Customer Support Engineer

About the Role We're a fast-growing, Y Combinator-backed startup building AI-driven software that automates quoting and order processing for distributors and manufacturers. Our platform integrates deeply with enterprise ERP and CRM systems, and our customers rely on it for core daily operations — so reliability and speed of resolution matter enormously.

You'll sit at the intersection of product, engineering, and customers — debugging production issues, building AI-powered support automation, and turning recurring problems into lasting improvements. This is an on-site role in Munich , working closely in person with a small, high-calibre team. What You'll Do Investigate and reproduce production issues across product, data, integrations, and workflows. Dive into logs, databases, customer examples, and the codebase to identify root causes. Own technical resolution end-to-end — and fix issues directly where possible. Communicate clearly with customers to understand problems and ensure they feel well supported. Design and deploy AI agents that automate customer interactions and accelerate resolution times. Operate and manage AI agent workflows that assist investigation and escalate to core engineering when 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 changes. Work closely with engineering and product leadership to shape the support function as the company scales. What We're Looking For Must-haves: At least 1 year of full-stack software engineering experience delivering production-grade code across React, TypeScript, Python, and PostgreSQL . Demonstrated ability to ship production code and debug real-world software issues across logs, databases, APIs, and unfamiliar codebases. Proven ability to own technical customer resolution end-to-e
