REALM; United States; Remote; USD 180,000 - 240,000; Full time

Job summary

REALM is seeking a senior, hands-on storage architect to own the Ceph-based infrastructure powering petabyte-scale storage for GPU-intensive workloads. You will oversee architecture, deployment, and day-to-day operation across object, block, and file services.

You will mentor engineers, drive technical direction, and collaborate with compute/network teams, while participating in a shared on-call rotation with compensation.

Qualifications

• Strong practical experience with Ceph covering architecture, deployment, troubleshooting, day-to-day operations, and optimisation.
• Experience running distributed storage infrastructure at significant production scale.
• A history of taking ownership of an infrastructure or storage domain and driving its technical direction.
• Experience supporting and developing other engineers through mentoring and technical collaboration

Responsibilities

• Own the architecture and production lifecycle of Ceph-based storage infrastructure at very large scale.
• Help develop and operate an S3-compatible object storage offering, including access control, bucket and object workflows, reliability targets, observability and incident response
• Work across the Ceph stack, including RADOS Gateway, RBD, and CephFS
• Provide technical mentorship through design discussions, reviews, pairing, and participation in the on-call rotation
• Evolve the storage platform as capacity grows from the petabyte range into substantially larger deployments
• Partner with infrastructure teams responsible for compute and networking to ensure storage meets the needs of high-performance and GPU-heavy environments

Job description

A fast-growing Neocloud - running the GPU infrastructure behind the next wave of AI companies, with storage as the foundation the whole platform sits on.

Strong revenue, well-funded, and growing fast - profitable and customer-backed well before the GPU buildout began.

The Role

This is a senior, hands-on role with broad technical ownership. You’ll take responsibility for the architecture, deployment, and day-to-day operation of large Ceph environments storing customer data at petabyte scale across object, block, and file services. The infrastructure supports demanding GPU and compute workloads, and you’ll play a key role in defining the direction of the storage platform and making the major technical decisions around it.

Specifically:

• Own the architecture and production lifecycle of Ceph-based storage infrastructure at very large scale
• Help develop and operate an S3-compatible object storage offering, including access control, bucket and object workflows, reliability targets, observability and incident response
• Work across the Ceph stack, including RADOS Gateway, RBD, and CephFS
• Provide technical mentorship through design discussions, reviews, pairing, and participation in the on-call rotation
• Evolve the storage platform as capacity grows from the petabyte range into substantially larger deployments
• Partner with infrastructure teams responsible for compute and networking to ensure storage meets the needs of high-performance and GPU-heavy environments

Who they’re looking for

• Strong practical experience with Ceph covering architecture, deployment, troubleshooting, day-to-day operations, and optimisation
• Experience running distributed storage infrastructure at significant production scale
• A history of taking ownership of an infrastructure or storage domain and driving its technical direction
• Experience supporting and developing other engineers through mentoring and technical collaboration
• Solid Linux and networking fundamentals, with the ability to investigate complex issues across distributed systems
• Willingness to participate in a shared production support/on-call rotation
• The storage function is expanding, with a combination of experienced and developing engineers
• The role is remote
• Production support is shared across the team through a regular on-call schedule, with additional compensation for on-call participation
