You will work alongside talented engineers in the Data & Digital Catalyst organisation to design resilient, cloud-based systems for MLOps and HPC workloads at global scale. This is a role for someone who wants their engineering craft to have real impact on science and patients.

The Opportunity:

• You architect Infrastructure as Code using Terraform, Pulumi, or CloudFormation to provision and manage cloud infrastructure for MLOps and HPC workloads across global regions.
• You design for resilience building disaster recovery and failover plans with auto-scaling and load balancing to keep critical systems available worldwide.
• You strengthen reliability through chaos engineering running experiments that validate systems and surface weaknesses before they become incidents.
• You build deep observability with monitoring, logging, and alerting frameworks such as Prometheus, Grafana, Datadog, and ELK.
• You provide technical leadership to a team of engineers, fostering collaboration, innovation, and continuous improvement.
• You partner across teams to align infrastructure with ML and HPC needs and to advance operational maturity through SLAs, SLOs, SLIs, and error budgets.

Who you are:

• You bring deep expertise in Infrastructure as Code with proven success deploying Terraform, Pulumi, or CloudFormation in AWS, Azure, or GCP for MLOps and HPC workloads.
• You understand cloud-native and on-prem architectures including autoscaling, serverless, and multi-region deployments, and you are hands‑on with Docker, Kubernetes, and Kubeflow.
• You are an expert in automation scripting confidently in Python, Bash, or Go, with a strong grasp of GPU‑accelerated computing and HPC workload scaling.
• You lead through influence communicating and mentoring with clarity, and solving complex problems with a methodical approach.
• You hold a degree in Computer Science or a related technical field or bring equivalent experience in software and site reliability engineering.

Preferred:

• Experience with distributed ML frameworks such as Horovod or TensorFlow Distributed.
• Familiarity with data engineering pipelines such as Apache Airflow or Apache Spark.
