We are an independent German digital marketing agency with proprietary technology. hurra.ai is our AI product, a growing platform that sits at the intersection of marketing intelligence and artificial intelligence. We are expanding the small, focused team building it.
We are looking for an experienced freelance full-stack Django developer to join us on a part-time basis and contribute to the continued development of hurra.ai.

Tasks

• Integrate third-party APIs and AI services, including LLM providers such as OpenAI, Anthropic and OpenRouter, as well as marketing data sources.
• Write clean, maintainable Python code and contribute to a well-structured, evolving codebase.
• Work independently in a remote environment, manage your own workload, and communicate clearly with a small, senior team.
