## Description

InfraSec operates on a preventative, enabling model: rather than acting as a manual approval gatekeeper or compliance auditor, we develop automated guardrails and platform capabilities. We integrate security directly into the platform runtime, CI/CD, and Infrastructure-as-Code (IaC) workflows so engineering teams can operate securely at scale without friction.

This role can be based out of our office or remotely in the United States.

## What You’ll Do

- Harden hosts and containerized workloads using Linux security mechanisms (AppArmor, SELinux, seccomp, cgroups) and eBPF-based tooling (Cilium, Tetragon)

- Secure containerized infrastructure across multi-cloud environments via RBAC, network policies, admission controls (Gatekeeper), and runtime threat detection

- Build and manage automated services for Cloud Security Posture Management (CSPM), workload identity, vulnerability management, and access controls across AWS, Azure, and GCP

- Write production-quality code and leverage Infrastructure-as-Code (Terraform) to version, test, and deploy security controls as code

- Build real-time security monitoring, logging, and alerting systems to detect anomalies and track security posture at Atlas scale

- Lead initiatives across their full lifecycle; from threat modeling and architectural design to implementation, rollout, and long-term production reliability

## What We’re Looking For

Minimum Qualifications:

- 10+ years in SRE, Infrastructure Engineering, or Cloud Security Engineering

- A track record of operating at Staff or Principal scope: defining technical direction, resolving cross-team ambiguity, and personally championing initiatives from conception to delivery

- Strong coding skills in Go (Golang), Python, C, C++, or Rust

- Proven track record of building and operating large-scale distributed systems or cloud platform infrastructure

- Hands-on experience using Terraform, CloudFormation, or Ansible for automated infrastructure provisioning

- Demonstrated experience owning infrastructure in Linux, Kubernetes, and at least one major cloud provider (AWS, GCP, or Azure)

Preferred Qualifications:

- Practical experience with eBPF-based security tooling (Cilium, Falco, Tetragon)

- Direct ownership of Cloud Security and Workload Identity platforms

- Multi-cloud expertise spanning AWS, Azure, and GCP

- Production exposure to low-level Linux security mechanisms (seccomp, AppArmor, SELinux, cgroups)
