A fast-growing Japan-based AI research and product company is building the next generation of personalized AGI and AI-native consumer products. Following a major funding round of approximately ¥10 billion in early 2026, the company is accelerating both advanced AI research and global consumer product development. The engineering organization is small, highly skilled, and focused on moving quickly from ideas to real products.
We are looking for an Applied AI Engineer to turn cutting-edge AI capabilities into products that users genuinely love. You will sit on the product side, working closely with platform and AI infrastructure teams. Rather than building models from scratch, you will combine existing AI capabilities with prompt engineering, frontend/UI development, rapid prototyping, experimentation, and LLM integrations to create and improve user-facing AI features.
Requirements:
7+ years of professional software development experience
Experience developing, launching, and operating user-facing products, particularly B2C products
Hands-on experience integrating LLMs / Generative AI into products
Experience with prompt design, testing, and optimization
Business level Japanese
Why Join?
Build at the cutting edge of AI: Work directly on products powered by the latest LLM and AI technologies.
High ownership: Your engineering, prompt, and product decisions can directly influence the user experience.
Move fast: Work in short prototype → experiment → learn cycles rather than long development cycles.
Small, high-caliber team: Collaborate with experienced engineers and AI researchers in a highly focused environment.
