Job description

We are seeking a Senior Frontend Engineer to join our core team. In this role, you'll take ownership of designing and building the user-facing components of our AI-native cloud platform. You'll architect scalable, high-performance web interfaces that make complex cybersecurity capabilities intuitive and accessible.
As our systems become increasingly AI-driven, a key part of your work will be building interfaces that make these intelligent systems explainable and trustworthy. You'll help users understand how AI decisions are made - turning model outputs and security insights into clear, actionable, and transparent experiences.
As a senior member of the team, you'll shape our frontend architecture, mentor other engineers, and collaborate closely with design and product to deliver exceptional, insight-driven user experiences.
Responsibilities
  • Architect and implement sophisticated, performant web interfaces for our AI-native cloud platform.
  • Drive frontend technical direction, selecting modern frameworks, libraries, and tools to ensure scalability, maintainability, and performance.
  • Collaborate closely with product, design, and backend teams to translate complex cybersecurity use cases into intuitive, user-centered experiences.
  • Define and uphold best practices in coding standards, testing, and frontend architecture.
  • Optimize performance across browsers and devices, ensuring accessibility and responsiveness.
  • Contribute to long-term engineering strategy.
  • Provide expert technical feedback on UX designs and feature requirements.
Requirements
  • 7+ years of professional frontend engineering experience, with a proven track record of building and scaling production-grade web applications.
  • Deep expertise in React (or similar modern frameworks such as Vue or Angular) and strong proficiency in JavaScript and TypeScript.
  • Strong experience with frontend architecture, APIs and performance optimization.
  • Familiarity with cloud-based environments and integration with backend APIs and services.
  • Comfortable working with AI Coding tools such as Cursor.
  • Demonstrated experience with UI/UX best practices, responsive design, and accessibility standards.
  • Ability to make sound technical decisions in a rapidly-changing environment and communicate trade-offs effectively.
  • Bachelor's degree in Computer Science or a related field (or equivalent practical experience).
  • A collaborative, proactive mindset with excellent problem-solving and communication skills.
