Customer Engineer
About the Role
We're a fast-growing, seed-funded AI voice platform helping B2C businesses automate millions of customer calls through human-like AI agents. Our platform spans sales, support, and operational use cases — and we're looking for a Customer Engineer to join our technical customer-success team in Berlin.
In this role, you'll sit at the intersection of engineering and customer success — ensuring customers successfully deploy and get maximum value from our platform, while feeding real-world insights back into our product and engineering teams. You'll have direct, measurable impact on customer satisfaction and on how our technology evolves.
What You'll Do
Provide hands-on technical guidance to customers deploying, configuring, and optimising our platform.
Troubleshoot PostgreSQL-backed data workflows and frontend/backend code (TypeScript, React, Node.js, Python) alongside customers.
Help customers design and refine prompting strategies and related AI workflows to unlock the full value of the platform.
Build and maintain strong, trust-based relationships with customers, acting as their primary technical liaison into product and engineering.
Gather, synthesise, and communicate customer feedback to drive product improvements and documentation updates.

Required:
2+ years of software engineering experience with demonstrable business impact through written code.
Solid familiarity with TypeScript, React, Node.js, and Python.
Hands-on experience with PostgreSQL, including troubleshooting data workflows.
Experience in a customer-facing role — you know how to listen, communicate clearly, and build credibility with technical stakeholders.
Ability to guide customers through prompting, AI workflow design, and related problem-solving.
Excellent written and verbal communication skills; comfortable bridging customer needs and engineering context.
Nice to have:
Strong computer science fundamentals.
Prior experience deploying or configuring SaaS or AI platforms for enterprise customers.
Genuine interest in AI, LLMs, and voice technology.
Location & Work Arrangement
On-site in Berlin, Germany.
Visa sponsorship is available.

Early-stage, high-growth team (~16 people) backed by top-tier investors including Y Combinator.
Seed-stage company with meaningful runway and strong investor backing (Series A/B trajectory).
Work directly with founders and engineers — your impact is immediate and visible.
A role that blends technical depth with customer empathy at the frontier of AI voice technology.
