Everyone is encouraged to work together to accomplish a common goal.


Vice President, IT Program Management

My time at Pennymac has rocketed my career as a software dev. In two years I went from having no professional coding background to managing three applications in production, managing two direct staff and contributing to open-source libraries. My time has given me the experience and skills to successfully create new tech products that make money.


Assistant Vice President, Application Development

How do your team's ideas influence the company's direction?

As a company, we're one very cohesive, supportive team with various areas of expertise. It's like a potluck - everyone brings something different, but it all comes together perfectly. Company management believes in us, trusts us, and invests in us. That provides the opportunity to build positive outcomes for our business and our customers.
