CyberArk is building the cloud platform that secures machine identities at scale. We’re looking for a Staff Software Engineer to lead performance and reliability engineering across distributed, microservices-based systems.

In this role, you will define how system behavior is measured, tested, and improved under real-world load — building the frameworks, tooling, and standards that enable teams to deliver scalable, production-ready services.

You will operate at the intersection of quality, production engineering, and distributed systems, driving performance engineering as a core capability across the platform.

What You’ll Do

• Define and drive performance and reliability engineering strategy across cloud-native, distributed systems
• Design and build frameworks, tooling, and infrastructure for performance testing and system analysis at scale
• Establish performance baselines, SLIs/SLOs, and measurable standards across services
• Partner with engineering teams to embed performance testing into CI/CD workflows and development lifecycles
• Analyze system behavior under load and identify bottlenecks across application, infrastructure, and data layers
• Use observability data to interpret latency distributions, throughput, and failure patterns, and translate findings into actionable improvements
• Build reusable performance tooling and test platforms adopted across multiple teams
• Influence system design by advocating for scalability, resilience, and production readiness early in development
• Drive adoption of performance and reliability practices across teams, acting as a technical leader and subject matter expert
• Mentor engineers and contribute to raising the bar for system-level thinking and engineering quality

#LI-KR1

#LI-Hybrid

• 8+ years of experience in software engineering, SDET, performance engineering, or backend engineering roles
• Strong coding skills in Go, Java, or Python, with experience building frameworks or system-level tooling
• Proven experience designing and building performance testing systems, platforms, or frameworks
• Deep understanding of:
  • performance testing methodologies (load, stress, soak, spike)
  • workload modeling and traffic patterns
  • latency (p50/p90/p99), throughput, and system behavior under load
• Experience working with distributed systems and cloud-native architectures
• Strong experience with observability platforms (Prometheus, Grafana, Datadog, etc.)
• Experience integrating performance testing into CI/CD pipelines at scale
• Solid understanding of Linux systems and networking fundamentals (TCP/IP, DNS, HTTP/S)
• Experience driving technical direction or influencing engineering practices across multiple teams

Nice to Have

• Experience building or extending custom load testing frameworks (k6, Locust, Gatling, etc.)
• Experience with containerized environments and orchestration (Kubernetes)
• Familiarity with cloud infrastructure behavior under load (autoscaling, load balancing, storage systems)
• Experience in SaaS or security-sensitive systems
• Exposure to PKI, certificate lifecycle management, or identity systems
• Experience with Infrastructure as Code (Terraform, Ansible)

What Sets You Apart

• Ability to operate across teams and influence engineering direction
• Strong system-level thinking across application, infrastructure, and data layers
• Proven ability to drive adoption of technical practices at scale
• Ability to translate performance insights into engineering decisions and product impact
• Clear communication of complex system behavior to both technical and non-technical stakeholders

Why This Role

• Define and scale performance engineering across a high-impact cloud platform
• Work on distributed systems operating at enterprise scale
• Influence architecture and engineering practices across multiple teams
• Partner with experienced engineers solving complex system challenges
