About the Team The compute infrastructure team runs the GPU fleet and large-scale compute clusters that serve the models backing ChatGPT and the API, while also supporting training workloads for our next generation models. We operate a large, modern GPU fleet and provide a unified platform for other OpenAI teams to seamlessly run production Applied AI and Research training workloads. We seek to learn from deployment and distribute the benefits of AI, while ensuring that this powerful tool is used responsibly and safely. Safety is more important to us than unfettered growth. About the Role You’ll own the hands-on and automation work that brings WAN, fiber, carrier, and cloud-interconnect circuits into service. Partner with network engineers, fiber providers, cloud service providers, colocation teams, and data-center technicians to move each connection from ordered and patched to verified, stable, and ready for handoff. You’ll own Layer 1 troubleshooting and circuit bring-up while building workflows that translate reliable system or model output into precise, approved technician actions, capture field feedback, and drive each connection to a green-port handoff. The right person combines strong physical-networking judgment with practical automation skills: patch-panel and port mappings, optics and light levels, provider coordination, structured operational data, API or scripting workflows, and human-in-the-loop LLM tooling. Responsibilities Own Layer 1 activation and restoration for carrier circuits, dark fiber, wavelengths, Ethernet handoffs, and dedicated cloud interconnects across data centers and points of presence. Reconcile complete A-side/Z-side as-builts: circuit IDs, LOAs/CFAs, carrier demarcations, MMR/ODF/MDF and patch-panel positions, fiber pairs, cross-connects, optics, and device ports. Investigate no-light, low-light, wrong-port, link-flap, and error-rate issues across providers and CSPs; isolate continuity, dirty connectors, polarity, incorrect patching

The Opportunity We are looking for an ambitious frontend engineer to own bigger and bigger portions of our UX, as part of an 0-1 initiative. With Postman Insights , our vision is to help guide a developer with little previous experience—in both the system being monitored and the Postman API Platform—to productively find and fix issues. Our goal is to be able to help any developer locate API endpoints causing potential issues within 15 minutes of signing up for an account. This will empower even a new developer to find and fix issues in their first days on the job, as easily as they can call an API today. As we prepare to launch our open beta, we’re looking for a frontend software engineer to help us bring our Postman Insights product to life. Right now, we’ve launched an alpha to a small number of users and have learned a lot from that launch. To deliver our intended developer experience, we’ll need to iterate with our users to get the UX right. We’re looking for an engineer who can focus on the frontend, excited about designing and refining the user interface on a weekly basis to get our product ready for a larger number of users.

We're building one place where your knowledge, projects, meetings, and AI tools live side by side, so work is faster, clearer, and less fragmented. Millions of individuals, small teams, and large companies run their work on Notion. Notinos (our employees) are customer zero in bringing this future of work to life. We care about craft, building things that last, and the belief that great work is still fundamentally human. Our goal isn’t to ship the next feature. Each and every team of Notinos is working to set the standard for how humans work together in the AI era. From building a business’s system of record to making and managing AI agents to automating away the busy work, we care deeply about giving our customers more time for their life’s work. About the Role: We’re seeking an experienced UX Researcher to define and scale how we evaluate Notion’s AI-powered experiences—focusing on what “good” looks like not only for model output quality, but for the end-to-end product experience where people discover, set goals, delegate work, review results, and build trust over time with AI. This role sits at the intersection of research craft and evaluation operations: you’ll run studies that uncover user mental models, expectations, and failure/recovery behaviors, then translate those insights into reusable rubrics, workflows, and measurement approaches that product, design, engineering, and data science can apply consistently. This role can be based in either San Francisco or New York City. We work from our offices on Mondays, Tuesdays and Thursdays (our Anchor Days) because we do our best thinking and building together in person. We’re looking for someone who’s excited to work alongside the team during those days. What You'll Achieve: Define what “good” looks like (frameworks & rubrics): Establish clear, reusable evaluation criteria that reflect real user expectations—helpfulness,

About the Role: Own how our Foundations business teams design, automate, and operate their most important workflows. Notion is growing quickly, and the processes that run our business — intake, triage, execution, approvals, escalations, reporting — need to scale without adding headcount or losing auditability. This role exists to redesign those processes end to end and to embed AI directly into them, so the work moves faster and the system stays trustworthy. What's different at Notion: you'll build on Notion as customer zero. You'll design multi-system workflows spanning Notion, Slack, email, support tooling, and internal data, then ship the custom agents, skills, and automations that run them — partnering with Finance, Legal, People, Ops, Data, and Engineering to drive real adoption, not just documentation.

About Sentry Software runs the world and the pace is faster than ever. Sentry helps developers fix errors and performance issues before users notice, so teams can spend less time firefighting and more time building. Trusted by 200,000+ organizations, Sentry is today’s application monitoring standard and our team is building its AI-native future. About the Role Shipping great software is only half the battle. Getting it to the right customers, at the right time, in the right way, is where the real complexity lives. We're looking for a Senior Technical Program Manager to own the end of the EPD pipeline: the moment a feature is built to the moment it's successfully in customers' hands. This person will define what "good" looks like for product launches at Sentry, building the frameworks, playbooks, and operating rhythms that make every release more intentional, more coordinated, and more confident than the last. The foundation is there. Features ship. But the connective tissue between Engineering, Product, Legal, Marketing, go-to-market (GTM), and Sales needs someone who can see the whole system, diagnose what's broken, and build something durable. That's this role. If you're energized by ambiguity, love designing operating models, and want real ownership over a function that touches every team in the company, this is a rare opportunity to define the craft at a company that takes software quality seriously. What You'll Do Define the Launch Standard: Establish what a great product launch looks like at Sentry: the gates, the playbooks, the decision rights, and the rituals. You're not inheriting a fixed process; you're authoring it. Own Feature Flag & Cohort Strategy: Bring intentionality to how Sentry uses early access programs, beta cohorts, and staged rollouts. Make sure the right customers get the right features at the right time, and that we're learning from every rollout. Orchestrate Cross-Functional Readiness: Be the central coordinator who ensures Engineering,
