We’re a fully remote company and use a formula-based salary calculator to determine starting salaries, factoring in location, experience, and responsibility. This approach helps us avoid pay gaps (e.g., gender pay gap) by basing compensation on objective criteria rather than negotiation. Because we apply a location factor, the actual figure for hires outside Cologne will differ from the reference range above, and the total package may include components beyond base salary (e.g., equity, benefits). We’re publishing this range to comply with the EU Pay Transparency Directive. Your recruiter will walk you through how the calculator applies to your location and level.​Salary Range: €50,000 – €80,000
