This fully remote, part-time engagement offers flexibility and autonomy, with approximately 60 hours of work per month. It is an opportunity to contribute directly to a live AI product with an ambitious roadmap and room for new ideas.

Accountabilities:

• Build, maintain, and extend full-stack features for an AI-powered product, primarily using Django and Python.

• Develop lightweight frontend interfaces using HTMX, Alpine.js, and Tailwind CSS.

• Integrate third-party APIs, AI services, and large language model providers, including OpenAI, Anthropic, and OpenRouter.

• Connect marketing data sources and incorporate relevant data into product functionality.

• Write clean, reliable, maintainable Python code and contribute to a well-structured, evolving codebase.

• Apply modern AI-assisted development tools and workflows to accelerate implementation while maintaining strong engineering standards.

• Manage your workload independently, communicate progress clearly, and collaborate effectively with a remote team.

• Contribute technical insights, suggest improvements, and help shape product development decisions.

• Support the continued evolution of the platform by delivering features aligned with its roadmap and user needs.

Requirements:

• At least five years of hands-on full-stack development experience, preferably with Django as your primary framework.

• Strong Python programming skills and a proven track record of building and shipping production-ready products.

• Experience developing AI-powered applications using technologies such as LangChain, LangSmith, OpenAI APIs, OpenRouter, or Anthropic APIs.

• Familiarity with Docker and confident use of Git for version control and collaborative development.

• A balanced approach to software development that combines sound engineering fundamentals with modern AI-assisted workflows.

• Practical experience or familiarity with AI development tools such as Cursor, Codex, and Claude Code, with the ability to explain how you use them in your daily work.

• Experience with Google Cloud Platform (GCP), Azure, CI/CD, or DevOps pipelines is a plus.

• Frontend development skills and a strong eye for UI design and user experience are advantageous.

• German language skills are a plus, particularly for candidates who also communicate fluently in English.

• Application requirement: You must submit both your CV and a two-minute introductory video. The video should explain who you are, why you are interested in the role, and how you use AI tools in your day-to-day work. It can be recorded using Loom, a phone, or another tool; professional production quality is not expected.
