Building an Engineer Paradise
in Japan
Bridging Silicon Valley's exponential innovation with Japanese enterprise. We're building beautiful data infrastructure and LLM agent platforms — and looking for engineers to join us.
Why — Exponential vs Linear
AI and dev-tool innovation in Silicon Valley is growing exponentially. Japanese enterprise is still changing linearly. Bridging this gap is why INDX exists.
Exponential Growth
LLMs, AI agents, new dev tools… Past the inflection point and accelerating.
Linear Change
Massive domain data, solid business foundations. But slow to adopt tech innovation. A massive opportunity.
INDX is the bridge that beautifully connects these two worlds.
What We Do — INDX Solutions
We transform massive unstructured enterprise data into AI-ready formats and deliver industry-specific AI solutions.
Unstructured Data
Business Value
Data Structuring Engine — 4 Steps
Parse & Chunk
Layout analysis, semantic tagging, text segmentation
Decompose & Vectorize
Structure decomposition, tagging, indexing
Extract & Recognize
Graph/table extraction, entity identification
Metadata Extraction & Analysis
Automated metadata extraction and structured data analysis
How — Master · Deliver · Sustain
To truly thrive as an engineer, you need three things: technology worth mastering, real problems to solve with it, and a stable foundation to keep doing it.
Master Your Craft
An environment where you can dive deep into the technology you want to master. Rust, GenAI, LLM agents — rapid experimentation with our CTO Cluzeau's R&D team, balanced with solid product development.
Deliver Real Impact
Your code directly becomes customer value. Engineering output is directly proportional to business impact — you'll feel your technology making a real difference in the world.
Grow Sustainably
Not a temporary boom — a place to grow perpetually as an engineer. Enterprise moats and carefully built partnerships create a stable revenue foundation.
Tech Creates Value, Value Accelerates Tech
Engineering excellence directly drives customer value, and that growth enables even more tech investment — INDX keeps this flywheel spinning.
Every turn of this cycle expands engineer autonomy, tech investment, and customer value. That's what makes INDX an "Engineer Paradise."
What You'll Work On
From domain-specific data curation to AI agent development and building reproducible products.
Domain-Specific Data Infrastructure
Build enterprise data agents, develop data structuring engines, and create data applications. End-to-end ownership from development through PoC validation.
AI Agent Development
Design and build AI agents that deliver real value. Leverage cutting-edge LLM capabilities to build enterprise-grade agents.
Product Development
Deliver products customers love — fast and precise. Build reproducible, domain-specific products that delight users.
R&D & Tech Exploration
Explore the frontier with CTO Cluzeau (10+ years engineering, 4+ years as CTO) and the R&D team. Push the limits of Rust, GenAI infrastructure, and more through rapid experimentation.
Tech Stack
Aggressively adopting the latest. Building with an ambitious stack.
Messages from Leadership
We want to build "beautiful data infrastructure" and "beautiful LLM agent platforms" that bridge Silicon Valley's exponential innovation with Japanese enterprise's linear evolution. An environment where engineers master technology, deliver value to society, and sustain it forever — that's our vision of "Engineer Paradise."
At INDX, engineers work on genuinely exciting technical challenges. We implement cutting-edge AI at enterprise quality, balancing R&D exploration with solid product development. Join us in building a team that never compromises on technology. We're looking for engineers who want to push the limits with us.
