STLabs is an AI service management platform that resolves employee requests end-to-end, grounded in a living model of the enterprise. This matters because we're able to resolve requests with full context - the people, systems, services, and policies that define how an organization actually runs. Requests that used to take days of back-and-forth resolve in minutes, right where employees already work.
About the Role
Our platform connects to our customers' most sensitive systems and acts on their behalf, so security is core to the product. You'll work alongside our infrastructure and platform team and own how we detect, respond to, and fix security issues across our cloud, our code, and our AI agents.
We're looking for someone who wants to own:
Detection and response across our AWS and Kubernetes infrastructure
Automated vulnerability remediation, from new advisory to tested fix in hours, not weeks
AI agents that triage security alerts and patch vulnerabilities, with engineers making the final call
Secure storage, use, and rotation of the credentials our customers trust us with
Supply chain security across dependencies, container images, and CI/CD
What We're Looking For
Minimum 4 years of experience in security, infrastructure, or software engineering
Deep hands-on experience securing cloud native systems on AWS
You write production code and would rather build a small system that works than buy a large one nobody watches
What Makes Candidates Stand Out
Experience building detection pipelines or leading real incident response
Understanding of the security risks of LLM-powered systems, like prompt injection and over-permissioned agents
Daily use of AI coding agents, and opinions on how to use them safely
Having built a security function from scratch
What We Offer
Build the security foundation of an AI-first enterprise platform
The opportunity to take ownership of critical systems that scale to millions of users
A culture that values craftsmanship, autonomy, and technical excellence
Competitive compensation, equity, and benefits package
