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 Do

Secure 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

What We’re Looking For

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

What Sets You Apart

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

Adapt your resume

List these exact terms on your resume: AI agents, Application Security, Security, Threat Modeling, and LLM Security. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them. A tool named with nothing behind it rarely survives a human read.
Lead with what you built, trained or shipped. This role is judged on the AI system itself, not the tools around it.
