Reflow is seeking an AI Engineer to build agentic AI pipelines for its workspace intelligence platform. This full-time onsite role in Berlin focuses on prompt engineering, context tuning, model orchestration, vector databases, and retrieval-augmented generation to improve real-world workflows. You’ll work with engineers and product teams to ship production systems and continuously refine models through experimentation and data feedback. Ideal candidates have 2+ years deploying agentic AI to external users, 4+ years backend experience, strong Python and LLM foundations, and hands-on AI pipeline design. Bonus for LangChain, OpenAI API, and desktop or web app integration. To apply, tailor your resume to show scalable AI work with metrics, prototypes in production, and links to demos or code.

We’re building Reflow, a workforce and workflow intelligence platform that helps teams understand and improve how work gets done. A key part of that vision is Reflow AI, agentic, automation-focused intelligence that adapts to how people actually work. We’re looking for an AI developer who can experiment fast, optimize intelligently, and help us push the boundaries of AI-assisted performance.

What you’ll do

  • Develop, optimize, and maintain agentic AI pipelines for automation and workflow intelligence.

  • Experiment with prompt engineering, context tuning, and model orchestration to improve performance and adaptability.

  • Work with vector databases, RAG (retrieval-augmented generation), and related frameworks for contextual intelligence.

  • Collaborate with engineers and product teams to integrate AI systems into real-world workflows.

  • Continuously refine and improve models through experimentation, data feedback, and iterative development.

Who you are

  • 2+ years working on agentic AI systems that have scaled to external users

  • 4+ years as a Backend Developer or similar engineering role

  • Strong foundation in Python, LLMs, and agentic architectures.

  • Experienced in prompt engineering, context optimization, and AI pipeline design.

  • Comfortable building fast prototypes and testing model behavior in varied, complex contexts.

  • Curious, pragmatic, and unafraid to experiment, you turn uncertainty into working systems.

Bonus points

  • Experience integrating AI into desktop or web apps.

  • Familiarity with LangChain, OpenAI API, or similar frameworks.

  • Background in automation systems, workflow optimization, or enterprise AI tools.

Why join

You’ll help shape the intelligence core of Reflow, the layer that learns from work patterns and turns data into action. You’ll work across experiments, prototypes, and production systems, collaborating directly with founders and engineers. Ideal for someone who loves to push AI beyond the theoretical into the real.
