Job Description

Remote

This team will provide 24x7 white-glove support to people using large blocks of GPUs (6,000+ contiguous GPUs) for a short period of time (eg: 6-weeks, 12-weeks etc) to perform Managed Post Training (MPT). This includes helping with preparation, 24x7 support during training to ensure full utilization of the GPU clusters and off-boarding. The team is in three timezones with hand-off protocols to enable 24x7 support: US, Europe and India. While you can be a specialist in Infra and cluster operations, you need to know enough about ML.

Job responsibilities

  • You will help shape and iterate this new white glove model training support service on large GPU clusters.
  • You will work in a collaborative team with Machine Learning Engineers and Infrastructure Engineers.
  • You will contribute to accelerator development: find gaps in the tooling, or needed automation, or patterns we would develop accelerators to make the next round of this more efficient and faster. Eg: We need to improve observability, or we need to automate user onboarding, or we need to bring in a new tool which everyone seems to want to use etc. This will probably involve a combination of Terraform/Pulumi, Helm Charts, Python and Shell Scripts.
  • You will help assess the model training readiness and data preparation.
  • You will provide model training support rotating daytime weekend shifts - with pagers, to any issues they may encounter. These can range from infrastructure issues to data sciences issues or anything in between: eg: GCP changed a configuration in GKE that affects the training.
  • You will facilitate collaborative problem solving within the team by actively listening, communicating effectively and mentoring other engineers.
  • You will proactively identify and address challenges related to the white glove service for continued pre training, proposing solutions and implementing improvements.
