- Own architectural direction across backend services, AI pipelines, infrastructure, and data layers
- Lead technical roadmap planning, technology evaluation, and proof-of-concept development
- Provide hands-on leadership through design reviews, architecture reviews, and code reviews
- Mentor and develop engineers, raising engineering quality, productivity, and technical rigor
- Collaborate closely with Product, Design, AI/ML, and global engineering teams to ensure cohesive delivery, and represent the Korea engineering team in cross-regional technical discussions and initiatives

- Bachelor's degree in Computer Science, AI, Machine Learning, or equivalent practical experience
- 5+ years of professional software engineering experience using modern technology stacks, such as Python, .NET, Java, React, TypeScript, cloud platforms (e.g. AWS), relational and vector databases, and version control/CI/CD pipelines
- 3+ years of hands-on experience building AI/ML systems, including LLM integration (e.g. GPT, Claude, Gemini), RAG system design, optimisation and evaluation, vector search and semantic retrieval, and prompt engineering and LLM orchestration frameworks
- 3+ years of experience leading projects or teams in a technical leadership capacity
- Experience designing, deploying, and operating secure, production-grade web systems
- Strong understanding of DevOps practices and CI/CD pipeline design
- Fluency in Korean and English, both written and spoken
