We look forward to receiving your application (CV, GitHub/portfolio, salary expectations, earliest possible start date).
Prompt Engineer / AI Operations (m/w/d) • Hamburg • hybrid
We are not looking for a pure “copywriter,” but an AI Operations Manager who understands the logic behind the models and can bridge the gap to development.
Since the market for experts is highly competitive, we follow a high-potential model: we are looking for someone with strong technical affinity and excellent language skills, whom we will train internally on our tools (e.g., LangFuse).
Through your work, you will relieve the developers, allowing them to focus on core architecture and new features. At the same time, you will help improve product quality by making AI outputs more consistent and precise, control costs through optimized prompts and API usage, and build internal know-how across various AI models to ensure the long-term security of our platform.
Prompt Strategy & Management
- Structure, manage, and version hundreds of internal prompts for PAIDAI.
LLMOps with LangFuse
- Actively operate LangFuse for tracing, monitoring, and performance evaluation of AI responses.
Quality Assurance
- Conduct systematic A/B tests of different prompt versions and models (OpenAI, Anthropic, etc.).
Technical Bug-Fixing
- Identify and fix errors in outputs (e.g., formatting issues, hallucinations) directly at the interface to the code.
Efficiency Improvement
- Optimize token usage (cost control) and response speed through efficient prompt design.
-
Background in (Computational) Linguistics, Business or Media Informatics, or a comparable degree with a focus on structure and language.
-
Basic technical understanding (e.g., APIs, JSON formats).
-
Confident handling of variables and logical chains.
-
Excellent German and English skills.
-
Analytical mindset, strong experimentation drive (“trial and error”), and a structured way of working (data over gut feeling).
-
High Impact: Work on a cutting-edge AI product and directly contribute to quality and user satisfaction.
Autonomy: Work independently with plenty of decision-making freedom and direct influence on prompt strategy and internal processes.
Career: Opportunities to develop into Senior Prompt Engineer, AI Operations Lead, or similar roles.
Flexibility: Hybrid working (Hamburg office in the city center) or remote.
Team Spirit: Collaborate in an interdisciplinary, motivated team from Product, Engineering, UX/UI, Business, and Legal.
We look forward to receiving your application (CV, GitHub/portfolio, salary expectations, earliest possible start date).
