• Exposure to MLOps tools: MLflow, Kubeflow Pipelines, Airflow, Argo, Vertex AI, or SageMaker.
• Strong proficiency in cloud platforms (AWS and GCP required; Azure a plus).
• Knowledge of data engineering concepts (object storage like S3/GCS, parquet/ORC, data versioning with DVC or Delta Lake).
• Experience with networking, security, and compliance (role-based access, VPC design, encryption, auditing).
• Demonstrated success in cross-functional collaboration with ML, Data, and Product teams.
• Preferred certifications: Certified Kubernetes Administrator (CKA), AWS Certified DevOps Engineer, Google Professional Cloud DevOps Engineer, NVIDIA Deep Learning Institute courses.
• AI literacy and curiosity, You have either tried Gen AI in your previous work or outside of work or are curious about Gen AI and have explored it. 
• BS Degree in Computer Science or equivalent experience.

The Roku Culture

Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the company's success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. We're independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust. In short, at Roku you'll be part of a company that's changing how the world watches TV. 

We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two-part idea. We come up with the solution, but the solution isn't real until it is built and delivered to the customer. That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
