Staff Engineer - Security

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.

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.

We’re looking for a Staff Security Engineer to own security across the full stack—from AI-generated applications and agent pipelines to cloud infrastructure and runtime environments.

You’ll:

• Secure AI-generated code, applications, and agent pipelines
• Design secure multi-tenant cloud & runtime environments
• Lead threat modeling, detection, and defense across application and infrastructure layers
• Build security controls for AWS/GCP, Kubernetes, containers, IAM, APIs, and CI/CD
• Defend against prompt injection, container escapes, privilege escalation, and data exfiltration
• Build scalable security frameworks and partner closely with engineering and product teams

What We’re Looking For

• 8–15+ years of security engineering experience
• Strong expertise across Application/Product Security + Cloud/Infrastructure Security
• Hands-on experience with AWS/GCP, Kubernetes, containers, IAM, APIs, and threat modeling
• Strong coding skills in Python, JavaScript/TypeScript, or backend systems
• Experience securing untrusted/user-generated code and multi-tenant systems
• Strong systems thinking and ability to drive security from architecture to implementation

Bonus: Experience with AI/LLM security, agentic systems, prompt injection, sandboxing, or large-scale execution environments.

Why Emergent

• Build security for AI systems that build software.
• Solve security problems spanning application, cloud, infrastructure, and AI systems.
• Operate at global scale across millions of applications and users.
• Work directly with founders and core engineering teams.
• Solve security challenges that are emerging with autonomous software creation.
