Millions of people now use Perplexity to transform knowledge into action, and behind all of that sits the technology infrastructure that keeps a fast-moving company running. We're looking for an IT Systems Administrator who wants to do more than keep the lights on. This is an early, high-impact role where you'll build the systems and automations that let our team move even faster. You won't just respond to tickets. You'll figure out how to make them disappear. We give our IT team the same AI tools we build for everyone else, and we expect you to use them. This role is based in-person at our San Francisco office.

About Anthropic Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems. About the role Data Center Security Engineering (DCSE) secures Anthropic's data center footprint; this role covers how the sites are designed and built to be secure. Much of that footprint is designed and built with partners, so a site's security is decided early: in what Anthropic hands the people who build it, and in how rigorously the delivered systems are tested against it. You'll design and specify the physical security systems for a site: perimeter and vehicle barriers, intrusion detection, video, security lighting, and the site penetrations and utility entry points that bypass them. Design firms and integrators produce the site drawings and install; you specify, review, and verify. You'll write the performance requirement and verification method behind each control, review every site design against them at each stage with redlines a design team can act on, test in the field that what was built performs as specified, and re-verify post-acceptance changes. This is a foundational role. You'll own Anthropic's physical security reference design package (typical details, reference drawings, schedules, and test procedures) in the form partners build from, and keep it current against each site's threat basis and the sites actually being built. You'll set the technical position for a site and decide what applies where; where a requirement can't be met as written, you'll engineer the compensating control and document the deviation. You'll work with the rest of DCSE, with Anthropic's design, construction, and real estate counterparts, and directly with the vendors who build to the package. We use Claude throughout our engineering workflow

We work directly with product and engineering teams to identify risks early, influence secure architecture, and define security requirements. We build and leverage automated security capabilities to expand testing coverage, validate fixes, and reduce recurring vulnerabilities. As AI accelerates software development, our goal is to help Plaid maintain strong security without relying on manual reviews for every change. This role is perfect for you if: You enjoy understanding complex products and systems and finding security risks that are not immediately obvious. You have strong application security fundamentals and are comfortable working directly with code and architecture. You enjoy working closel

PagerDuty, Inc. (NYSE: PD) is the global leader in AI-first digital operations. By automatically detecting, diagnosing, and remediating issues, the PagerDuty Platform orchestrates AI agents and automated workflows with context from over 750 integrations. Trusted by approximately two-thirds of the Fortune 100 and nearly half of the Fortune 500, PagerDuty is the industry standard for organizations scaling resilient, autonomous operations. Notable customers include Chipotle, Cloudflare, Docusign, Fox, Nvidia, Salesforce, Spotify, Zoom and more. We are growing rapidly and hiring top talent with leading AI skills across engineering, sales, product, marketing, and beyond as we build the leading digital operations platform. Senior Security Engineer — Cloud Security (Platform Engineering, Kubernetes & Identity) PagerDuty is seeking a Senior Security Engineer to join our Cloud Security team, part of Security Engineering within the CTO organization. This is a preventive, platform-focused role for a strong engineer: you'll build and operate security-focused systems at scale to protect PagerDuty's multi-account AWS environment and the Kubernetes platforms running on it, with deep responsibility across container security and identity & access management (and, ideally, cryptography and key management). You'll harden the platform, design least-privilege identity and workload identity, and — because we're a lean team without a dedicated SOC — you'll shape detection strategy for the domains you own (Kubernetes and identity) and hunt during incidents. We lean hard into AI to move faster, so you'll both use and build agentic solutions to streamline how the team hardens, threat models, assesses risk, and operates. You'll partner with 30+ engineering teams to unblock them securely, and since we own and operate what we build, your controls ship as code, get validated against real usage, and roll out without disrupting engineering — including across our FedRAMP footprint. *
