Job description

Responsibilities

• Own product features end to end across the web frontend, mobile apps, and business backend services, from understanding requirements and designing solutions to rollout and production maintenance.

• Independently judge whether a technical approach will work, take responsibility for your own code and delivery quality, and proactively discuss with colleagues when you are unsure about an approach.

• Work closely with product, design, and other engineers to understand business and user needs and deliver features with high quality.

• Drive projects in an AI-native way: proactively use AI tools to improve development, testing, troubleshooting, and documentation workflows, and help bring Agent and LLM capabilities into the product.

• Continuously improve code quality, performance, stability, and observability, and track down and fix production issues.

Requirements

• Several years of deep, hands-on experience in at least one of web frontend, mobile (iOS / Android), or business backend development, with a solid grasp of the key implementation details and technical trade-offs in that area.

• Ability to extend into other parts of the stack and deliver complete cross-stack features independently; candidates who have focused on one area so far and want to grow into full-stack work are also welcome.

• Experience building user-facing products at a large internet company, or at an AI or internet startup.

• Ability to judge the feasibility of technical approaches independently, without relying on others' code reviews as a safety net, and to take responsibility for delivery quality and outcomes.

• Ability to break down and drive projects in an AI-native way, making good use of AI tools to improve development efficiency, delivery quality, and collaboration.

• Ability to collaborate on technical work in Mandarin and to read, write and participate in day-to-day technical communication in English.

• Strong communication skills and a sense of ownership, with the initiative to drive work forward and a desire to keep writing code hands-on.
