• Translate product and design specifications into elegant, usable interfaces, collaborating closely with backend engineers and designers to deliver secure flows.

• Establish scalable frontend architecture and internal component libraries, with an emphasis on security (login, authentication, form validation).

• Contribute to shaping the product experience from the ground up, with opportunities to define best practices and influence technical direction.

Qualifications

• Proficiency in React, TypeScript, and modern frontend tooling.

• Experience developing secure user flows (e.g., authentication, identity verification, form handling).

• Strong design intuition and attention to detail in UI/UX.

• Comfort working in fast-paced, ambiguous startup environments with ownership over full feature lifecycles.

• Preferred: familiarity with Tailwind, Next.js, Playwright, or testing frameworks; prior experience in identity, fintech, or other security-focused domains; experience building dashboards, SDKs, or B2B interfaces.
