Senior Frontend Engineer (React / Next.js)

ARQ (arq.live) is an AI video startup building next-generation tools for video generation — from short clips to production-level content — powered by our own models and multimodal pipelines. We’re moving fast, shipping constantly, and improving the product every week. This is a real startup environment: lots of ownership, fast iterations, and no enterprise-style comfort zone. We are looking for a strong frontend engineer who can take responsibility for key parts of the product and help push UX and performance to the next level.

• Remotion (video editor inside the app)
• Integration with LLM agents (LangGraph SDK)

Backend: FastAPI + LangGraph (Python), partially Go

What You’ll Do

• Build and improve the core UI of an AI video product
• Work on complex interactive editor flows (graphs, real-time updates)
• Push usability, polish, and advanced frontend logic
• Collaborate closely with backend and AI components of the system
• Communicate directly with the founders on product decisions and priorities

What We’re Looking For

• Strong frontend engineer with solid React/Next.js experience
• Comfortable working in a fast-moving startup setup
• Able to take ownership and move quickly without heavy processes
• Product mindset and attention to UX details
