About the Role

As AI profoundly transforms how engineering teams work, we are looking for Full Stack Engineers to serve as "seeds" across our product teams. You will be among the first dedicated full stack engineers, helping the organization establish a highly autonomous, AI-augmented, end-to-end development model.

Responsibilities

• Participate in end-to-end development of product features across frontend and backend under the guidance of senior engineers
• Learn and integrate mainstream AI coding tools (e.g., Cursor, Copilot, Claude Code) into your daily development workflow
• Assist in translating product requirements into working implementations with reduced handoff friction between frontend and backend
• Act as a full stack "seed learner" within the team — absorb full stack practices, contribute ideas, and grow into an autonomously delivering full stack engineer
• Observe cross-team collaboration processes and proactively suggest improvements to product, design, and engineering workflows
• Contribute to the product lifecycle — from design to deployment and iteration

Requirements

• Currently pursuing a Bachelor's degree or above; Computer Science or AI-related major is a plus
• Hands-on project experience (personal projects, coursework, internships, or open-source contributions all count)
• Foundation in at least one backend language: Java or Golang
• Familiarity with Node.js and modern frontend frameworks
• Experience building end-to-end projects — personal, academic, or internship projects all welcome
• Basic understanding of database design and core backend concepts
• Familiarity with mainstream AI coding tools (Cursor, Copilot, Claude Code, or similar)
• Ability to clearly articulate requirements and constraints to AI tools
• Self-driven and boundaryless — eager to learn, willing to go beyond assigned scope
• Product mindset — curious about the "why" behind what you build
• Strong logical thinking and communication skills; passionate about learning new technologies

Nice to Have

• Open-source contributions or notable GitHub projects
• Cross-platform development experience (iOS/Android/Web)
• Internship or work experience at startups
• Track record of proactively building internal tools or personal side projects
