We’re looking for a Senior LLMOps Engineer to join an R&D team of an ambitious deep-tech startup with a ~30-person international team and HQ in Tokyo
The Project
The team is building a natively agentic graph-neuro-symbolic AI system with general capabilities — not just another LLM product, but a foundational AI architecture.
The system combines:
- principles from mathematical category theory;
- knowledge representation;
- computational linguistics.
The focus is on interpretable, controllable, and safe intelligence, enabling powerful reasoning without turning AI into a black box. This is deep, research-driven work with real production impact.

Responsibilities
- Design, build, and maintain production-grade LLM systems;
- Own the full LLMOps lifecycle: data preparation, fine-tuning, evaluation, deployment, monitoring, and iteration;
- Build evaluation frameworks to track quality, robustness, and regressions;
- Work closely with researchers and engineers to productionize research prototypes;
- Contribute to architecture decisions for agentic systems, RAG pipelines, and hybrid ML + symbolic solutions.
What We’re Looking For
- 5+ years of experience in ML / Applied AI;
- Hands-on experience deploying ML or LLM systems into production;
- Practical experience with LLMs (open-source or proprietary) in real use cases;
- Strong understanding of modern LLM stacks: fine-tuning, inference optimization, RAG, agents;
- Experience with MLOps / LLMOps tooling (evaluation, monitoring, CI/CD for models);
- Strong Python skills; familiarity with ML frameworks;
- Experience with Docker, Kubernetes (or equivalents) and GPU environments;
- Startup or R&D-heavy background is a strong plus;
- Fluent conversational English — you’ll work daily in an international team.
What’s Offered
- 16–22M JPY gross per year (~$105k–145k gross);
- High autonomy, low bureaucracy, real ownership;
- English & Japanese language learning support;
- Full Japanese social security + additional medical coverage;
- Up to 25 paid vacation days per year.
