🧠 About Us
At EPC Network, we’re not just a digital marketing company; we’re a platform for career transformation and personal growth. Our people-first approach shapes our corporate culture, fostering a team of passionate, smart, and energetic individuals who strive to grow professionally in an international, fast-paced environment.

We believe our Team is the foundation of our success, and now we’re looking for an AI Automation Specialist to join our Automation & Technical Operations direction!

🎯 Job Description
As an Senior Python Engineer, you’ll design, build, and maintain intelligent automation systems that remove manual work, reduce errors, and dramatically increase execution speed across the company.

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.

You’ll collaborate closely with Marketing, Publishing, Analytics, and Technical Operations teams to turn complex, manual processes into clean, scalable, and reliable automated workflows.

🔧 Key Responsibilities

• 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

📌 Requirements

• 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

📌 Nice to Have

• Experience with email or newsletter platforms (Substack, Ghost, Beehiiv, or similar)
• Understanding of UTMs, tracking links, SubIDs, and attribution logic
• Experience automating QA around links, formatting, and tracking
• Background in media, publishing, or high-volume content operations

Our tech stack: Python, FastAPI, PostgreSQL, LLM APIs (OpenAI, Anthropic), LangChain/LangGraph/MCP, vector databases, Playwright, Docker, proxy infrastructure

🤝 What it means to be part of our Team

🎓Your professional and personal development:

• Multinational and intercultural experience
• Corporate library
• A world-class team to work with
• Growth opportunities
• Cutting-edge frameworks and technologies

🧘Well-being:

• Competitive salary
• Plenty of engaging team-building and social events
• Bonuses according to the policy
• 21 paid vacation days & 14 paid sick leaves;

😌Working environment:
