Workload Porting And Performance Engineer Jobs

About the Team OpenAI's data and storage infrastructure spans data platforms, online databases, and file/object storage. These systems underpin data ingestion and processing, durable persistence, indexing and retrieval, and product file experiences. As frontier models and agents evolve how they use memory, history and snapshots, the underlying architecture increasingly shapes the capabilities products can deliver—and their latency, reliability, cost and efficiency. About the Role We are looking for a technically deep TPM to independently define and lead multiple programs across data platforms, online databases and storage infrastructure. You will connect model, product and data-consumer requirements to architecture, and work with the relevant engineering teams to take new capabilities through production adoption and repeatable expansion. The design scope is exabyte-scale storage and infrastructure spanning multiple millions of CPU cores. The challenge is not simply forecasting more resources: it is making complete, workload-ready capacity repeatable, with a clear path from product requirements through architecture, deployment and validation. A data pipeline, database query, file operation or execution snapshot can affect whether a product or agent succeeds; you will connect those outcomes to the systems underneath. This role is based in San Francisco, CA. We use a hybrid work model of 3 days in the office per week and offer relocation assistance to new employees. In this role, you will: Translate model, product and data-platform needs into precise access patterns, consistency, durability, freshness, availability and scalability requirements. Connect memory, history, retrieval and resumable work to capability and end-to-end latency. Partner with engineering to transform data and storage architecture into repeatable scale units: standardized provisioning, placement, routing, data movement and readiness checks that bring storage, compute and networking online together.

About the Team The Industrial Security team enables OpenAI’s classified and national security work by building secure, compliant programs that support government customers and protect sensitive information. Within Industrial Security, the Personnel Security function ensures employees have the clearances, accesses, briefings, and government approvals required to support classified programs. We work closely with employees, program teams, government customers, and partners across Security, People, Recruiting, Legal, IT, and Facilities to make complex security processes accurate, timely, and understandable. About the Role As a Personnel Security Specialist, you will own the day-to-day personnel security operations that allow OpenAI employees to support classified government work. You will manage clearance and access requests, maintain government-system records, coordinate visits and briefings, support onboarding and offboarding, and guide employees through sensitive security requirements with discretion and care. We’re looking for a hands-on security professional who can independently manage a high-volume operational queue, keep cases and records organized, recognize when issues require escalation, and improve the processes behind the work. This role offers the opportunity to help build a modern personnel security function that supports important national security programs while delivering a thoughtful, responsive employee experience. This role is based in San Francisco, CA, or Washington, DC. We use a hybrid work model of three days in the office per week and offer relocation assistance to new employees. Additional onsite presence and occasional travel may be required based on classified program and government customer needs. In this role, you will: Own the daily personnel security workload from intake through completion, including clearance verification, access nominations, visit requests, onboarding, offboarding, briefings, and reporting actions.
