  • Experience integrating complex systems across space and ground segments.
  • Experience developing and deploying OCI‑compliant containers.
  • Proficiency with Podman and Kubernetes for container orchestration.
  • Hands-on experience with GitLab DevSecOps pipelines.
  • Familiarity with secure software development lifecycle (SSDLC) practices for high‑security environments.
  • Demonstrated ability to lead small engineering teams and mentor junior engineers.
  • Excellent communication skills, including the ability to articulate complex technical concepts to customers, subsystem leads, and internal leadership.
  • Proven ability to drive technical decisions and maintain engineering rigor under schedule and mission pressures.
