About This Role 

As a Principal Site Reliability Engineer, you will help set the technical vision and strategy for reliability across spacecraft, ground systems, and enterprise platforms. You’ll define standards, mentor senior engineers, and drive cross-organizational initiatives to ensure systems are highly operable, secure, and mission-ready. This role combines deep technical expertise with the ability to influence architectural direction at the company level. 

 

Responsibilities 

• Lead and contribute hands-on to the deployment, maintenance, and operations of mission-critical applications and infrastructure supporting spacecraft, ground systems, and company-wide platforms. 

• Design, execute, and manage highly scalable, reliable, and operable software and infrastructure platforms, applying Infrastructure as Code (IaC) principles to drive automation, consistency, and repeatability across Kubernetes environments. 

• Collaborate closely with software and hardware teams to align reliability best practices, CI/CD pipelines, and compliance with their workflows, enabling faster, more secure deployments for mission-critical systems. 

• Anticipate and address reliability risks, capacity challenges, and performance bottlenecks; develop long-term strategies in partnership with leadership. 

• Rotate through the team’s on-call schedule to keep critical systems healthy and responsive. 

• Occasionally travel to customer sites and other Varda locations to troubleshoot, deploy, or test critical infrastructure.
