Job description

The Aerospace Corporation is the trusted partner to the nation’s space programs, solving the hardest problems and providing unmatched technical expertise. As the operator of a federally funded research and development center (FFRDC), we are broadly engaged across all aspects of space— delivering innovative solutions that span satellite, launch, ground, and cyber systems for defense, civil and commercial customers. When you join our team, you’ll be part of a special collection of problem solvers, thought leaders, and innovators. Join us and take your place in space.

The Digital Innovation Division (DID) is accountable for integrating strategies, providing governance, and managing internal investments that form the foundation of Aerospace’s digital innovation and transformation. The DID Mission IT pillar supports engineering teams across Aerospace by delivering top-tier IT engineering and IT support services tailored to meet the unique needs of our engineering community.

Mission IT Operations is seeking a skilled Site Reliability Engineer with deep expertise in Kubernetes, Linux, programming, and automation. In this role, you will be responsible for developing and maintaining both on‑premise and cloud‑based Kubernetes clusters that form the core of an overall Platform as a Service (PaaS), providing essential support to our engineering team.

As part of a multidisciplinary platform and infrastructure team, you will manage multiple Kubernetes clusters used for technical analyses of space launch telemetry analysis and modeling and simulation, as well as for Artificial Intelligence (AI) Large Language Model (LLM) training and inference services. Collaborating closely with rocket scientists and engineers, you will contribute to the development of innovative solutions to complex challenges within the space enterprise, supporting critical national space assets.

Work Model: This is a full‑time position based in El Segundo, CA which requires 100% onsite work.

• Frequent full security patching of all layers of Kubernetes infrastructure while maintaining very high uptime.
• Ownership and engineering responsibility of production AWS and Kubernetes services.
• Identifying and resolving full Kubernetes stack engineering problems independently.
• Ensuring successful real‑time analysis of telemetry data from space launch partners, such as SpaceX, United Launch Alliance (ULA), and Blue Origin.
• Providing after‑hours support for Kubernetes infrastructure troubleshooting during launch events.
