Each environment is a working replica of a real system with an attack planted inside it. A verifier decides whether the agent held up.\nAll of it runs on AgenticVerse, our platform for building, running, and reviewing RL environments. AgenticVerse is a full-fledged, production-grade SaaS application. A large and fast-growing community of researchers works in it every day.\nWe're looking for a Senior Full-Stack Engineer to own AgenticVerse as a product, and to build the digital twins our environments are made of.\nWhat you'll do\nAgenticVerse\nOwn the AgenticVerse application end to end: frontend, backend, data model, and APIs\nBuild the workflows researchers live in: authoring tasks, launching runs, managing gyms, and reviewing results\nMake a run readable at a glance: traces, verifier results, and where the agent went wrong\nHold a production bar: performance, reliability, access control, and observability as the user base grows\nTake features from design to production, and talk to the researchers who use them\nDigital twins\nBuild digital twins of real products: web apps an agent can't tell apart from the real thing\nBuild the full stack behind each one: the UI, a real API backend, and the state that persists across a run\nExpose every action the agent takes as an event the verifier can grade\nRequirements\nWhat we're looking for\n6+ years as a full-stack engineer, building production SaaS\nBSc in Computer Science or a related field, preferably from a leading university\nStrong TypeScript and React, and a backend language (Python preferred)\nExperience designing APIs and data models for multi-user applications\nProduction experience with Docker and cloud infrastructure (AWS preferred)\nHigh autonomy in an undefined space. You take a loose problem and come back with working code\nFluent written and spoken English\nAdvantage\nHands-on AI engineering: building with LLMs, agents, or evaluations\nExperience building developer tools or internal platforms\nExperience with Kubernetes\nBackground in security, red teaming, or trust and safety\nAbout Alice\nAlice is a trust, safety, and security company built for the AI era. We safeguard the communicative technologies people use to create, collaborate, and interact- whether with each other or with machines.\nIn a world where AI has fundamentally changed the nature of risk, Alice provides end-to-end coverage across the entire AI lifecycle. We support frontier model labs, enterprises, and UGC platforms with a comprehensive suite of solutions: from model hardening evaluations and pre-deployment red-teaming to runtime guardrails and ongoing drift detection.\nAlice is widely considered a global leader in online safety and AI security.
