• Establish secure communication patterns among browser extension components, web applications, backend services, and native integrations.
• Guide decisions involving extension lifecycle, background services, content scripts, messaging, storage, and browser APIs.
• Address performance, memory, reliability, and scalability challenges across browser environments.
• Lead migration and modernization initiatives as browser extension standards and platform capabilities evolve.
• Partner with Product and UX to translate requirements into scalable technical designs.
• Collaborate with Security on threat modeling, secure design, and remediation of security-sensitive browser functionality.
• Lead architecture and design reviews and establish technical standards across the Browser Extension engineering team.
• Mentor senior engineers and improve engineering quality, architecture discipline, and technical decision-making.
• Collaborate with Vault, Desktop, Mobile, and backend teams on overlapping functionality and architecture.
• Use AI-assisted tools for architecture research, prototyping, debugging, code analysis, documentation, and engineering efficiency.

Requirements

• 10+ years of professional software engineering experience with full-stack expertise across databases, backend services, APIs, infrastructure, and modern user interfaces.
• Demonstrated 0-to-1 architecture experience delivering complex software systems from concept through production.
• Strong knowledge of software architecture, object-oriented design, and Gang of Four design patterns.
• Deep performance-engineering experience, including profiling, load testing, bottleneck analysis, and real-time debugging across the application stack.
• Experience designing highly available and scalable systems and evaluating centralized versus decentralized architectures.
• Strong understanding of distributed systems, microservices, serverless architectures, and event-driven application design.
• Experience with AWS, Lambda, Docker, and Kubernetes.
• Strong understanding of database architecture and data modeling across transactional, sharded or horizontally scaled, and analytical or warehouse systems.
• Experience designing authentication, authorization, and identity architectures involving IAM, CIEM, and least-privilege access.
• Strong knowledge of web and application security concepts, including CORS, OWASP guidance, and secure software development practices.
• Experience with static analysis, code quality, or application security tools such as SonarQube or Checkmarx.
• Strong understanding of software development methodologies, CI/CD practices, automated testing, and release engineering.
• Ability to make architectural tradeoffs across performance, security, scalability, reliability, maintainability, and delivery speed.
• Ability to troubleshoot issues across database, backend, infrastructure, network, and UI layers.
• Ability to lead architecture discussions, influence technical direction, and mentor senior engineers without formal people-management authority.
• Ability and willingness to use AI-assisted tools such as Claude, ChatGPT, and GitHub Copilot.
• Bachelor’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience.
• Preferred qualifications include deep browser-extension or client-platform experience, enterprise security-platform experience, familiarity with high-scale SaaS and zero-trust architectures, compliance-framework knowledge, accessibility familiarity, product analytics experience, data-platform familiarity, AI or machine-learning workflow experience, and native application or endpoint integration experience.
