Senior Applied AI Engineer

Join a fast-paced AI team working across text, video, and multi-agent systems. As Senior Applied AI Engineer, you’ll design and deploy intelligent, user-facing products powered by large language models (LLMs). 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.
