Software Architect / System Architect

We are looking for an experienced Software / System Architect to design and review the architecture of a closed-loop financial platform.

The platform includes user accounts, balances, transactions, deposits/withdrawals, trading, payments, wallet functionality, and administration.

We already have a development team and an existing system. We need an architect who can review the current setup, identify gaps, design the overall system architecture and flows, and provide clear technical guidance and architecture documentation for our developers.

Experience with FinTech, payment systems, trading platforms, digital assets, banking, or other transaction-heavy financial systems is highly preferred.

Please share relevant architecture experience and examples of similar systems you have worked on.
