Software Engineer, Securities Finance

As a Software Engineer on the Securities Finance (SecFi) team, you'll build and run the systems behind Alpaca's lending and borrowing products. The work is backend, and it matters given the scope of powering various brokerage customer experiences

The two current customer-facing products are Fully Paid Securities Lending (FPSL), where we lend out customers' fully paid shares and split the revenue back with them, and customer short borrowing, where we source hard-to-borrow locates. Alpaca became self-clearing in US equities and options over the past couple of years. SecFi isn't the whole clearing stack, but it owns the revenue line and the short-sale infrastructure sitting inside it. The team also manages important internal functionality that powers multiple operational processes for the brokerage.
