Founding Engineer - AI Infra (Hybrid, Lviv)

Required Qualifications

• 5+ years of backend / platform engineering experience
• You've shipped something end to end. A side project, indie product, or work project where you personally took it from idea to production and real users: architecture, code, deployment, and operations
• Daily user of agentic coding tools (Claude Code, Codex, Cursor, or similar), you build with them, understand how they call models and tools under the hood, and can reason about routing, configuration, and extending them
• Comfortable building and owning everything alone, you don't need a team around you to be effective. You can take a problem from design through implementation, deployment, and operations solo, and stay productive without structure, standups, or someone else unblocking you
• Comfortable with deep product ambiguity: there is no incumbent to copy in this category. We'll be designing the product and the architecture from first principles, choosing the stack, making design calls no one has made before, shipping fast, and owning outcomes end to end

• Strong cloud computing experience (AWS, GCP, or Azure): networking, load balancing, container orchestration, and running production workloads - you've operated real systems, not just deployed demos
