About Atomic Financial:
At Atomic, we're building financial connectivity that enables the fintech and financial services ecosystem to connect consumers to the data in their payroll accounts, drive conversions of direct deposit linked products, verify income and employment history in real-time, update the card-on-file in merchants, and manage their subscriptions and bills.
We believe consumers should be able to easily share their own payroll data to improve their financial outcomes. However, connecting to the data is cumbersome, met with non-specialized solutions, which is why we founded Atomic.
Signing up for a mortgage? We make it so you can submit your paystub and W-2 in seconds. Getting a credit card? We can verify you're employed in real-time. Switching banks? We can instantly and securely move your direct deposit to the financial institution of your choice.
We build user-permissioned connectivity into payroll and merchant systems. Our products are used by some of the largest financial brands in the world, and we're funded by some of the best investors in the world, including Greylock (investor in LinkedIn, Nextdoor, Airbnb, and others), Core Innovation Capital (invested in Ripple, Nerd Wallet, and others), and Portag3 (invested in WealthSimple, Albert, and others).
Our team has been the reason for our success thus far, and it will be the reason we continue to succeed. We're looking to continue to grow our world-class team to shape the tomorrow of Atomic.
Atomic's Culture is:
Innovative - we're on the bleeding edge of the fintech space empowering some of the coolest brands in the world.
Transparent - we believe in being transparent with everyone in our company. Feel free to ask how we deliver on this promise during the interview process.
Customer-centric - we're wild about our customers.
Fun - We all spend a big portion of our lives with colleagues, so we want it to be fun. Our last company activity was a virtual escape room. Each team competed and we had a blast!
