Customer Engineer

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.
