Job Summary

The Team

Engineering - Our engineering team is at the core of our products and connected directly to the mission of preventing cyberattacks. We are constantly innovating - challenging the way we, and the industry, think about cybersecurity. Our engineers don’t shy away from building products to solve problems no one has pursued before. We define the industry instead of waiting for directions. We need individuals who feel comfortable in ambiguity, excited by the prospect of a challenge, and empowered by the unknown risks facing our everyday lives that are only enabled by a secure digital environment.

Your Career:

Join a team of senior engineers operating in a large-scale, multi-cloud production environment supporting tens of thousands of enterprise customers worldwide.

Your Impact:

• 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.
• On call responsibilities:
  Daytime hours (12:00-20:00 CET/CEST, based on candidate location and team coverage needs)

Occasional weekends and holidays (rotation-based)

Your experience:

• 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
