Senior Software Engineer

About JanuaryCollections runs like an emergency room. You show up in crisis, get triaged by a stranger who doesn't know your history and leave with no follow-up. We're turning it into primary care for consumer finance. We started in the hardest, most broken stage, because if it works there it works anywhere. 70 million Americans fall behind on a debt every year. Most want to pay what they owe and can't find a way back. We've serviced over $20 billion in debt across more than 20 million consumers. We see more people with charged-off loans each year than all but the top five US banks. They rate us about 50% higher than the banks that lent them the money. Creditors net over 30% more with us because we collect more and charge less. Most AI strips the human out of the work. We use it to do the opposite. In someone's hardest financial moment we make the experience more human. The more human we make it, the more people recover. Now we're moving upstream, catching people before they default and building across every stage of the consumer credit lifecycle. The one in collections today is the one who gets approved tomorrow.About the RoleWe are hiring Senior Software Engineers to help shape the future of January's platform.
