You will work on user-facing interfaces, backend services, APIs, data integrations, and LLM-powered capabilities.

We are looking for someone who can move fast, learn quickly, and use AI tools effectively to deliver end-to-end product features.

This is not a pure frontend or pure backend role.

We value engineers who can take ownership of a feature from requirement understanding to UI implementation, backend logic, AI integration, testing, and iteration.

Responsibilities

• Build and maintain end-to-end product features across frontend, backend, and AI/LLM components.
• Develop user interfaces for internal tools, dashboards, AI assistants, automation workflows, and productivity platforms.
• Build backend services, APIs, data pipelines, task workflows, and integrations with internal or external systems.
• Integrate LLM/AI capabilities into real product scenarios, such as intelligent assistants, RAG workflows, AI agents, automation tools, classification, summarization, and issue analysis.
• Use AI coding tools to improve development speed, code quality, testing, and debugging.
• Work with product, operations, support, engineering, security, and infrastructure teams to understand user needs and deliver practical solutions.
• Participate in product iteration based on user feedback, usage data, and business impact.
• Write clean, maintainable code and contribute to documentation, testing, and engineering best practices.

Requirements

• Bachelor’s degree or above in Computer Science, Software Engineering, Engineering, or a related field.
• Solid programming foundation and ability to learn new technologies quickly.
• Hands-on experience with at least one frontend framework, such as React, Vue, Angular, or similar.
• Hands-on experience with at least one backend language or framework, such as Python, Go, Java, Node. js, Fast API, Spring Boot, Express, or similar.
• Basic understanding of frontend engineering, including component design, state management, API integration, UI debugging, and browser fundamentals.
• Basic understanding of backend engineering, including API design, databases, authentication, async jobs, logging, monitoring, and service reliability.

• Real experience with LLM/AI applications, such as

• LLM API integration
• Prompt engineering
• RAG
• AI agents
• Tool/function calling
• Workflow automation
• Text classification / summarization / extraction
• LLM output evaluation
• Comfortable using AI coding tools such as Cursor, Claude Code, Git Hub Copilot, Cline, Open Code, or similar tools in daily development.
• Strong ownership, good communication skills, and willingness to work on ambiguous problems.
• Ability to deliver practical solutions with both engineering quality and user experience in mind.
• Nice to Have
• Experience building AI-powered products, internal tools, dashboards, workflow automation systems, or data-driven applications.
• Experience with LLM/Agent/RAG frameworks such as Lang Chain, Llama Index, Dify, Auto Gen, Crew AI, Open AI API, Anthropic API, Hugging Face, or similar.
• Experience with vector databases, embeddings, semantic search, knowledge bases, or retrieval systems.
• Experience with observability, monitoring, alerting, incident analysis, Dev Ops, SRE, or workflow automation.
• Experience with UI/UX design thinking or building usable internal tools from scratch.
• Experience using AI tools to build full-stack features faster, including frontend generation, backend scaffolding, tests, and documentation.
• Personal AI projects, hackathon projects, open-source contributions, or production AI application experience.
• Good technical writing and knowledge sharing habits.
