We are partnering with Fortune 500 companies on a mission to transform the cybersecurity landscape with cutting-edge AI, including AI agents and Generative AI.


Why This Role Matters

By transforming technical requirements into fast, responsive, and intuitive interfaces, the UI Developer ensures that users experience clarity, speed, and reliability.

  • Contribute to code reviews, best practices, and technical documentation.


What We’re Looking For

  • 3–10 years of professional experience in UI/front-end development.
  • Strong proficiency in React, TypeScript, Next.js (good to have), and GraphQL (good to know, not a must)
  • Demonstrated experience building responsive and adaptive UIs.
  • Solid understanding of JavaScript (ES6 ), HTML5, and CSS3.
  • Experience with state management libraries (Redux, Apollo, or equivalent).
  • Strong debugging, performance optimization, and problem-solving skills.
  • Familiarity with Git, CI/CD workflows, and Agile development practices.
  • Bonus: Experience with server-side rendering (SSR) and static site generation (SSG) in Next.js.
  • Bonus: Strong eye for design and usability with experience collaborating in tools like Figma.
  • Bonus: Exposure to cloud platforms (AWS, Azure, or GCP) and DevOps pipelines.


Why Join Us?

  • Early-stage impact with the stability of $25M in seed funding
  • World-class leadership across AI, Engineering, and Product
  • Traction with Fortune 500s already in motion
  • Highly competitive comp & equity
