ABOUT THE ROLE

Join the technical customer-success team at a fast-growing, Y Combinator-backed AI voice SaaS startup headquartered in Berlin. As a Customer Engineer, you'll sit at the intersection of product, engineering, and customers — ensuring successful adoption of the platform, resolving technical challenges, and translating real-world customer needs into meaningful product improvements. Your work will have a direct impact on customer satisfaction and the broader mission of automating customer call operations at scale.

WHAT YOU'LL DO

  • Provide hands-on technical guidance to help customers deploy, configure, and optimize the platform for their specific use cases.
  • Troubleshoot PostgreSQL-backed data workflows and full-stack code (TypeScript, React, Node.js, Python) alongside customers.
  • Support customers in building effective prompting strategies and AI agent workflows to unlock maximum value from the product.
  • Build and maintain strong, trust-based customer relationships, acting as the primary technical liaison between customers and internal product/engineering teams.
  • Gather, synthesize, and communicate customer feedback to drive product improvements, documentation, and roadmap decisions.

WHAT WE'RE LOOKING FOR

Required

  • 2+ years of Software Engineering experience with demonstrated, direct business impact through written code.
  • Solid experience with TypeScript, React, Node.js, and Python.
  • Familiarity with PostgreSQL, including troubleshooting data workflows.
  • Experience in a customer-facing capacity — technical support, solutions engineering, developer relations, or similar.
  • Ability to help customers with prompting techniques and AI agent workflows.
  • Excellent written and verbal communication skills; comfortable serving as a bridge between technical and non-technical stakeholders.

Nice to Have

  • Strong computer science fundamentals.
  • Prior experience in B2C SaaS, conversational AI, or voice automation products.
  • Genuine curiosity and enthusiasm for AI/LLM-driven products.
  • A pragmatic, ship-fast mindset and comfort operating in a small, high-velocity team.

LOCATION & WORK ARRANGEMENT

This role is on-site in Berlin, Germany. Visa sponsorship is available for the right candidate.

WHY JOIN

  • Work at the frontier of AI voice automation — a category with enormous market momentum.
  • Backed by Y Combinator and leading European investors (Seed stage).
  • Small team (under 50 people), meaning your contributions shape both the product and company culture directly.
  • Close collaboration with founders and senior engineers on problems that matter to real enterprise customers.
