- Drive continuous improvement in infrastructure automation, deployment, and orchestration using tools like Kubernetes, Flux, Terraform

- Collaborate with AI/ML researchers to develop and implement solutions that enable safe and reproducible model-training experiments

- Build a cloud-agnostic platform offering an abstraction layer between science and infrastructure

- Design and develop new workflows and tooling to improve to the reliability, availability and performance of our systems (automation scripts, refactoring, new API-based features, web apps, dashboards, etc.)

- Collaborate with the security team to ensure infrastructure adheres to best security practices and compliance requirements

- Document processes and procedures to ensure consistency and knowledge sharing across the team

- Contribute to open-source projects, research publications, blog articles and conferences
