About the Role

We're a fast-growing, Y Combinator–backed AI voice platform (Seed stage) helping B2C companies automate their customer call operations — from sales and lead qualification to support and scheduling — across millions of calls and 30+ languages. Our small but mighty team (11–50 people) is based in Berlin, and we're looking for a Customer Engineer to join our technical customer-success function.

In this role, you'll sit at the intersection of engineering, product, and customers. You'll be a trusted technical partner to the businesses adopting our platform, helping them get real value quickly — and feeding their insights back into what we build. This role has a direct, measurable impact on customer satisfaction and the real-world performance of our AI technology.

What You'll Do

  • Provide hands-on technical guidance to customers as they deploy, configure, and optimise our platform for their specific use cases.

  • Troubleshoot Postgres-backed data workflows and frontend/backend code (TypeScript, React, Node, Python) alongside customers.

  • Help customers design and refine prompting and AI agent workflows to unlock maximum value from the platform.

  • Build and maintain strong customer relationships, acting as the primary technical liaison between customers and our product/engineering teams.

  • Gather, synthesise, and communicate customer feedback to drive product improvements, documentation, and roadmap decisions.

What We're Looking For

Must-haves:

  • 2+ years of Software Engineering experience with demonstrable business impact through written code.

  • Solid familiarity with PostgreSQL and comfort troubleshooting data workflows.

  • Hands-on experience with TypeScript, React, Node.js, and Python.

  • Some form of customer-facing experience — whether in a support, solutions engineering, or consulting capacity.

  • Ability to help customers craft and iterate on prompts and AI agent configurations (prompt engineering / social engineering mindset).

Nice-to-haves:

  • Strong CS fundamentals.

  • Genuine interest in AI, LLMs, and conversational AI products.

  • Experience in B2C SaaS, CRM integrations (Salesforce, HubSpot), or telephony/voice platforms.

  • A pragmatic, ship-fast mindset — you prefer iterating quickly over waiting for perfection.

Location & Work Arrangement

  • On-site in Berlin, Germany.

  • Visa sponsorship is available.

Why Join

  • Work at the cutting edge of conversational AI and voice automation.

  • Direct influence on product direction through close customer collaboration.

  • Small, high-calibre team with a fast-moving, low-bureaucracy culture.

  • Backed by top-tier investors at the Seed stage — early enough to matter, funded enough to build.
