Replit is the agentic software creation platform that enables anyone to build applications using natural language. With millions of users worldwide, Replit is democratizing software development by removing traditional barriers to application creation. About The Role Replit is where millions of people learn to build software - and our documentation and learning content are where they get going or give up. We're taking ownership of that experience, and we're looking for a Learning Experience Creator who can make it worthy of the product: someone who turns product knowledge into experiences people actually use - clear written docs, guided learning, short video, interactive experiences - findable at the moment of need, accurate every time, and genuinely enjoyable. You're a learning-experience creator first. You understand how people actually learn a product - what they're trying to accomplish, where they get stuck, what format serves each moment - and you move fluidly between writing a crisp help article, designing a hands-on walkthrough, and producing a short video. Underneath it all, you're a storyteller: you know how to earn attention in the first few seconds, hold it against real-world attention spans, and make ideas stick - and sometimes make something people can't help but share. You're also a builder: unafraid to try new formats and experiment, you read the data and listen to customers, and you continually improve and evolve with speed as our product evolves. You'll turn complex things into simple, useful experiences, and you'll own how well they land. The Mission : help every user - external customers and internal teams - self-serve to reach their creative and business goals, with content so good, so current, and so findable that they don't need to open a ticket. Success looks like real ticket deflection, faster activation, and high CSAT. What You'll Own New documentation and learning content. You'll populate our documentation and learning surfaces with new, acc

In this critical role, you will design, implement, and maintain the runtime defense systems, guardrail frameworks, and sandboxing architectures that govern AI agents executing code, invoking tools, and reasoning across our platform. You will be a key technical contributor—leading high-impact AI security initiatives and bridging the gap between non-deterministic AI behavior and rigorous cybersecurity controls for both engineering and executive leadership. What You'll Do AI Agent Security Strategy & Technical Execution AI Agent Security Blueprint: Define the long-term vision and architectural patterns for securing autonomous agent workflows, Model Context Protocol (MCP) integrations, multi-turn reasoning loops, and multi-agent coordination. Runtime Guardrails & Policy Enforcement: Architect and deploy dynamic input/output guardrail systems, semantic firewalls, and real-time intent verification filters to prevent goal hijacking, system prompt leaks, and indirect prompt injections. Agent Execution & Tool Sandboxing: Partner with Infrastructure and AppSec teams to design secure, short-lived, micro-isolated environments (e.g., microVMs, WebAssembly, container sandboxes) where agents can dynamically execute code, run shell commands, and interact with host operating systems safely. Agentic Threat Modeling & Red Teaming: Conduct specialized threat modeling against non-deterministic systems. Lead automated and manual AI red-teaming initiatives to uncover vulnerabilities in RAG context pipelines, vector stores, and tool-calling interfaces. Identity
