Emergent builds autonomous coding agents that replace traditional software development by generating, testing, and deploying production applications directly from plain-language intent. Our systems run in production at global scale and are used to build millions of real applications.
Since 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.
We'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.
We're hiring builders who want ownership, speed, and impact at global scale.
The Role:
Emergent 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.
What You'll Do:
What You’ll DoSecure AI-generated applications at scale
- Define security patterns for applications generated by AI agents
- Enforce guardrails across auth, data access, APIs, and business logic
- Build frameworks to ensure secure-by-default app generation
Design “secure generation” systems
- Work directly with AI/agent pipelines to prevent insecure code from being produced
- Build validation layers for generated code (static + semantic)
- Detect prompt injection and adversarial input patterns
Own application threat modeling
- Identify vulnerabilities in dynamic app creation flows
- Analyze risks in multi-tenant user-generated environments
- Build reusable threat models for agent-driven systems
Build developer-facing security primitives
- Auth systems, permission frameworks, secure SDKs
- Secure API gateways and rate limiting
- Input/output validation layers for LLM-driven flows
Red team AI-generated apps
- Break applications generated by Emergent agents
- Identify systemic weaknesses vs one-off bugs
- Feed learnings back into generation systems
- 5–10+ years in Application Security
- Strong coding ability (Python, JS/TS, backend systems)
- Deep understanding of:
- OWASP Top 10
- Auth & session management
- API security
- Injection & sandbox escape vectors
- Experience working closely with product/engineering teams
- You think in systems, not vulnerabilities
- You want to prevent insecure code from ever existing
- Experience with:
- AI/LLM systems
- Prompt injection & output validation
- Secure code generation systems
Why Emergent
- Build security for AI systems that build software
- Operate at global scale (millions of apps, millions of users)
- Work directly with founders and core engineering
- Solve problems that don’t exist anywhere else yet
Skills Required

- Deep understanding of API security
- Deep understanding of injection and sandbox escape vectors
- Experience working closely with product and engineering teams
- Experience with AI or LLM systems
- Experience with prompt injection and output validation
- Experience with secure code generation systems
What We Do
Backed by Lightspeed, Y Combinator, Together Fund, and Prosus, Emergent is reimagining how software gets built. Our vision is to democratize development, enabling anyone with an idea to become a creator and making software accessible to a billion people worldwide. Our autonomous coding agents turn plain-language ideas into fully functional applications, tested, version-controlled, and deployable in minutes. What once took weeks now happens with a single click. Enterprises use Emergent to write, maintain, and test millions of lines of code autonomously, cutting development cycles from months to days. Headquartered in San Francisco, we’re led by repeat entrepreneurs with a proven track record of building successful startups, joined by a world-class team of Olympiad medalists, IIT & IIM alumni, and veterans from Google, Amazon, and Dropbox. Together, we’re building at the frontier of AI and systems engineering—shipping daily and setting new standards for AI-driven development. In just 90 days, we scaled to $15M ARR, making us one of the fastest-growing AI startups in the world, with users across 180+ countries. Join us in shaping the future of software development.
