Customer Support Engineer

ABOUT THE ROLE
This is a Customer Support Engineer role at a Y Combinator-backed AI sales automation startup, sitting at the intersection of product, engineering, and customers. You will own technical issue resolution end-to-end, from root-cause debugging to shipping fixes, while also building AI agents that automate and accelerate support workflows. The role has a direct impact on the reliability of a platform that customers depend on for core business operations.
WHAT YOU'LL DO
- Investigate and reproduce production issues across product, data, integrations, and workflows.
- Dig into logs, databases, customer examples, and the codebase to identify root causes.
- Own technical resolution end-to-end and fix issues directly when 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 workflows, flagging when core engineering input is required.
- 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 engineering and product teams as the company scales.
WHAT WE'RE LOOKING FOR
- At least 1 year of full-stack software engineering experience delivering production code.
- Hands-on proficiency with React, TypeScript, Python, and PostgreSQL.
- Proven ability to debug independently across logs, databases, APIs, and unfamiliar codebases.
- Comfortable with customer-facing work and able to use user conversations to prioritize fixes.
- Structured, reliable, and people-oriented approach to support and ownership.
- German proficiency at B2 level or above, with strong English for international collaboration.
- Experience designing or deploying AI agents for support automation is a plus.
