Head of Security
About The Position
We are partnering with Quant, a global leader in digital transformation and technology solutions, seeking an Head of Security to join their team. Securing a chain platform that moves regulated money is not the same problem as securing an enterprise, and the people who have done both are rare. We are hiring someone to own it. The role involves continuous detection and response, managing the certificate and PKI lifecycle, feeding threat intelligence into the platform's protective controls, and transaction monitoring and on-chain analytics. You will work alongside the reliability team during incidents, as most serious security events are also availability events. Much of the security model is being established rather than inherited, and you will be responsible for establishing it and proving it to those who find gaps. There is more to this role than can be put in an advertisement.
Requirements
- Led security operations in financial services or another regulated industry.
- Built or run a function with continuous coverage.
- Know the difference between an alert and a signal.
- PKI and certificate lifecycle ownership at scale.
- Produced evidence for a regulator.
- Ability to prove what you did and why you took the action that you did.
Nice To Haves
- Blockchain analytics and on-chain transaction monitoring.
- Operating inside a client’s security tooling rather than your own.
- Digital asset custody or exchange security.
Responsibilities
- Detection and response running continuously.
- Certificate and PKI lifecycle management.
- Threat intelligence feeding the platform's protective controls.
- Transaction monitoring and on-chain analytics.
- Working alongside the reliability team during incidents.
- Establishing and proving the security model.
