Description

About Unlimit

Unlimit is a global fintech ecosystem built to eliminate financial borders holding businesses back. The company provides the extensive infrastructure needed to scale globally, integrating payment processing, multi-currency business accounts, BaaS and crypto gateways into a single, intelligent platform.

Across 17 offices globally, Unlimit bridges hyper-local expertise with a high-capacity financial network, giving companies the agility to expand across regions with operational confidence and speed. Driving the evolution of payments, Unlimit is transforming its infrastructure from human-operated fintech into AI-native financial infrastructure — where APIs are consumed by machines, integrations are negotiated by agents, and systems evolve continuously through intelligent automation. Our next users are not only humans. They are AI agents acting on behalf of humans and businesses.

Unlimit serves more than the needs of businesses today; we are building the nervous system for a borderless global economy.

As we continue to expand across regulated markets worldwide, we’re looking for a Head of Cyber Security to lead our global Cyber Security function. Reporting directly to the CISO, you’ll drive the operational execution of Unlimit’s cyber security strategy, ensuring our infrastructure, applications, cloud platforms, and security operations remain resilient against an evolving threat landscape.

As Head of Cyber Security, you will lead the teams and technologies responsible for protecting Unlimit’s global technology ecosystem. Working alongside the CISO, Engineering, Infrastructure, Product, and Information Security teams, you’ll own operational cyber security, continuously improving our detection, response, engineering, and application security capabilities.

This is a hands-on technical leadership role for someone who enjoys building modern cyber defence capabilities through automation, AI, and engineering excellence. You’ll play a key role in transforming traditional security operations into intelligent, highly automated security platforms powered by agentic workflows.
