• Ability to work independently and take responsibility for production systems

Nice to Have

• Experience deploying ML/AI models in production
• Experience with GPU-based inference environments
• Kubernetes knowledge
• Experience with distributed systems and scaling strategies

What We Offer

• High technical ownership in a focused engineering team
• Challenging real-time AI infrastructure problems
• Flexible remote setup within European time zones
