About The Position

We are seeking a Cyber Security Engineer to design, build, and evolve our internal enterprise browser platform. This role involves delivering secure, scalable, and policy-driven browser capabilities that integrate deeply with our endpoint security and network security ecosystem. The focus will be on network integrations, endpoint posture enforcement, identity-aware access, and secure application delivery within a large-scale enterprise environment.

Requirements

6+ years of experience in software engineering focused on systems or platform development in enterprise environments.
6+ years of experience using one or more system-level programming languages (for example, C++, Rust, Go, Java or similar object-oriented languages) to build production services or components.
6+ years of experience working with network protocols (for example, HTTP/S, TLS, proxies) and authentication and authorization flows in the context of enterprise security or access-control systems.
4+ years of experience integrating with endpoint security or device management solutions and with APIs or software development kits (SDKs) from security or infrastructure platforms.
Demonstrated ability to debug and resolve complex issues across distributed systems, including browser runtime, operating systems, and network and identity layers.
Strong skills in secure coding practices, code reviews, and use of tooling (for example, debuggers, profilers, and observability platforms) to improve quality and reliability.
Bachelor’s degree or degree in Computer Science, Engineering or related field or equivalent combination of education, related experience and/or military experience.
Must currently possess valid and unrestricted U.S. work authorization. Individuals with temporary visas including, but not limited to, F-1 (OPT, CPT, STEM), H-1B, H-2, or TN, or any candidate requiring sponsorship, now or in the future, will not be considered for this role.

Nice To Haves

Experience working on browser-based products or Chromium-based architecture, including extensions, embedded frameworks, or custom browser components.
Background in endpoint security, application security, or network security, with familiarity using Zero Trust or identity-aware access models.
Experience with Windows and/or macOS at the system integration level, including low-level hooks or security integrations.
Experience operating software in highly regulated environments with compliance and audit requirements.

Responsibilities

Design, develop, and maintain enterprise browser features and services that support secure, policy-driven user experiences.
Build integrations between the browser and endpoint security and device management platforms, network security solutions, and identity and access management systems.
Implement browser-level security controls, including session isolation, access enforcement, authentication and authorization workflows, and data-protection policy enforcement.
Develop services and components that collect and act on device posture and endpoint signals, user identity, and access context to support adaptive security decisions.
Write clean, secure, and highly maintainable production code for browser runtimes, operating system integrations, and backend services.
Troubleshoot and debug complex issues across browser runtime, operating system integrations, and network and identity layers to restore service quickly and prevent recurrence.
Collaborate with product managers, security architects, and platform engineers to deliver features end-to-end, participate in design reviews, and contribute to performance, reliability, and scalability improvements.
Maintain clear documentation for implementation details, application programming interfaces (APIs), and integrations to support ongoing operations and future enhancements.
