Our systems run in production at global scale and are used to build millions of real applications.\nSince our public launch, we've crossed $130M in ARR and grown to over 10M users across 190+ countries, who have built 12M+ applications on Emergent. We're backed by Creaegis, Claypond, Sentinel Global, Khosla Ventures, SoftBank, Google, Lightspeed, Prosus, Together, and Y Combinator.\nWe're solving the hard part of AI-driven software creation: correctness, reliability, security, and scale in real production systems. The team is built by repeat founders, Olympiad medalists, IIT & IIM alumni, and leaders from Google, Amazon, and Dropbox.\nWe're hiring builders who want ownership, speed, and impact at global scale.\nThe Role:\nEmergent runs a massive, multi-tenant, AI-driven execution environment where code is generated and executed continuously. You will secure the infrastructure that powers autonomous software creation.\nWhat You'll Do:\nWhat You’ll Do\nSecure AI-generated applications at scale\nDefine security patterns for applications generated by AI agents\nEnforce guardrails across auth, data access, APIs, and business logic\nBuild frameworks to ensure secure-by-default app generation\nDesign “secure generation” systems\nWork directly with AI/agent pipelines to prevent insecure code from being produced\nBuild validation layers for generated code (static + semantic)\nDetect prompt injection and adversarial input patterns\nOwn application threat modeling\nIdentify vulnerabilities in dynamic app creation flows\nAnalyze risks in multi-tenant user-generated environments\nBuild reusable threat models for agent-driven systems\nBuild developer-facing security primitives\nAuth systems, permission frameworks, secure SDKs\nSecure API gateways and rate limiting\nInput/output validation layers for LLM-driven flows\nRed team AI-generated apps\nBreak applications generated by Emergent agents\nIdentify systemic weaknesses vs one-off bugs\nFeed learnings back into generation systems\nWhat We’re Looking For\n5-10+ years in Application Security \nStrong coding ability (Python, JS/TS, backend systems)\nDeep understanding of:\nOWASP Top 10\nAuth & session management\nAPI security\nInjection & sandbox escape vectors\nExperience working closely with product/engineering teams\nWhat Sets You Apart\nYou think in systems, not vulnerabilities\nYou want to prevent insecure code from ever existing\nExperience with:\nAI/LLM systems\nPrompt injection & output validation\nSecure code generation systems\nWhy Emergent\nBuild security for AI systems that build software\nOperate at global scale (millions of apps, millions of users)\nWork directly with founders and core engineering\nSolve problems that don’t exist anywhere else yet","description_format":"text","description_chars":2882,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Application
