As a senior member of the UI team, you will play a critical role in architecting frontend solutions, mentoring peers, and contributing to the overall UI strategy. You will work closely with cross-functional teams to deliver intuitive, responsive, and secure interfaces that meet the demands of enterprise cybersecurity customers. Responsibilities: Lead the development of modular, high-quality UI components using JavaScript, TypeScript, and Angular. Translate product requirements and complex workflows into intuitive, performant user experiences. Collaborate with product, UX, and backend teams to define technical specs and architectural direction. Establish and enforce frontend coding standards, design patterns, and testing best practices. Own the performance optimization of large-scale UIs, proactively resolving rendering, loading, and responsiveness issues. Contribute to CI/CD pipelines, UI testing automation, and build/release tooling. Provide technical leadership and mentorship to junior developers through code reviews, design sessions, and paired programming. Actively participate in sprint planning, architecture reviews, and roadmap discussions. Investigate and resolve production issues with a focus on root cause and long-term stability. Bachelor’s/Master’s degree in Computer Science or a related field. 7+ years of professional experience building complex UI applications. Expert-level knowledge of JavaScript, TypeScript, and a modern UI framework (Angular preferred). Proven experience with large-scale enterprise UIs, reusable design systems, and performance optimization. Hands-on experience with unit testing, integration testing, and UI automation tools.
