リアル産業のオペレーションを再設計する｜AI Nativeな産業ソフトウェア開発

Description
なぜ、リアル産業の生産性は上がらないのか？

AIが急速に進化する一方で、多くの産業では依然として人に依存した業務プロセスが残っています。

設計・製造・調達・施工

建設業は、それぞれが異なる会社、異なるシステム、異なる担当者によって運用されており、多くの情報が分断されています。

BALLASが取り組んでいるのは、この分断されたオペレーションそのものをソフトウェアで再設計することです。

私たちは建設部材の調達プラットフォームを運営しながら一次情報を蓄積し、AI Nativeな産業インフラの構築に挑戦しています。

具体的な業務

AI Nativeな産業ソフトウェアの企画・設計・開発を担当いただきます。

• Vertical SaaSの設計・開発
• AI機能を組み込んだプロダクト開発
• フロントエンド・バックエンド横断での機能実装
• 顧客ヒアリングを踏まえた要件整理
• 業務オペレーションのモデリング
• API・DB・アーキテクチャ設計
• プロダクト品質向上のための継続改善

技術環境（2026年6月時点）

フロントエンド

React、Next.js、TypeScript

バックエンド

Python、FastAPI、NestJS、TypeScript、GraphQL、GraphQL

Testing

Jest

AI/ML

Vertex AI、Gemini、Cloud Vision API

Infrastructure

Google Cloud Platform (GCP)、Firebase、Vertex AI、Cloud Vision API、Gemini、Docker、Terraform、PostgreSQL

DevOps

GitHub、Notion、Cursor Agent、Devin、Gemini、Google Cloud Monitoring、Sentry、Google Cloud Monitoring

Design / Collaboration

Figma、Miro、Slack、Notion

このポジションで得られる挑戦

• AI Nativeな産業ソフトウェアの開発経験
• 顧客課題から要件定義まで一気通貫で関われる
• ソフトウェアだけでなく業務オペレーション設計に踏み込める
• リアル産業の複雑な課題をプロダクトで解決できる
• プロダクト・Biz・AIエンジニアと密に連携できる
• 0→1、1→10双方の経験を積める

なぜ、AIだけでは産業は変わらないのか？

多くのAIプロダクトは、既存業務の一部を効率化することに留まっています。

しかし、建設業や製造業のようなリアル産業では、単純な自動化だけでは価値を生み出せません。

そこには

・図面

・仕様書

・見積

・発注

・施工計画

といった膨大な非構造データが存在し、

さらに、

・企業ごとに異なる業務プロセス

・例外だらけの現場判断

・暗黙知に依存した意思決定

が複雑に絡み合っています。

AIが本当に価値を発揮するためには、業務そのものを構造化し、

AIが理解・実行できる状態へ変換する必要があります。

BALLASが取り組んでいるのは、単なるAI活用ではありません。

産業の意思決定をコード化し、再現可能な仕組みとして実装することです。

BALLASとは？

「建設業を最適化し、人々を幸せに。」をミッションに掲げ、建設サプライチェーンをアップグレードするテックカンパニーです。

プラットフォーム運営を通じて設計・調達・製造に携わりながら一次情報を蓄積し、業界の標準化・最適化を推進しています。

リアルなオペレーションをコード化し、AI Nativeな産業インフラの構築を目指しています。

BALLASのプロダクト

BALLASでは「BALLAS SCM」と「BALLAS LINKS」の2つのプロダクトがあります。

・「BALLAS SCM」：自社とパートナー工場様が使うサービスで、設計から製造までのオペレーションをAI Nativeに再設計するためのプロダクトです。

・「BALLAS LINKS」：お客様である建設工事会社様が使うプロダクトです。こちらは、建設工事会社様の内部にある設計・調達プロセスを統合するプロジェクト基盤になります。

今までお客様は、図面の管理にファイルサーバーやクラウド、仕様の協議はメールやチャット、やりとりは口頭と様々なツールを使い分ける状況でした。それを一つに統合することで、認識のズレや余計な工数を大幅に削減できます。さらに、蓄積された作図・購買プロセスデータをもとに、AIによる業務の自動化も進めています。

代表・木村の起業への想い

なぜBALLASを立ち上げたのか

1400年以上にわたり日本の発展を支えてきた建設業界は、今なお社会インフラを支える巨大産業です。一方で、現場では深刻な職人不足や、アナログで不透明な調達プロセスによる過度な調整負担など、産業全体の生産性を阻害する課題が残されています。

多重請負構造の中で分断されてきた設計・調達・製造・施工のプロセスをデータでつなぎ直し、人とAIが協働できる業務構造へ再設計することで、人が創造的な仕事や本質的な意思決定に集中できる産業を実現したい。

その想いから、BALLASを創業しました。

BALLASが目指すのは、
顧客・パートナーにDXを強制しないDX
です。

建設部材の調達プラットフォーム「BALLAS」は、自らがサプライヤーとして設計・調達・製造に携わりながら一次情報を蓄積し、業界の標準化・最適化を推進しています。「BALLASに頼めば、やり方を変えずに業務が最適化されていく」そんな体験を提供していきたいと考えています。
