The job, as St Labs posted it
The full text from the original posting, checked 14 Nov 2026.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
- Work from our Midtown, Manhattan office, where you'll be side-by-side with the founding team in a supportive, collaborative setting. Our team works on-site five days a week. The location is easy to reach with plenty of public transportation options.
