• Exposure to Terraform or another IaC system, along with DevOps and GitOps.
• Knowledge of CI/CD best practices and building CI/CD pipelines.

Nice to have

• Domain experience in advanced materials, drug discovery, cheminformatics, or other areas of chemistry or biology, especially experience with AI systems applied to these domains.
• Delivering scientific code for R&D projects, especially in the simulation and numerical optimization domains
• HCP systems, GPU programming and optimization
