Build the systems behind the intelligence
At RebelsAI, we turn the promise of Generative AI into products that work. We help organizations build real capabilities with AI, not just tools, but systems that scale, adapt and create impact. Our machine learning engineers design and build the technical backbone of these solutions, from data preprocessing to secure cloud deployment.
We are looking for someone who knows how to bring AI into the real world. Someone who understands the tech, sees the patterns and wants to build the next generation of intelligent infrastructure.

- Set up infrastructure using containers, APIs and serverless components
- Preprocess, chunk and structure unstructured data for optimal use in prompts and context injection
- Design, build and deploy AI-based applications in the Microsoft Azure cloud
- Configure and manage vector databases such as Pinecone or Azure AI Search
- Implement retrieval-augmented generation flows using vector databases and embedding models
- Develop orchestration logic for multi-step agents and tool-using language models
- Monitor system performance, latency, accuracy and cost
- Apply data privacy and security best practices across all layers
- Explore new GenAI frameworks and contribute to our engineering standards
- Adopt AI-tools such as Cursor and MCP's to enhance your productivity
What you bring
- You have a strong technical foundation and a curious mindset. You are eager to build real things and see them used in the world.
- A degree in AI, Data Science, Computer Science or a related field
- Strong Python skills and experience/interest in building end-to-end applications
