🧠 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 integration and infrastructure layer. The AI systems on the other side of the team depend on what you build staying reliable. You’ll integrate with platforms that have inconsistent or undocumented APIs, build resilient automation that handles real-world conditions, design schemas that won’t regret themselves in six months, and keep the whole stack running.

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

• 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, and request routing
• PostgreSQL data models and pipelines that AI systems and operational teams depend on
• Integrations with third-party APIs and platforms

📌 Requirements

• 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

📌 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
