GRAIL is seeking a Staff Site Reliability / DevOps Engineer to lead the reliability, scalability, and security of our cloud-native platform. This role operates at the intersection of infrastructure engineering, platform strategy, and organizational leadership, supporting systems that power large-scale data processing and cutting-edge cancer detection technologies.

You will define and drive infrastructure standards across teams, represent reliability and performance in architecture decisions, and build systems that scale well beyond your direct ownership. This is a highly technical, high-impact role combining hands-on engineering with cross-functional influence and mentorship.

Onsite Expectations You will work on-site full-time at our office located in Menlo Park, California. Beginning in Fall 2026, you will work at our new headquarters in Sunnyvale, California.

Reponsibilities

Design, build, and operate highly available, fault-tolerant cloud infrastructure across AWS, GCP, and/or Azure
Architect and maintain scalable CI/CD pipelines and deployment frameworks for enterprise-grade software delivery
Lead infrastructure-as-code adoption and maturity using tools such as Terraform, CloudFormation, and Ansible
Own Kubernetes reliability across multi-cluster environments, including upgrades, scaling, and workload lifecycle management
Establish and evolve observability platforms (metrics, logs, traces) and define SLO/SLI frameworks across teams
Lead incident response for critical outages, drive root cause analysis, and implement preventative improvements
Optimize infrastructure for cost, performance, and scalability, partnering closely with engineering and finance stakeholders
Define and enforce DevOps, reliability, and security best practices across the organization
Partner cross-functionally with engineering, data, QA, security, and IT teams to design resilient systems
Mentor engineers and contribute to technical leadership through design reviews, standards, and knowledge sharing

These responsibilities summarize the role’s primary responsibilities and are not an exhaustive list. They may change at the company’s discretion.

What Success Looks Like In Your First Year

Conduct a comprehensive assessment of the current infrastructure, drive infrastructure-as-code adoption to 95%+ across critical systems, and establish clear health and reliability baselines for the Kubernetes platform
Standardize observability using modern tooling and implement an SLO/SLI framework adopted across multiple product teams, including defined SLAs for critical data systems
Strengthen security and compliance posture across cloud environments by implementing consistent baselines, launching a compliance-as-code framework, and reducing mean time to resolution (MTTR) for production incidents
Define, document, and drive adoption of engineering standards, best practices, and operational guidelines across platform and product teams
Develop and align stakeholders on a forward-looking platform reliability and infrastructure roadmap
Demonstrate measurable mentorship and technical leadership impact across the engineering organization
Evaluate and provide recommendations on emerging infrastructure needs, including support for AI/ML and advanced data workloads
