Tech Stack Proficiency
Strong command of TypeScript.
Hands-on experience with modern JavaScript frameworks such as React or Angular.
Solid understanding of API integration (REST) and consuming backend services.
Experience with front-end testing frameworks, including Playwright (end-to-end testing), Cypress (end-to-end and integration testing), Jest (unit and integration testing), and Testing Library (React Testing Library, Angular Testing Library, etc. for component testing).
Experience using Figma for UI/UX design interpretation and implementation.


Who You Are
A builder: You go from problem to prototype to production, closing gaps and creating real experiences.
Craft-obsessed: You hold high standards for clean, performant, accessible UI- even when shipping quickly.
Intuition-driven: You make smart architecture decisions, evaluate tradeoffs, and move forward even with ambiguous requirements.
GenAI-minded: You approach UI design and development from the perspective of GenAI applications, understanding how to create interfaces that best enable and represent GenAI functionality.
Frontend-first with full-stack awareness: React is your primary tool, with strong Angular capabilities.
You understand how frontend connects to backend services.
Outcome-focused: You build around the user's real experience, with every component and interaction considered.

Ability to architect, debug, and ship high-quality UI solutions.
Strong communication skills-you can align engineers, designers, and stakeholders around a technical approach.
Experience using Figma for UI/UX design interpretation and implementation.


Plus Skills
Experience with Python for backend development or AI integration.
GenAI skills: familiarity with GenAI APIs, prompt engineering, or building GenAI powered UI features.
Experience building and scaling design systems or shared component libraries.
Deep knowledge of frontend performance optimization, accessibility (WCAG), and responsive design.
Experience with modern build tools, CI/CD pipelines, and frontend testing frameworks (Jest, Cypress, Playwright, Testing Library).
Excellent product instincts-partnering with product and design to shape what gets built, not just how.
Ability to take a loosely defined business problem and drive it to a well-scoped technical solution.
Track record of raising the bar for frontend engineering quality across a team (testing practices, observability, code review standards).
Experience with AWS or similar cloud platforms for frontend hosting and delivery (CloudFront, S3, etc.).
Security engineering experience.
