to accept “we’ve always done it this way.”

You challenge assumptions constructively and collaborate closely with stakeholders to design future‑ready, value‑driven processes aligned with the organisation’s business architecture.
