- Implement monitoring, logging, and alerting for model performance and system health
- Optimize infrastructure costs while maintaining performance and availability
- Automate deployment workflows using infrastructure-as-code and CI/CD practices
- Collaborate with ML engineers and researchers to move models from experimentation into production
- Proactively identify bottlenecks, investigate root causes, and resolve infrastructure issues

Required Qualifications:
- Proven experience building large language model infrastructure (non-negotiable)
- Hands-on experience deploying and serving machine learning models in production environments
- Strong programming skills in Python, with experience in systems or backend development
- Experience with containerization and orchestration tools such as Docker and Kubernetes
