Staff Server Engineer, Agent Platform

We are hiring a Staff Server Engineer to build an AI agent platform for a game studio in Prague and Bratislava. The studio is building a large cross-platform strategy game for mobile and PC with one of the biggest mobile game publishers in the world. Nearly 400 people work on the project across Europe.

This is a senior technical role with no people management. You will own a whole platform, from architecture to production. Your users are the engineers on the project. You don't need game industry experience.

What you will do

• Build an internal AI knowledge platform. It collects information from Confluence, cloud storage and other tools, stores it in a vector database and connects it to internal and external models.
  
• Build MCP connectors, agent skills and integrations, so engineers can ask the AI about features, status and code.
  
• Design and run event-driven cloud services for automation, integrations and safe AI agent execution.
  
• Set the patterns for access control, observability, audit, privacy and safe AI use.
  
• Lead unclear, high-impact projects from discovery to production.
  
• Help other teams through architecture reviews, standards and coaching.
  

Requirements

• 10+ years building and running production server-side systems in Python, Go, C# or similar.
  
• Real, hands-on work in the last 1–2 years building LLM systems: RAG or knowledge systems, vector databases, AI agents, MCP or sandboxed execution. Using AI to write code is not enough.
  
• Complex, distributed, high-availability systems.
  
• AWS, containers, Kubernetes, CI/CD, infrastructure as code and secure service-to-service communication.
  
• Ability to choose simple solutions and explain trade-offs to different audiences.
  
• Willingness to work beyond the server when needed, including Unity tools.
  

Benefits

• Full-time employment contract in Czechia or Slovakia.
  
• Hybrid work from modern offices in Prague or Bratislava.
  
• Ownership of a new AI platform used by hundreds of engineers.
  
• Company hardware and benefits.
