Staff Software Engineer

Berlin | Hybrid Working | Sustainability Technology

Technology creates the biggest impact when it's closely aligned with product vision. We're looking for a Staff Software Engineer who wants to shape both.

Our client is a leading technology company in the sustainability space, helping organisations make smarter, more responsible decisions through innovative software. As they continue to scale, they're investing in the next generation of their platform and are looking for an experienced technical leader to own a strategic product domain and help define its future.

This is not a role focused solely on delivery.

It's an opportunity to become the technical and architectural authority for a critical area of the platform, partnering with Product, Engineering Leadership and business stakeholders to influence what gets built, how it gets built, and where the product evolves next.
