Staff Security Reliability Engineer

About 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 an early high-leverage technical role focused on applying strong Site Reliability Engineering discipline to environments where uptime safety recoverability and security are non-negotiable. This person helps replace 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 an experienced Site Reliability Engineer working on security infrastructure 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 be a senior technical owner for infrastructure and identity systems end to end from architecture and implementation through policy enforcement upgrades recovery and day-two operations. You will build 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 hands-on 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:

• Design build and operate reliable infrastructure across on-prem hybrid shared and product adjacent environments.

• Establish standardized infrastructure patterns that replace bespoke implementations with repeatable auditable secure-by-default systems.

• Own the lifecycle of critical infrastructure platforms including provisioning deployment upgrades patching recovery and long-term reliability.

• Build infrastructure-as-code and configuration management using tools such as Terraform Chef and Ansible.

• Mature identity adjacent and policy enforced infrastructure including Microsoft Entra and Azure management patterns.

• Build observability alerting and incident response mechanisms that improve availability recoverability and operational confidence.

• Automate high-toil and high-risk workflows with guardrails progressive rollout patterns and safe rollback paths.

• Translate incidents design reviews and operational learnings into durable fixes reusable patterns and stronger technical standards.

• Influence cross-functional partners across security identity network and platform teams through architecture implementation operational data and clear technical writing

You might thrive in this role if you:

• Have 10 years of hands-on experience operating and architecting mission-critical infrastructure in high-reliability environments

• Have experience running Security Infrastructure

• Have been the senior technical owner for the design and maturation of complex on-prem hybrid or cloud-integrated systems setting durable architectural patterns used by multiple teams

• Apply Site Reliability Engineering principles at scale using observability automation and incident learnings to materially reduce risk and operational toil

• Operate comfortably in ambiguity making sound architectural decisions under pressure while staying close to technical detail

• Have experience operating infrastructure for R&D or specialized labs manufacturing or other safety critical environments where uptime and recoverability are essential

• Have experience with fleet endpoint or virtual desktop platforms such as FleetDM Chef or Azure Virtual Desktop

• Have experience partnering closely with identity or security engineering teams on hardened policy enforced infrastructure at scale
