AI-Native Senior Software Engineer (Customer-Facing)

Role overview A Europe-based AI company is looking for a senior, customer-facing software engineer to sit between clients and the platform, translating ambiguous business needs into reliable production systems. The work centers on building and maintaining automated evaluation and testing infrastructure that lets customers ship AI agents safely in high-stakes environments.

Responsibilities - Take loosely defined business problems from customers and turn them into working systems that stay working - Own customer-facing builds from zero through production, including follow-through to completion - Pick up subtle signals in conversations, infer what stakeholders actually need, and deliver against those needs - Pressure-test requirements, pushing for clarity where the right behavior or supporting data is unclear - Write down why each feature matters to the customer, whether in a presentation, a commit message, or a PR description - Act as the person colleagues and customers plan around, carrying work to a high-quality finish

Requirements - Several years of experience building and operating production software such as APIs, backend services, or data pipelines - A track record of owning a customer-facing build from zero to production, ideally more than once - Hands-on experience with large language models and agent frameworks in real production systems, not just prototypes - Strong engineering discipline around automated testing, CI/CD, and monitoring - Demonstrated time in a customer-facing role, such as consulting, forward-deployed engineering, founding a company, or an in-house role embedded with the business - Working proficiency in English

Nice to have - Professional working proficiency in German, since a meaningful share of the data and many customers are German-speaking - Familiarity with TypeScript and Python, along with cloud infrastructure tooling - Experience with AI-assisted development workflows such as Claude Code

Benefits and work setup - Full-time, fully remote role hiring across Europe - Approximately 10% travel expected for customer engagement and team activities
