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.
