About the Role
Responsibilities:
As a founding member of our Infrastructure Security team, you will be responsible for leading broad-scope initiatives to harden our infrastructure against sophisticated threat actors. Design and implement the core infrastructure that supports our applications, services, and large language model training and inference pipelines at scale. Our infrastructure is home to some of the most valuable intellectual property in the world - including some of the largest language models to be found anywhere - and it will be your responsibility to ensure our systems operate reliably and securely in the presence of malicious adversaries.

Implement secure build artifact handling and deployment flows
Integrate CI/CD pipelines with infrastructure to automate and secure deployments
Requirements:
Competitive candidates will have:
At least 5 years of experience with infrastructure security
Experience working with Kubernetes and Docker
Familiarity with cloud environments such as GCP or AWS
Ability to understand and contribute code to complex codebases
Familiarity with various SSH key management approaches
Deep understanding of service mesh technologies such as Istio, linkerd, or GCP Anthos
Understanding of common CI/CD-based workflows
Proficiency in Linux-based server environments with a high degree of comfort on the Linux CLI
Experience architecting secure system designs to meet product requirements at scale
Familiarity with zero trust concepts
A demonstrated ability to work autonomously to identify and resolve problems independently
Outstanding candidates will have one or more of the following:
Experience with common web application and web service design patterns
Familiarity with Helm for managing Kubernetes deployments
Previous experience in a technology startup
You will be a good fit if you are proactive and have a “get things done” mindset. Given our current pace of growth and load on our systems, most people have had a significant impact during their first week at the company.
