Senior Software Engineer - Infrastructure Security

About this role

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 $100M 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:

Secure Multi-Tenant Execution Environments

• Design sandboxing strategies for untrusted code execution

• Prevent container escapes, privilege escalation, and lateral movement

• Build isolation at compute, network, and storage layers

Own Cloud Security Architecture

• Harden AWS/GCP infrastructure across IAM, VPCs, secrets, and workloads

• Design zero-trust systems across services

• Build secure service-to-service communication

Runtime Security and Detection

• Build detection systems for abnormal execution patterns, malicious workloads, and data exfiltration attempts

• Integrate logging, SIEM, and real-time alerting

Secure CI/CD and Agent Pipelines

• Protect build systems and deployment pipelines

• Prevent supply chain attacks in AI-generated code

• Ensure integrity of artifacts

What We're Looking For:

• 5 to 8 years in Cloud or Infrastructure Security

• Deep experience with AWS/GCP, Kubernetes, containers, and IAM and secrets management

• Strong understanding of container security, network security, and runtime protection

What Sets You Apart:

• Experience with sandboxed execution environments, serverless or ephemeral compute, and high-scale multi-tenant systems

• You think like: "What happens when millions of unknown programs run on my infra?"

Why Join Us:

• Build security for AI systems that build software

• Operate at global scale with millions of apps and millions of users

• Work directly with founders and core engineering

• Solve problems that don't exist anywhere else yet

Benefits and Perks:

• Daily Meals: Lunch and Dinner provided

• Family Insurance: 5 Lakhs worth of coverage for you and your family

• Unlimited Paid Time Off: Take the time you need to recharge and come back refreshed

• Flexible Working Hours: Work arrangements that fit your life and commitments

Let's build the future of software together.
