In a rapidly evolving payments landscape, Estreem positions itself as a disruptive player, combining best-in-class security, technological agility, and economic competitiveness. The objective is straightforward: to quickly rank among the top three payment processors in Europe. 

Estreem’s three “E’s” capture its DNA: technological Excellence, deep industry Expertise, and a strong European vision.

📋 Your role and key responsibilities

Attached to the Product Department, you will be responsible for the complete transformation of Estreem’s technical documentation by adopting a docs-as-a-product approach. Your role will be to define and drive the documentation strategy (vision, standards, governance, and information architecture), rethink the existing documentation (currently living exclusively within the Office suite) and lead the transition toward product-oriented documentation.

Tldr: You’ll take on a large set of legacy documentation and transform it into a clean, scalable, product-grade documentation system. This role is ideal for someone who thrives on big challenges, isn’t afraid of complexity, and is motivated by bringing clarity and structure to evolving systems.
