Security Architect

Digital Assets Security Architect – Contract

Canada | Immediate Start

Are you a Security Architect with an interest in digital assets, cryptocurrency and blockchain technology, looking to work on some of the more complex security challenges emerging across financial services?

My client is an established global financial technology organisation investing heavily in digital assets, tokenisation and blockchain infrastructure. They are looking to bring in experienced Security Architects on an initial 3–6 month contract to provide specialist expertise across a growing portfolio of initiatives.

This is an opportunity to work directly with senior security leadership, assessing the architecture and security of emerging digital asset solutions, helping identify vulnerabilities and ensuring appropriate controls are embedded from the outset.

The role will involve:

• Reviewing the security architecture of digital asset initiatives, including wallets, custody, tokenisation, cryptocurrency and blockchain platforms.
• Assessing complex technology designs, identifying security gaps and recommending architectural and control improvements.
• Evaluating cryptographic security, key management, wallet infrastructure and custody models.
• Reviewing blockchain integrations, smart contracts and associated technology environments.
• Overseeing specialist third-party security assessments, including code audits, penetration testing and remediation.
• Advising engineering, product and senior security stakeholders on security requirements, risks and best practice.

They're looking for someone with:

• Strong experience in Security Architecture, ideally within financial services or another complex technology environment.
• A strong technical understanding of security design, architecture reviews and security controls.
• Experience with cryptography, encryption, key management and secure system design.
• Exposure to cryptocurrency, blockchain, Ethereum, digital assets, wallets or custody would be highly advantageous.
• The ability to independently assess complex systems, challenge existing designs and communicate security risks to senior stakeholders.

This is an opportunity to work at the intersection of financial services and digital assets, supporting the security of emerging technologies and helping shape the architecture and controls behind their development.

The initial engagement is expected to run for 3–6 months, with multiple contractors being considered. Rates are flexible depending on experience, and the organisation is looking to move quickly.

If you have a strong Security Architecture background and would be interested in exploring the opportunity, I'd welcome a confidential conversation.
