The KL R&D Center is our core overseas engineering hub, responsible for building and iterating our product and technology stack locally. We are looking for a Senior Backend Engineer / Tech Lead to join and help lead the KL engineering team. This role combines hands-on technical leadership with team management, serving as the technical backbone of the local R&D center. You will drive architecture decisions, own the technical roadmap for key systems, and mentor a growing engineering team — while still writing and reviewing production code daily.

Responsibilities

Technical Leadership

• Lead the architecture design and technical decision-making for intelligent conversational robot systems and AI SaaS platforms.
• Own the technical roadmap: evaluate trade-offs, drive technology selection, and ensure the system is scalable, reliable, and maintainable.
• Design and implement core backend services using Golang and Python, covering high-concurrency scenarios, distributed systems, and API architecture.
• Drive innovation projects based on LLM / large language models, exploring new product capabilities and engineering approaches.
• Establish and enforce engineering best practices: code review standards, CI/CD pipelines, testing strategies, monitoring and alerting.

Team Management

• Manage and grow the local backend engineering team: task planning, sprint coordination, performance feedback, and hiring.
• Mentor junior and mid-level engineers, fostering a culture of technical excellence and continuous learning.
• Serve as the communication bridge between KL R&D center and headquarters (Shanghai), ensuring alignment on priorities, progress, and technical direction.

Qualifications

Required

• Bachelor's degree or higher in Computer Science or a related field.
• 5+ years of backend development experience, with 3+ years using Golang in production environments.
• Strong system design and architecture skills; proven experience leading the design of complex distributed systems.
• Deep understanding of Linux, network protocols (TCP/IP, HTTP/2, gRPC), and common middleware (Redis, Kafka/RabbitMQ, MySQL/PostgreSQL, MongoDB, etc.).
• 1+ years of team management or tech lead experience; comfortable with task allocation, code review ownership, and cross-team coordination.
• Proficiency in English — able to participate in technical discussions, write documentation, and communicate with both local and overseas teams. Added advantage if able to converse in Chinese as collaboration is expected with China-based teams.
• Strong logical thinking, ownership mentality, and the ability to independently drive projects from ambiguous requirements to production delivery.

Preferred

• Hands-on Python development experience; familiarity with Python ecosystem for AI/ML or scripting use cases.
• Experience with AI/LLM integration, prompt engineering, or building AI-powered product features.
• Experience developing or operating intelligent conversational robot / voice bot systems.
• Experience working in cross-cultural, distributed teams (especially China + Southeast Asia collaboration). 。
• Familiarity with cloud platforms (AWS / GCP / Alibaba Cloud) and containerized deployment (Docker, Kubernetes).

What We Offer

• Core role in building a high-impact R&D center from the ground up in Southeast Asia.
• Direct involvement in cutting-edge AI + LLM product innovation.
• Competitive compensation package with growth potential as the team scales.
• Collaborative environment bridging China and Southeast Asia engineering cultures.
