LichtBlick is looking for you. Starting immediately. Part-time or full-time and permanent. For good energy in the field of technology.
Role purpose
You design and develop agentic AI applications based on LLMs - from the initial idea through prompt design and agent architecture to the productive solution. At the same time, you ensure that these solutions run on a solid technical foundation - from data integration and model access to deployment, monitoring, and continuous improvement.
What you'll do
- You design and implement agentic AI applications with Microsoft Foundry and integrate them into an existing landscape of backend and frontend services
- You build RAG pipelines and data integrations so AI systems can access relevant knowledge and context
- You are responsible for testing, evaluation, and monitoring of AI applications - from response quality and latency to cost and usage patterns
- You make AI applications ready for production by applying responsible AI principles such as input/output filtering, PII protection, and red teaming
- For suitable use cases, you experiment with and use no-code/low-code platforms such as Microsoft Copilot Studio
- You work cross-functionally with business stakeholders, product teams, and engineering colleagues, and actively contribute new developments in the GenAI space.

Our application process & your contact
Our application process is designed to be transparent and open for you. We carefully review your application documents and provide you with feedback as quickly as possible. In an initial informal exchange, you will get to know your contact persons (recruitment and department) remotely. We will show you our corporate culture in action, what makes LichtBlick special, and what mindset we live by. We will be happy to answer your questions together.
Your second interview will take place in person at our office. Here you can get to know our working environment and talk to your future colleagues, because it is also important to us that we "click" on a personal level.
Is everyone in agreement? Then we look forward to shaping a sustainable and conscious future with you.
