## About the role

We are seeking a hands-on Infrastructure Security Engineer to build and secure SpaceXSI's infrastructure from the bare-metal layer up through the platform and application stack. In this role, you will design, implement, and harden physical and private-cloud foundations—servers, networks, identity, and orchestration—and carry that security posture into containers, automation, and hybrid connectivity with public cloud. Found on 1752vc Careers, the job board for startup and VC roles.

## What they're looking for

- Bachelor's degree in Computer Science, Cybersecurity, or a related field
- 3–5 years of experience in infrastructure security, platform security, or related hands-on roles
- Proven experience securing bare-metal, data-center, or private-cloud environments (not cloud-only resumes)
- Hands-on experience with firmware, BMC/iDRAC/iLO, PXE/Kickstart provisioning, and hardware lifecycle security
- Strong proficiency with Puppet for configuration management and fleet hardening in production
- Strong understanding of network security concepts and protocols, including hands-on work with firewalls, segmentation, and hybrid connectivity
