AI Full-Stack Engineer / Founding Engineer

AI Full-Stack Engineer / Founding Engineer Base Salary: $100,000 – $140,000 Location: Hangzhou / Silicon Valley / Remote (Flexible) Industry: AI-Powered Products About the Role We're not hiring someone to just execute tasks. We're looking for a Founding-level AI Full-Stack Engineer who can think like a co-founder — define the product, architect solutions, build fast, and ship impactful features from day one. You'll work directly with the founder to shape an AI-native product from the ground up, blending strong full-stack engineering with deep AI integration. What You'll Do • Own core web and app features end-to-end — from ideation to deployment and rapid iteration. • Design and build scalable full-stack architecture, including APIs, databases, and modern frontend systems. • Integrate advanced AI capabilities such as LLMs, RAG, AI agents, and intelligent workflows. • Leverage AI tools aggressively to supercharge your own development speed and quality. • Think from the user's perspective, prioritize ruthlessly, and help evolve the product vision. What We're Looking For • Strong full-stack engineering skills with the ability to independently own features from start to finish. • Proficiency in React / Next.js (or equivalent modern frontend frameworks). • Solid experience with at least one backend stack: Python, Node.js, or Go. • Real hands-on experience building AI-powered products — not just calling OpenAI APIs. • Excellent product sense and the ability to balance technical excellence with user impact. • A builder mindset who thrives in ambiguity and moves quickly. Nice to Have • 0→1 startup experience or history of shipping independent products. • Background with consumer or subscription-based applications. • A strong public GitHub portfolio showcasing meaningful projects. • Fluent English for smooth collaboration. Compensation & Benefits • Base Salary: $100,000 – $140,000 USD (depending on experience and location) • Equity: Significant equity for founding team members • Flexible remote or hybrid options (Hangzhou, Silicon Valley, or fully remote) If you're a high-agency engineer who loves building AI products from scratch, iterating rapidly, and wearing multiple hats, this is an exciting opportunity to join early and have massive ownership.
