Job Description

Join a team of senior engineers operating in a large-scale, multi-cloud production environment supporting tens of thousands of enterprise customers worldwide. This is not a typical SRE role — you'll work at the core of a complex, high-impact system alongside experienced DevOps professionals in a fast-paced, cybersecurity-focused organization.

Job Responsibility

  • Own and operate large-scale, global production environments across multiple cloud providers (GCP, AWS, Azure)
  • Actively monitor, investigate, and resolve incidents triggered by automated alerting systems (PagerDuty / Incident Response)
  • Drive end-to-end troubleshooting across complex, distributed systems with high context switching
  • Design, deploy, and improve monitoring and observability systems (e.g., Prometheus, Grafana) — not just react to alerts
  • Collaborate closely with internal teams (CX, CS, Engineering) to ensure system reliability and performance
  • Work hands-on with modern DevOps and infrastructure tools including Kubernetes, Terraform, CI/CD pipelines, and GitOps workflows
  • Develop and maintain automation and tooling (primarily in Python)
  • Gain deep understanding of system architecture and interconnected services
  • Contribute to a culture of operational excellence in a high-scale, high-availability environment
  • Champion asynchronous communication, documentation, and tooling standards to ensure seamless collaboration across time zones and fully distributed teams

Requirements

  • 5+ years of experience in SRE roles in production environments at scale
  • Strong hands-on experience with Kubernetes and Terraform
  • Strong hands-on experience with at least one major cloud platform (GCP or AWS required)
  • Experience building and configuring monitoring systems (e.g., Prometheus, Grafana)
  • Familiarity with CI/CD and GitOps tools (GitLab CI, GitHub Actions, Jenkins, Flux)
  • Proficiency in Python for scripting and automation
  • Proven success in a fully remote or distributed team environment, demonstrating strong self-management and time organization
  • Strong troubleshooting and problem-solving skills with a passion for incident handling
  • Ability to work in fast-paced environments with high context switching
  • Highly responsive, proactive, and ownership-driven
  • Strong collaboration and communication skills
  • Curious mindset and eagerness to learn
