What You'll Do

• Performance & Capacity: Profile and optimise services handling large-scale data pipelines; perform capacity planning for storage and compute-intensive workloads. Work with squads to establish performance benchmarks and expectations.
• Collaboration: Partner closely with backend and ML engineers to improve deployment pipelines (CI/CD), review infrastructure changes, and champion reliability best practices.
• Reliability & Availability: Define and own SLIs/SLOs/SLAs for critical services; build alerting, runbooks, and incident response processes; lead postmortems with a blameless culture.
• Infrastructure & Cloud: Design, deploy, and maintain cloud infrastructure on GCP and AWS; manage Kubernetes clusters, networking, and storage at petabyte scale.
• Automation & Tooling: Work to improve developer productivity and guide and review automation and tooling efforts across the engineering group.
• Observability: Instrument services with distributed tracing, logging, and metrics (Prometheus, Grafana, OpenTelemetry, Datadog or similar); build infrastructure, define best practices and work with each squad to ensure every service is observable before it goes to production.

Requirements

• Hands-on SRE, DevOps, platform engineering experience or similar in a production environment.
• Strong fundamentals in designing, building and maintaining resilient distributed and/or high performance systems.
• Solid understanding of networking, operating systems and database technologies.
• Experience with observability fundamentals — metrics, logs, traces, and alerting.
• Comfortable with on-call rotations and incident management.

Nice to Haves

• Familiarity or willingness to work with the tech stack including Python and Rust (backend), TypeScript and React (frontend), Kubernetes, and GCP.
• Open to learning new technologies across various domains.
