About the role


Position: Senior Full Stack Python Developer


Here's how client business works in simple terms:

 

Buying Mortgages: Fannie Mae buys home loans from banks and other lenders. This gives those lenders more money to make new loans to other people.

Guaranteeing Loans: Fannie Mae guarantees these loans, which means if a borrower can't pay back the loan, Fannie Mae will cover it. This reduces the risk for lenders.

Creating Mortgage-Backed Securities: Fannie Mae bundles these loans into mortgage-backed securities (MBS) and sells them to investors. This process helps to keep the mortgage market stable and ensures there's always money available for new home loans.

By doing all this, Fannie Mae helps more people get mortgages, which supports the housing market and makes it easier for people to buy homes.
