Security Reliability Engineer
OpenAIAbout the Team
The Infrastructure Engineering function sits within IT and is responsible for reliably building, deploying, and operating critical on prem and hybrid environments that power internal services and critical R&D environments.
This is a new, bootstrap team focused on applying strong Site Reliability Engineering discipline to environments where uptime, safety, recoverability, and security are non-negotiable. The team replaces bespoke, one off infrastructure with standardized infrastructure-as-code building blocks that compound reliability and operational leverage as OpenAI scales.
About the Role
We are looking for a Security Reliability Engineer to design, build, and operate reliable, secure, and scalable infrastructure that underpins identity, access, endpoint, and shared platform services across the company.
In this role, you will own infrastructure and identity systems end to end, from foundational design and provisioning through policy enforcement, upgrades, recovery, and day two operations. You will establish durable, production grade platforms that remove operational friction, enforce security by default, and enable teams to move faster with confidence.
This role is well suited for a senior engineer who thrives in ambiguity, enjoys owning complex systems end to end, and raises the reliability and security bar by replacing fragile implementations with standardized, repeatable infrastructure.
This role is based in our San Francisco HQ and requires in-office presence.
In this role, you will:
Set direction and establish strong foundations
Define and evolve infrastructure patterns for on prem and hybrid environments, including self hosted platforms, vendor supported systems, and lab environments.
Establish standardized, production grade deployment and operational models that replace bespoke implementations.
Partner with IT, Security, Identity, and Network teams to ensure infrastructure meets reliability, security, and access requirements by design.
Design and mature the production architecture for IAM adjacent platforms such as Microsoft Entra using SRE principles.
Establish common management rules and shared resources within Azure subscriptions to ensure consistent, policy aligned operations.
