Chief of Staff (m/f/x)

About this role

Responsibilities

• This isn't an administrative or "assistant" role. As Chief of Staff, you are a core member of the leadership orbit. You will work directly with Valentin (Co-Founder) to translate high-level vision into operational reality.
• You will sit at the intersection of Growth, Strategy, Finance, and Operations. Your mission is to tackle the most complex, ambiguous challenges that don’t yet have a home, whether that’s architecting our international expansion, refining our AI-driven unit economics, or managing the machinery of a Series B fundraise.
• This role is a springboard. You will gain a "CEO-level" view of building a category-defining AI company.
• What you’ll do
• Strategic Initiatives: Lead high-impact projects from conception to completion (e.g., designing an AI-era pricing model, spearheading entry into new European markets, or optimizing the sales-to-onboarding funnel).

About Cortea AI

We’re Cortea, a Berlin-based startup rebuilding how audits are done. Audits are still driven by spreadsheets, checklists, and manual reviews in one of the most regulated, high-stakes areas of business. We use AI to automate audits end to end, so highly educated auditors no longer spend 60+ hour weeks on manual work and can focus on judgment, trust, and choices that matter. With €15m+ in funding, a live product, and paying customers across Europe, we’re at a stage where your choices will directly shape Cortea’s future, and how audits are done.
