Principal Security Architect (On-Chain security & Custody)

Info Security Full-time About BTSE: BTSE Group is a global leader in fintech and blockchain technology, anchored by three core business pillars: Exchange, Payments, and Infrastructure Development. Serving over 100 corporate clients worldwide, we provide white-label exchange and payment solutions. Our offerings encompass everything from exchange infrastructure hosting and development to custody, wallets, payments, blockchain integration, trading, and more. We are looking for talented professionals in marketing, operations, customer support, and other departments. The roles offered may be on-site, remote, or hybrid, in collaboration with our local partner. About the Opportunity: We are looking for a Principal Security Architect with deep crypto domain expertise to own security for the custody and on-chain layer of our regulated digital-asset platform end to end, spanning architecture, engineering, operations and regulatory assurance. Reporting into the central security function, you will define crypto-specific requirements and partner with dedicated InfraSec, AppSec, IAM and SOC teams on the platform capabilities they already own, rather than duplicating those functions. You will work closely with risk, compliance, product and engineering as we build out spot trading, custody, staking and on-chain services. This is a hands-on senior role for someone who understands that in digital-asset custody a single key-management failure is a firm-ending event, and who builds controls accordingly.
