Secure Every Identity, from AI to Human Identity is the key to unlocking the potential of AI. Okta secures AI by building the trusted, neutral infrastructure that enables organizations to safely embrace this new era. This work requires a relentless drive to solve complex challenges with real-world stakes. We are looking for builders and owners who operate with speed and urgency and execute with excellence. This is an opportunity to do career-defining work. We're all in on this mission. If you are too, let's talk. The Team The Auth0 Platform Tools team owns the incident management tooling, Slack-based tooling, StatusPage, and local development environments that Auth0 engineers rely on every day. That includes incident.io and the services we have built around it, Statuspage, custom Slack bot applications that automate our incident response and engineering operations workflows, the customer-facing web application behind status.auth0.com, Vivaldi, and Tilt - the tools engineers use to run Auth0 locally. We are seeking an engineer to help build new features across all of these tools. Our stack is primarily TypeScript and Node.js, with a React and Next.js front end, backed by Postgres and Redis, and deployed on Kubernetes on AWS. A significant portion of our incident and engineering operations automation is built on Tines, a no-code automation platform. Prior no-code experience is welcome, but we expect you to learn Tines here and become effective with it. Current initiatives include extending our incident tooling to meet FedRAMP requirements, taking full ownership of the status page, and improving how we communicate incident status to customers. There is real room to improve along the way, from test coverage to resilience to inherited technical debt. We build for two audiences: Auth0 engineers, who depend on our tooling every day, and Auth0's customers, who rely on the status page during incidents. We are looking for an engineer who cares about both and enjoys working wi

A World-Changing Company Palantir builds the world’s leading software for data-driven decisions and operations. By bringing the right data to the people who need it, our platforms empower our partners to develop lifesaving drugs, forecast supply chain disruptions, locate missing children, and more. The Role Palantir’s software forms the operating system for the militaries of the United States and her allies, driving outcomes and enhancing capabilities across the full spectrum of operations, intelligence, and support activities. Our defense applications are the tip of that spear, powerful tools used daily by thousands of soldiers, sailors, airmen, and marines to perform critical work at home and abroad from the Pentagon to the front lines. The engineers who build, maintain, and extend these applications are responsible for wielding the immense technical potential of Palantir’s data modeling and AI platforms to create exquisite domain-specific workflows and interfaces that modernize, extend, and revolutionize the capabilities of the warfighter. This is a front-end engineering role focused on marrying Palantir’s Foundry and AIP platform technologies, application specific backend services, and modern web technologies with domain expertise. These teams are nimble and select the right tool for the task in front of them rather than adhering to a rigidly defined tech stack, but the most common setups are React for standard DOM rendering, Maplibre and/or Three js for geospatial and 3D rendering, Redux (in various flavors) for state management, Conjure for API management, and OSDK for interaction with the foundry platform. A rich ecosystem of in-house libraries and toolchains sit on top of that foundation to provide cross-app messaging, live data streaming, robust classification based access control, and a host of other specialized functions. Defense applications developers both consume and produce these re-usable tools as part of their core engineering role. Core R
