Senior Software Engineer - Infrastructure Security

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.
