• Comfort working with numbers/Excel and multiple online sales platforms; prior bookkeeping-adjacent experience is a strong plus (full accounting qualification not required)
• Strong organisational skills and reliability with deadline-driven monthly tasks
• Warm and precise communication with fluency in German and business level English
• Strong problem solving skills - we require someone who relishes the challenge of making the figures balance
• Process driven with the ability to see mundane tasks through to their completion
• Experience with tools like Brightpearl (ERP), Shopify, Amazon is a bonus (training provided).

Most importantly: you're trustworthy, reliable, and bring a strong teamwork attitude. We're a close-knit team and we value culture fit greatly.

Here’s our offer:

• Competitive salary
