About the project

US-founded media company operating email newsletters at scale – millions of subscribers across finance, health, and business verticals. Small engineering team, flat structure, direct ownership, fast iteration. No layers of approval, no large org to navigate.

You'll own the integration and infrastructure layer alongside a counterpart engineer who handles the AI and automation side. The AI systems depend on what you build staying reliable.
 

What you'll work on

• Custom CRMs and operational tools tailored to internal workflows
• Browser automation pipelines with Playwright for interacting with and validating UI workflows
• Distributed automation infrastructure: proxy management, session handling, request routing
• PostgreSQL data models and pipelines that AI systems and operational teams depend on
• Integrations with third-party APIs and platforms – including ones with inconsistent or undocumented APIs
   

Requirements

• 6+ years of backend development
• 4+ years of production Python
• Strong PostgreSQL: schema design, indexing, query optimization – not just ORM usage
• Hands-on Playwright or equivalent (Selenium, Puppeteer) for real browser automation
• Experience with proxy infrastructure: rotation, health checking, geographic routing
   

Tech stack

Python · FastAPI · PostgreSQL · Playwright · Docker · proxy infrastructure · REST APIs and webhooks · third-party platform integrations
 

Conditions

• B2B contract, full-time
• Warsaw office (onsite preferred, remote considered)
• Direct collaboration with technical PM and small senior team
• Fast-moving environment: ambiguity, shifting priorities, growing scope

You'll own the AI layer of the automation platform alongside a counterpart engineer who handles integration and infrastructure.

• Agent systems coordinating multi-step operational tasks: content, QA, validation, reporting
• RAG pipelines over internal knowledge bases and operational data

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

Requirements

• 4+ years of production Python
• 2+ years shipping production systems with LLMs and agents
• Solid understanding of what happens underneath the frameworks: tokenization, context windows, function calling, when RAG helps and when it doesn't
