• Use AI tools to increase efficiency, while ensuring content is accurate, clear, and human.
• Collaborate with Product, Engineering, Design, Marketing, CX, and Implementation teams.
• Manage the lifecycle of your content, from writing to publication, and then track its performance via dashboards.
• Propose improvements to documentation processes and tools.

Requirements

• Minimum 3 years in technical writing.
• Mastery of Git and Markdown/MDX, with real experience in docs-as-code.
• Experience migrating content between frameworks is a major plus (Docusaurus, Mintlify, GitBook, Zendesk.).
• Excellent writing skills: you know how to self-edit and proofread others' work.
• Ability to understand and simplify technical subjects (API, payments, banking).
• Good accessibility and localization practices.
• Fluent English is essential.
• Autonomous, fast, and comfortable managing multiple projects in parallel.
