• Build and automate secure CI/CD pipelines for deploying, updating and querying models and applications
• Implement strict security and monitoring frameworks to keep the infrastructure tightly controlled and reliable
• Act as the technical bridge between the AI development team and the core IT infrastructure department

Required profile

• 5+ years of professional experience in DevOps, cloud infrastructure or systems engineering
• Knowledge of model inference, including serving architectures, deployment strategies and scaling latency and throughput
• Understanding of hardware configurations and resource allocation for heavy workloads
• Practical security, cost-efficiency and reliability mindset
• Good communication and critical thinking skills
• Proficiency in Estonian preferred; current residency in Estonia required, as relocation assistance is not provided
