Were growing and looking to hire a Backend Software Engineer who embodies our core values: People First, Customer Obsession, Strive for Excellence, and Integrity.
As a Backend Software Engineer, you will be a key contributor to the development of our industry-leading secure remote access solution. In a world where critical infrastructure is increasingly connected, you will help build the bridge that allows safe, monitored, and frictionless access to sensitive industrial environments. You will tackle complex identity management and high-availability systems where security and performance are equally paramount.
Responsibilities:
As a Backend Software Engineer, your impact will be:
Take full ownership over features, from product design to deployment, including whole feature architecture.
Drive Technical Ownership: Design, develop, and maintain robust secure access features, ensuring seamless integration between IT and OT networks.
Architectural Evolution: Implement and optimize scalable, high-performance gateway and proxy architectures that support global enterprise scales.
Cross-Functional Collaboration: Partner with Product Management and Security Researchers to implement Zero Trust principles and advanced session monitoring capabilities.
Maintain Code Excellence: Promote best practices in code quality, security protocols, and system resilience across the company's code infrastructure.

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.

You'll 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: you'll design and implement advanced proxy communication, secure tunneling, and identity-aware routing - all operating at the browser's core to deliver holistic protection including DLP, insider threat detection, SaaS security, and continuous zero-trust verification.

What You'll 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 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

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