Customer Support Engineer

About The Role

This is a hands-on Customer Support Engineer role at a fast-growing, Y Combinator–backed AI sales automation startup. You'll sit at the intersection of product, engineering, and customers — owning technical issue resolution end-to-end, building AI-powered support tooling, and turning recurring problems into lasting improvements that directly shape the product.

What You'll Do

• Investigate and reproduce production issues spanning product, data, integrations, and workflows.
• Dive into logs, databases, customer examples, and the codebase to identify root causes.
• Own technical resolution end-to-end, including fixing issues directly where possible.
• Communicate clearly with customers to understand problems and ensure they feel supported.
• Design and deploy AI agents that automate customer interactions and accelerate resolution.
• Operate and manage AI agent teams that assist investigation and flag when core engineering input is needed.
• Produce clear technical write-ups for escalations, including reproduction steps and relevant data.
• Document recurring issues, build internal playbooks, and propose product or process improvements.
• Collaborate closely in person with founders, engineering, and product as the company scales.

What We're Looking For

• At least 1 year of full-stack software engineering experience delivering production-grade code.
• Hands-on experience with React, TypeScript, Python, and PostgreSQL in a production environment.
• Demonstrated ability to debug independently across logs, databases, APIs, and unfamiliar codebases.
• Experience owning end-to-end technical customer resolution and communicating issues to non-technical stakeholders.
• Experience designing or deploying AI-assisted support workflows or AI agents.
• Comfortable with customer-facing work and using user conversations to prioritise fixes.
• Structured, reliable, and people-oriented approach to support.
• Experience in a startup or small-team environment with close collaboration across customers, product, and engineering is a plus.
• German at B2 level or above and strong English for international collaboration.
• Based in Munich or willing to relocate — on-site collaboration is required.
