Responsibilities

• Frame strategy before it becomes a project. You'll be the first to tackle new strategic topics, structure questions, run initial analyses, and provide direction to the founders.

• Writing that doesn't need editing. Clear and direct communication in investor updates, candidate emails, and partnership briefs.
• Technical curiosity. Understanding of software development and ability to engage with engineers.
• Fluent English. Proficiency in English as our working language.

Nice to Have
