Department: Technology
Reporting To: SVP, Research & Engineering

TookiTaki is scaling rapidly across global financial institutions, with cloud infrastructure at the core of our product delivery, reliability, and regulatory posture. As we scale, cloud efficiency, cost discipline, and architectural rigor become as critical as uptime and security.

The Head of Cloud Infrastructure will not only own the design and reliability of TookiTakiʼs cloud platforms, but will also lead a fundamental shift in how cloud spend is planned, governed, optimized, and linked to business outcomes. This role is expected to balance performance, resilience, and compliance while materially improving cost efficiency, spend predictability, and infrastructure ROI. This is a senior leadership role with direct impact on operating margins, gross efficiency, and long‑term scalability of the business.
