Senior Python Engineer. AI and Automation

Location: Warsaw, Poland (hybrid, office or remote)

Contract: B2B, full-time 

Seniority: Senior

Media Miami is an independent performance marketing agency focused on building and scaling digital products.

Our core expertise lies in developing and growing media ecosystems for global audiences, with a strong focus on the U.S. market. We operate across key verticals, including finance, health, self-development, and astrology — delivering relevant insights, practical value, and highly engaging experiences.

The team

Small engineering team alongside a technical PM. Flat structure, direct ownership, fast iteration. You'll have a counterpart engineer owning the integration and infrastructure layer.

What you'll build

• AI-driven content generation and management workflows at production scale
• Agent systems coordinating multi-step operational tasks: content, QA, validation, reporting
• RAG pipelines over internal knowledge bases and operational data
• Prompt architectures designed for reliability, cost control, and measurable output quality

• Evaluation and regression testing for LLM systems "it looked fine when I tested it" isn't enough

   

The work

You own the AI layer of our automation platform. Real production systems, not demos. The work removes hours of manual operational work daily, and it needs to be reliable enough that people actually trust it.

Expect ambiguity, shifting priorities, and scope that grows fast. You'll ship working code, learn what breaks in production, and iterate quickly.

What we need

• 6+ years dev experience
• 4+ years of production Python
• 2+ years shipping production systems with LLMs and agents
• Solid grasp of what happens underneath the frameworks: tokenization, context windows, function calling, when RAG helps and when it doesn't
• Hands-on with agent orchestration (LangChain, LangGraph, MCP, or equivalent)

• Clean, maintainable Python without relying on frameworks to do your thinking
