Reflow is seeking an AI Engineer for an onsite role in Berlin to help build Reflow AI, an agentic automation platform. You will develop and optimize AI pipelines, experiment with prompt engineering, context tuning, and model orchestration, work with vector databases and RAG, and collaborate with product teams to embed AI into workflows. Ideal candidates have 2+ years in agentic AI with external users and 4+ years in backend engineering, strong Python and LLM skills, and a track record turning uncertainty into working systems. Bonus for LangChain or OpenAI API, desktop or web app integration, automation domains. To apply, tailor your resume to show outcomes, include prototype links, and highlight collaboration with founders and engineers.

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.
