About The Position

CyberArk is scaling our Identity Platform to support rapid global growth, and we’re hiring a Senior Backend Engineer who loves solving complex distributed systems challenges. You’ll work alongside senior engineers and architects onsite in Santa Clara, designing and optimizing the core services that secure millions of identities worldwide. This role is ideal for someone who cares deeply about system design, performance, and building secure, reliable backend systems that last. We welcome strong Java engineers who are excited to learn .NET.

Requirements

• You’ve designed and built large-scale, cloud-based backend systems.
• You’re fluent in .NET, or you’re a strong Java engineer willing to ramp up quickly.
• You think in terms of systems, scalability, and clean abstractions.
• You communicate clearly, enjoy collaboration, and value shipping high-quality work.
• You work effectively in a hybrid environment (2–3 days onsite in Santa Clara). (While relocation support isn’t available, we welcome candidates who are planning to move to the area.)
• 5+ years of backend engineering experience in large-scale or enterprise environments.
• Experience with distributed systems (caching, resiliency, async patterns, failover, load balancing).
• Strong understanding of API design and backend service integration.
• Experience with cloud platforms (AWS or GCP preferred).
• Familiarity with identity standards (OAuth2, OIDC, SAML) is a plus.

Nice To Haves

• Active Directory experience, performance engineering, or experience in identity/security environments.

Responsibilities

• Build and evolve distributed backend services in .NET to support global enterprise workloads.
• Architect new capabilities using cloud-native patterns and modern engineering practices.
• Improve system performance and resiliency across caching, async flows, data pipelines, and service-level behaviors.
• Lead deep debugging and profiling efforts, including load analysis and distributed tracing.
• Collaborate with platform, product, and cloud teams to influence architecture decisions.
• Mentor engineers and contribute to a high-trust, high-ownership engineering culture.
