What You'll Do

As a founding frontend/full‑stack engineer at Peppr AI, you'll own features end‑to‑end—from UI/UX design through implementation—creating the interfaces that make our agentic AI platform intuitive and powerful for enterprise users.

You'll work with React, shadcn, react‑router, and FastAPI to build polished experiences that seamlessly integrate with our AI backend systems.

Key Responsibilities

• Design and ship polished interfaces with React, shadcn, and react‑router
• Take ownership of full features: mockup → implementation → QA → deployment
• Collaborate closely with product & design teams to craft delightful user experiences
• Build reusable, scalable frontend architecture and consistent design systems
• Optionally tie in backend work using FastAPI and PostgreSQL to deliver complete solutions

What We're Looking For

• 3+ years shipping production React applications with strong TypeScript/JavaScript skills
• Experience with UI libraries/components (shadcn or similar frameworks)
• Familiarity with react‑router, state management, form handling, and responsive design
• Basic design sense—experience in Figma, design systems, or styling frameworks
• Bonus: Experience building UI for AI‑driven workflows or agent interfaces

Nice-to-Have

• Backend experience with FastAPI or Python for full‑stack development
• Production experience with Docker, CI/CD, and some AWS or Kubernetes basics
• A product mindset and experience shipping end‑to‑end features
• Comfort with ambiguity and rapid iteration in a startup environment

This role offers the opportunity to shape both our user experience and technical architecture while building interfaces for the future of enterprise AI.
