Founding Engineer

About the Role This is a founding engineering position at a YC-backed enterprise AI startup building agents that automate complex system integrations, migrations, and implementations — the kind of critical infrastructure work that typically takes consultants months to deliver. You'll join a small, senior team and have direct influence over the architecture, culture, and engineering bar for everyone who comes after you. What You'll Do Build the agent core: the planning, execution, and self-healing loops that turn natural-language integration descriptions into production-grade data movement. Own systems end to end — connectors, transformation engine, execution runtime, web app, SDK, and MCP server — picking up the highest-leverage problem each week and shipping it. Work on production-critical infrastructure that operates directly on live ERP and financial systems, where reliability and failure-mode awareness genuinely matter. Join customer calls when technical depth is needed, translating real-world requirements into product decisions. Set the engineering patterns and standards that the next wave of engineers will build on. What We're Looking For 2+ years of software engineering experience building and operating production systems. Strong proficiency in TypeScript with demonstrated experience building full-stack, end-to-end applications. Experience designing and implementing critical infrastructure with sound judgment on reliability and scalability. Hands-on experience integrating with or implementing enterprise systems such as ERPs, CRMs, or data warehouse platforms (e.g. SAP, NetSuite, Salesforce, Snowflake, or similar). Proficiency in at least one additional language beyond TypeScript — Python, Go, or C. Experience working directly with customers on technical implementations or support. Experience building or meaningfully contributing to open source projects. Background in data migration, ETL, or system integration work is a strong plus. Strong CS fundamentals from a rigorous academic background or equivalent demonstrated depth through competitive programming or impactful internships. Comfortable in an early-stage environment with limited process and high ownership. Clear, direct communicator — with teammates and with customers alike. Compensation & Benefits Salary range: €90,000 – €150,000 annually. Visa sponsorship is not available. Location On-site in Munich, Germany .
