About the Job

Requirements

  • U.S. citizenship is required due to the nature of assigned customers.
  • Foundational understanding of artificial intelligence and machine learning technologies, and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within the functional domain.
  • At least 5 years of experience in Site Reliability Engineering, Production Engineering, or Systems Engineering operating high-scale, low-latency production platforms.
  • Ability to write and debug executable code live in Python, Go, or Bash, covering core logic and data structures, and hands-on experience writing Ansible playbooks and tasks for infrastructure automation.
  • Deep knowledge of Linux operating system internals and kernel troubleshooting, including inodes, open file descriptors, process states, and analyzing df versus du storage discrepancies.
  • Comprehensive understanding of networking protocols and packet-level analysis, including DNS resolution workflows, TLS handshakes, TCP/IP mechanics, and packet captures using tcpdump.

Responsibilities

  • Maintain high availability across large-scale bare-metal Linux/BSD fleets, Kubernetes clusters, and custom routing stacks in partnership with Engineering and Networking teams.
  • Lead full-cycle incident response by conducting cross-stack troubleshooting using low-level operating system and network tools, including strace, lsof, tcpdump, iostat, vmstat, and gdb; maintain high availability across large-scale bare-metal Linux/BSD fleets and Kubernetes clusters.
  • Automate infrastructure lifecycle management, service provisioning, configuration workflows, and release deployments using Ansible, Python, and Go; quantify operational toil and convert recurring manual work into durable, version-controlled, testable automation, tracking reduction as an engineering outcome.
  • Own end-to-end telemetry, including metrics, logs, and traces, using Prometheus and OpenTelemetry ecosystems; define and enforce service-level objectives and error budgets to reduce alert noise.
  • Perform architectural reviews, operating system and kernel upgrades, capacity and performance tuning, and strict continuous integration/continuous delivery validation before production rollouts; embed operability standards, including telemetry, rollback safety, and service-level objective readiness, into service design from the start.

Desired Qualifications

  • Hands-on experience operating and managing FreeBSD/BSD operating systems in production.
  • Expertise running, scaling, and troubleshooting Kubernetes clusters in high-traffic, low-latency environments and workflow orchestration platforms such as Temporal or similar.
  • Deep experience with Prometheus and OpenTelemetry ecosystems, or leveraging artificial intelligence and machine learning frameworks/AIOps tools for automated root-cause analysis.
