👋 WELCOME TO GLIDE! At Glide we're reimagining the banking experience for the modern world. Our agentic platform empowers legacy financial institutions, like community banks and credit unions, to deploy specialized agents that help the bank grow its deposit and loan portfolio. In just the last year, we've raised $20M and grown revenue 500%, and we're accelerating. We're looking for our first Talent Engineer to help us hire the people who will carry that mission to thousands of banks. As Glide's first Talent Engineer, you will build the recruiting engine that doubles our team to more than 100 people. Think of it as a hybrid of recruiter and engineer: you'll design and run the software, automations, and data pipelines behind how we hire, so that finding and winning great people becomes a system we can scale instead of a manual grind. You'll decide what to build and what to buy. Some of it is a polished tool worth paying for. Plenty of it is a few lines of Python and an API call you wrote yourself. The instinct for which is which, and a bias toward the leaner, more controllable option, is what we're hiring for. This is a rare opportunity to join an early-stage company and help create a new standard for how a company hires. What You'll Do: Turn our network into our pipeline: Our best hires will come from people our team and investors already know. You'll build the systems that surface those second and third-degree connections at scale across LinkedIn, GitHub, operator communities, and referral graphs, so warm introductions happen on purpose instead of by luck. Automate sourcing and outreach: Stand up and tune the agents and sequences (Juicebox, Clay, Ashby, and whatever you build yourself) that find, enrich, and reach candidates faster and far more personally than any one person could by hand. Put AI on the first read: Design the LLM-assisted screening that filters for fit before a human spends a minute on it. You own the prompts, the scoring logic, and the quality che

About the Team Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity. The Security team protects OpenAI’s technology, people, and products. We are technical in what we build but operational in how we execute, and we support every product and research effort at OpenAI. Our tenets include prioritizing for impact, enabling researchers and developers, preparing for future transformative technologies, and fostering a strong, collaborative security culture. About the Role OpenAI is seeking a Principal Software Engineer to join the Infrastructure Security (InfraSec) team. InfraSec safeguards the core of OpenAI’s research and production environments: GPU supercomputing clusters, multi-cloud infrastructure, datacenters, networking, storage, and the critical services that power our frontier AI models. Our charter spans everything from bare-metal hardware and firmware to Kubernetes clusters, service meshes, and the data pathways that carry highly sensitive model weights and user data. As a Principal Software Engineer, you will set technical direction and drive execution of critical foundational services, such as authentication systems, egress/ingress proxies, access brokers, and key management platforms, that demand high standards of reliability, scalability, and software craftsmanship. These systems form the security backbone of OpenAI’s customer and supercomputing environment and must remain robust under intense scale and adversarial pressure. In this role, you will: Own the architecture and roadmap for one or more core security services (e.g., authN/Z, policy enforcement, secure proxies, key management), taking them from design to rollout to long-term operation. Design and implement planet-scale security systems that provide strong guarantees across hardware, operating systems, Kubernetes, networks, and CI/CD: balancing security, reliability, latency, and developer ergonomics.

About the Team Security is foundational to OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity. The Security organization protects OpenAI’s technology, people, and products by building and operating deeply technical systems that must work reliably at massive scale. Our work underpins OpenAI’s commitments around safety, privacy, and security across research, products, and emerging platforms. The Host Assurance team exists to make bare metal and VMs dependable & scalable foundations for OpenAI: secure by default, verifiable in practice, and resilient across providers and operating models. We operate at the trust boundary between hardware and cloud-scale orchestration, ensuring that hosts are eligible to safely run workloads with predictable security properties and auditability. About the Role OpenAI is seeking a Software Engineer, Host Assurance to build and operate the services, APIs, and host software that establish and maintain trust in our compute infrastructure. You will own production software from design and implementation through testing, rollout, observability, and operation. Your work will support capabilities such as machine identity, certificate issuance and enrollment, secure bootstrap, and host attestation across bare-metal and VM environments. Success in this role requires strong technical judgment, the ability to reason across software and host-system boundaries and learn unfamiliar parts of the stack, and a practical mindset for building systems that are secure, reliable, and usable in fast-moving production environments. The systems you build will sit on the critical path of OpenAI’s frontier infrastructure investments and will directly shape how large amounts of compute are brought online - securely, responsibly, and at global scale - underpinning long-lived commitments around privacy, security, and reliability. You will partner closely with infrastructure, research, and confidential computing initiatives—inc

At Vanta, our mission is to help businesses earn and prove trust. We believe that security should be monitored and verified continuously, and we empower companies to practice better security and prove it with ease. Vanta has a kind and talented team, and while some have prior security experience, many have been successful at Vanta without it. You will build the operating system for EPD — the systems, agents, and practices that make engineering, product, and design unreasonably effective at delivery, with Jira as the substrate. The EPD Systems team is building the infrastructure Vanta's engineering, product, and design organization depends on to understand itself and operate well. We're constructing three interlocking layers: sources of truth at the foundation, a shared interpretive layer that reasons across all of them, and the operating system that makes the work itself legible. This role owns the operating system. This is not a traditional PMO or status-reporting role. You build — agents, automation, workflow design, and the practices that make teams want to use the system rather than route around it. What you’ll do as a Senior Systems Designer at Vanta: Design and own workflow and hierarchy across engineering, product, and design in Jira Make sure Jira reflects real practice, and real practice reflects what needs to show up in Jira — in both directions Build the agents and automation that run the system yourself, with AI as part of how you work Drive adoption: go to the teams whose practice doesn't match the substrate today and change that — through conversation, well-built artifacts, or clear instruction that works without you in the room Understand delivery breakdowns at the mechanism level and build fixes that address the root cause, not the symptom Build alongside teammates who are growing into more technical work — raise their ceiling, not just your own output How to be successful in this role: You build and ship, recently, with AI as part of how you work.
