• Influence architecture and technical decisions from day one
• Work independently while syncing regularly with the Vienna and US-based teams
• Participate in occasional in-person meetings in Vienna

• Solid understanding of PostgreSQL and backend best practices
• Proven experience building and shipping full stack applications end-to-end
• Excellent communication skills in English (German is a plus)
