Excellent written and verbal communication skills; comfortable bridging customer needs and engineering context. Nice to have: Strong computer science fundamentals. Prior experience deploying or configuring SaaS or AI platforms for enterprise customers. Genuine interest in AI, LLMs, and voice technology. Location & Work Arrangement On-site in Berlin, Germany.
