Kubernetes

Keeping a crawler running is not the same as keeping it productive. Queues can grow while servers look healthy, and a small change can become a fleet-wide bottleneck. On Perplexity's Crawler team, you'll improve throughput, plan capacity, and build operational reliability through safer deployments, better observability, and durable fixes.

Responsibilities

  • Operate and optimize Kubernetes workloads and supporting infrastructure for crawler services, including fetching and rendering fleets.
  • Build and maintain infrastructure as code and CI/CD pipelines, with safe rollouts, validation, and fast rollback.
  • Define SLOs and build monitoring, alerting, and observability for availability, latency, throughput, and resource saturation.
  • Own capacity planning and resource efficiency; diagnose queue backlogs, network failures, and resource bottlenecks with service owners.
  • Participate in the team's on-call rotation, lead incident response, and turn blameless postmortems into durable reliability improvements.
  • Write production software to automate diagnosis and routine remediation, with validation and approval gates for high-impact actions.

Qualifications

  • 5+ years of experience in SRE, production engineering, or infrastructure-heavy backend roles, with strong programming skills in Python, C++, Rust, or Go.
  • Hands-on experience with cloud infrastructure, production Kubernetes, infrastructure as code such as Terraform, and automated deployment workflows.
  • Strong Linux and networking fundamentals, including TCP/IP, DNS, TLS, HTTP, and load balancing.
