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.
