Crowdstrike

Overview

The Falcon Secure Access (FSA) team at CrowdStrike is expanding. As a Senior Software Engineer on our team, you will architect and deliver a next-generation secure access platform that converges Zero Trust Network Access with browser-native security.

About Crowdstrike

As a global leader in cybersecurity, CrowdStrike protects the people, processes and technologies that drive modern organizations. Since 2011, our mission hasn’t changed — we’re here to stop breaches, and we’ve redefined modern security with the world’s most advanced AI-native platform.

Requirements & Eligibility

• 5+ years of industry experience building high-performance software products, preferably in cybersecurity
• Strong networking fundamentals — deep understanding of communication protocols (TCP/IP, TLS, WebSockets, HTTP/2), proxy architectures, and tunneling mechanisms
• Proven backend expertise — experience designing and developing high-scale microservices in Node.js / TypeScript / Python / GO / C++
• Proven experience utilizing AI technologies to enhance decision-making, streamline workflows and processes, improve efficiency and drive business outcomes
• Hands-on experience with proxy and secure communication — WebSocket implementations, forward/reverse proxies, MITM inspection, and encrypted channel design
• Familiarity with encryption and secure communication — TLS/mTLS, certificate management, key exchange protocols, and secure session handling
• Experience with client-agent development — building complex, efficient client-side agents with reliable server communication
• Cloud platform experience — AWS, GCP, or Azure, with understanding of on-premises and hybrid infrastructure

Key Responsibilities

• Design and build ZTNA infrastructure — implement zero-trust access policies, secure tunneling, and identity-aware network routing that replaces traditional VPN architectures
• Develop advanced networking solutions — build and optimize proxy communication layers, WebSocket-based transport, and encrypted client-to-server channels that handle millions of concurrent connections
• Architect high-scale backend systems — design distributed microservices for policy enforcement, real-time threat detection, and access control at scale using Node.js / TypeScript
• Implement secure client-server communication — design highly secured agent-to-cloud architectures with certificate pinning, mutual TLS, and encrypted tunneling protocols
• Build browser-native security components — develop browser extensions and agents (Chrome, Edge, Firefox etc.) that enforce data protection, prevent data leakage, and provide granular visibility and control
• Own features end-to-end — from design through delivery, including deployment and monitoring
• Influence architecture and roadmap — play a key role in architectural decisions, building toward an efficient distributed zero-trust architecture
• Research and develop — drive new initiatives and POCs in zero-trust access domains and browser security
