Activities
We are seeking a Lead Software Engineer to drive a major transformation program within our Gas & Power Trading IT team. This role sits at the core of a strategic initiative to decommission a legacy in-house gas nomination platform and build a robust, scalable in-house ETRM solution aligned with future business needs. You will not only contribute to development but also lead the technical transformation-defining, designing, and building a sustainable target system while ensuring a smooth transition away from legacy platforms. This position requires deep technical leadership, strong architectural vision, and the ability to guide teams through complex system modernization efforts.

Establish development standards, best practices, and design principles.
Bridge the gap between business needs and technical solutions.
Ensure Business Continuity

Prioritize delivery to balance short-term operational needs with long-term strategy.
Collaborate Globally
Partner with Gas Operations teams to understand business priorities.
Coordinate with global IT teams (US & Europe) to ensure alignment and avoid duplication.
Work closely with Business Analysts, product stakeholders, and leadership.

Accountabilities
Deliver tactical and strategic evolutions or fixes on projects with significant impact on business profitability, in alignment with business constraints. Guarantee the reliability, quality, and security of all implemented changes, ensuring full compliance with internal development standards and the framework defined by or with the Architecture Committee .
Candidate Profile
7+ years of experience in software engineering with strong backend expertise in the .NET framework and C#.
