### **职位描述**
Cyberhaven 正在通过理解数据在组织中的流动方式来重新定义数据安全。我们的浏览器扩展是这一愿景的关键组成部分，使用户在与网络应用交互时能够获得可见性和控制权。我们正在寻找一位有经验的工程师，帮助构建和增强我们的扩展，确保其安全、高效，并与我们的平台深度集成。你将加入我们的浏览器扩展团队，并与端点代理和后端团队紧密合作，以在各种设备和环境中提供无缝体验。
### **你将负责**
- 使用 Manifest V3 和现代 API 为 Chrome、Edge 及其他主流浏览器设计、构建和维护一个强大的浏览器扩展。
- 实现与网页内容和后端服务安全交互的功能，确保符合安全最佳实践。
- 在多样化的环境和用户工作流程中优化性能和可靠性。
- 与端点代理和后端团队紧密合作，确保端点和服务之间紧密集成和功能一致。
- 跟踪不断变化的浏览器 API、安全标准和扩展生态系统的变化。
- 参与代码审查、测试和开发流程的持续改进。
### **你具备**
- 丰富的软件工程经验：编码、测试、调试和自动化复杂的 TypeScript/JavaScript 应用程序
- 你习惯深入研究你无法控制的第三方网页应用——检查网络流量、DOM 结构和客户端代码，以了解页面的工作原理
- 你有能力快速学习新技术，并渴望这样做——尤其是随着浏览器扩展平台和 manifest 规范的持续演进
- 你关注后台进程的正确性、性能和可靠性
- 你具备出色的沟通能力
- 你在某些时候能够独立工作，接受最少的指导
- 你能够在自己和非浏览器平台开发人员之间有效协调工作
**加分项**

### **About the Role**
Cyberhaven is redefining data security by understanding how data flows across organizations. Our browser extension is a critical component of this vision, enabling visibility and control at the point where users interact with web applications. We’re looking for an experienced engineer to help build and enhance our extension, ensuring it’s secure, performant, and deeply integrated with our platform. You’ll join our Browser Extension team and collaborate closely with both the endpoint agent and backend teams to deliver a seamless experience across devices and environments.
### **What You’ll Do**
- Design, build, and maintain a robust browser extension for Chrome, Edge, and other major browsers using Manifest V3 and modern APIs.
- Implement features that securely interact with web content and backend services, ensuring compliance with security best practices.
- Optimize performance and reliability across diverse environments and user workflows.
- Work closely with the endpoint agent and backend teams to ensure tight integration and consistent functionality across endpoints and services.
- Stay ahead of evolving browser APIs, security standards, and extension ecosystem changes.
- Participate in code reviews, testing, and continuous improvement of development processes.
### **Who You Are**
- You have extensive experience in software engineering: coding, testing, debugging, and automating complex TypeScript/JavasScript applications
- You're comfortable digging into third-party web applications you don't control — inspecting network traffic, DOM structure, and client-side code to understand how a page works
- You have the ability to learn new technologies quickly and are eager to do so — especially as browser extension platforms and manifest specs continue to evolve
- You focus on correctness, performance, and reliability of background processes
- You have excellent communication skills,
- You are able to work self-sufficiently at times with minimal direction.
- You can coordinate work effectively between yourself and developers working on non-browser platforms.
**Bonus points**
- You have hands-on experience building or maintaining browser extensions (Chrome/Chromium Manifest V3 experience strongly preferred; Firefox/Edge a plus), including background scripts, content scripts, and extension messaging patterns
- You understand the security model of browser extensions - permissions, content security policy, isolated worlds, and safe communication between contexts
- You have experience building cybersecurity products or features, such as DLP (Data Loss Prevention), DSPM (Data Security Posture Management), or similar security/compliance tooling
Joining Cyberhaven means joining the team building Data Security for the Agentic Enterprise. Traditional tools fall short. Cyberhaven traces the full lifecycle of your data, adapting protection to changing context, so protection moves with the way people actually work, not against it. AI Changed Work. We Protect It.
Backed by $250M from leading investors like Khosla and Redpoint, our team includes leaders who built industry-defining technologies at CrowdStrike, Palo Alto Networks, Meta, Google, and more. This role lets you shape the future of data security, working alongside people driven to protect workflows, not just data, for customers who cannot afford to slow down to stay safe.
**AI Tools Disclosure:** As part of Cyberhaven's hiring process, we use recruiting tools that include AI-powered features to help with tasks like scheduling, note-taking, workflow automation, and other recruiting activities ("AI Tools").
