Astemo Cypremos株式会社は、グローバル自動車メーカーの SDV（Software Defined Vehicle）対応や次世代モビリティの進化を支えるために設立されたスタートアップで、クラウドベースのデジタル開発環境（例：デジタルツイン）を軸に事業を成長させています。
FY25〜FY26にかけて、プロダクト開発・事業拡大・グローバル展開を進める中で、必要なケイパビリティを適時獲得しながら、社員が高いパフォーマンスを出し続けられる環境づくりを加速しています。

本ポジションは Head of People直下で、これまで整備してきた人事労務・People Operationsの基盤を引き継ぎ、急拡大する組織を支える「実装の中核」を担います。採用・オンボーディング・勤怠/給与社保・評価運用などの日々の実務を回しつつ、ツール活用（HirePlanner / Deel / Workday Shell / ジョブカン / Power Apps 等）と仕組み化で、他部門がコア業務に集中できる状態をつくります。

当社が目指すのは「世界中の優秀な人材が集まり、どこにいても当社のAmbitionに貢献できるチーム＆仕組み」です。そのために、Innovation / Agility / Integrity / D&I / Leadership / Collaboration を土台に、心理的安全性や円滑なコミュニケーションを支えるオペレーションとカルチャーづくりを重視しています。
少人数の人事チームだからこそ、国内外の多様なメンバーを支える実務（例：ビザ支援、海外在住メンバー対応）から、データドリブンな人事運用、福利厚生導入、ルール整備まで、幅広く深く挑戦できます。

Astemo Cypremos, Ltd. is a startup established to support global automakers’ SDV (Software Defined Vehicle) initiatives and the evolution of next-generation mobility, growing rapidly around cloud-based digital development environments (e.g., digital twins).
As we accelerate product development, business expansion, and global scaling in FY25–FY26, we are continuously acquiring the capabilities we need while building an environment where employees can sustain high performance.

Reporting directly to the Head of People, this role is the execution core of People Operations—taking over and strengthening the HR foundation already built. You will run end-to-end HR operations (recruiting, onboarding, time & attendance, payroll/social insurance, performance/OKR operations) and drive operational excellence through system enablement (HirePlanner / Deel / Workday Shell / Jobcan / Power Apps, etc.) so that teams can focus on their core work.

Our long-term HR ambition is to build a team and framework that attracts top global talent and enables meaningful contribution from anywhere. We emphasize a culture grounded in Innovation / Agility / Integrity / D&I / Leadership / Collaboration, psychological safety, and smooth communication.
Because our HR team is lean and the organization is scaling fast, you will gain unusually broad and deep exposure—from global mobility/visa support and supporting diverse remote members, to data-driven HR operations, benefits rollout, and policy implementation.
