This is a hands-on role focused on end-to-end delivery, turning complex AI systems into working, scalable tools that people use every day.The Role:
As a senior member of a product-focused AI team, you’ll work closely with engineers and product leads to build LLM-powered applications that solve meaningful problems.
You’ll design intelligent agent workflows, experiment with multimodal inputs, and deploy production-ready AI systems from scratch. This is the ideal role for someone who’s already been through the journey of taking generative AI beyond a prototype and into the hands of real users.
What You’ll Be Doing:
Designing and building AI-powered systems, including multi-agent workflows and conversational tools.
Creating production-level Python code using modern engineering best practices (CI/CD, Terraform, containerisation).
Developing RAG systems, fine-tuning models, and optimising prompts for complex use cases.
Collaborating closely with product teams to translate ideas into shipped features.
Working with multimodal inputs (text, audio, video) to deliver innovative AI experiences.
Playing a key role in building out a new Tokyo-based team, as part of a long-term global strategy to scale AI innovation from Japan.
What You’ll Need to Succeed:
7+ years of professional software engineering experience.
Strong Python skills and experience shipping production-ready code.
Hands-on work with modern generative AI models (LLMs, multimodal).
Deep experience in prompt engineering, RAG, and model fine-tuning.
Track record of building and launching AI systems used by real users.
Familiarity with infrastructure as code, cloud environments, and scalable systems.
Comfortable in a fast-paced, collaborative team.
Willingness to relocate to Tokyo (visa sponsorship provided).
Bonus If You Bring:
Experience with LangChain, Pinecone, Hugging Face, or similar tools.
Background in multimodal AI or advanced computer vision.
Understanding of MLOps/LLMOps principles and vector databases.
Prior experience building AI systems in a consumer product environment.
What’s in It for You:
A global, product-focused role with high visibility and impact.
Competitive salary, visa sponsorship and relocation support to join the Tokyo team.
Work on novel AI applications with an ambitious team.
Be part of a mission-driven company using technology to improve everyday life at scale.
