About the Role:

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.

Youll build the core systems that enable users to seamlessly and securely access internal sites private applications and cloud resources directly from the browser without legacy VPNs or remote desktops while enforcing real-time protection against zero-day exploits phishing data exfiltration and unauthorized access.

This role sits at the intersection of network engineering and browser security: youll design and implement advanced proxy communication secure tunneling and identity-aware routing all operating at the browsers core to deliver holistic protection including DLP insider threat detection SaaS security and continuous zero-trust verification.

What Youll Do:

• 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 / 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

• Collaborate cross-functionally work with security researchers product and platform teams across multiple locations to solve complex problems

What Youll Need:

• 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 / 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

• Strong research and debugging capabilities ability to dive deep into protocol-level issues browser internals and network traces

• BS or MS in Computer Science or related engineering discipline

• Proactive problem-solver with attention to detail and a team-oriented mindset

Bonus Points:

• Network security background experience with network-layer security firewalls NAC SD-WAN or SASE architectures

• ZTNA / Zero Trust experience familiarity with zero-trust principles identity-based access micro-segmentation or existing ZTNA products

• EDR/endpoint security knowledge experience integrating with endpoint detection and response platforms

• Browser internals expertise Chromium internals browser extension/plugin development or web platform APIs

• OS internals and low-level networking understanding of OS network stacks socket programming or kernel-level packet handling

• Containerization and orchestration Kubernetes self-contained deployable agents on-prem components
