Apex Spacecraft · Los Angeles, CA · Production · first seen 2026-09-03

About the Role

You will design, build, and operate the ground and site network infrastructure that connects Apex facilities and mission operations across both commercial and secured environments. This is a hands-on engineering role for someone equally comfortable architecting a highly available Kubernetes platform and defining the security posture that keeps it compliant. You will be a primary technical owner, setting the standards that the rest of the team builds on.

Responsibilities

  • Architect and build ground and site network infrastructure spanning commercial and secured or classified environments through the platform layer.
  • Design, deploy, and scale highly available Kubernetes clusters that support workloads across multiple security and classification levels.
  • Own the security posture of ground infrastructure, defining and enforcing controls, hardening, and compliance for sensitive government and commercial programs.
  • Build and maintain infrastructure as code using Terraform, Terragrunt, and similar tooling so that environments are repeatable, reviewable, and fast to stand up.
  • Establish observability across the ground network, including monitoring, metrics, logging, and alerting, so issues are caught before they reach a mission.
  • Design and run CI/CD pipelines and automation that streamline deployments and reduce manual, error-prone work.
  • Act as a primary site reliability engineer for ground systems, driving uptime, incident response, and reliability standards on programs where downtime is not an option.
  • Partner with security, mission operations, and program teams to translate requirements into infrastructure that is both compliant and operable.
  • Set architectural standards and mentor other engineers, raising the bar for how ground infrastructure is built at Apex.

Requirements

  • U.S. person as defined by U.S. export-control law (ITAR/EAR eligible).
  • 5+ years of experience in site reliability, infrastructure, or network engineering, with meaningful experience in aerospace, defense, satellite, or mission-critical domains.
  • Hands-on experience architecting and operating ground network or large-scale production network infrastructure.
  • Deep expertise with Kubernetes and containers, including building and scaling high availability clusters in production.
  • Strong networking fundamentals across routing, switching, segmentation, and secure network design.
  • Proven experience with infrastructure as code, CI/CD, automation, and observability tooling such as Prometheus, Grafana, or similar.
  • Working knowledge of security and compliance for regulated or classified environments.
  • Proficiency scripting and building tooling in Python, Go, or a comparable language.

Nice-to-Haves

  • Active Top Secret or Top Secret/SCI clearance.
  • Prior experience supporting classified or government space programs or standing up infrastructure across multiple classification levels.
  • Familiarity with GitOps workflows and tools such as ArgoCD, and modern observability stacks including Mimir.
