About The Position

Bankjoy is a Y Combinator and Bessemer Venture Partner backed FinTech startup. We are changing the way community banks and credit unions do business, enabling them to become tech-driven and digital first.

Our mission is to revolutionize banking tech infrastructure by leading digital transformation at financial institutions — big and small. We are looking for a Lead Software Engineer to drive the technical direction and execution of Bankjoy's new kids and family financial empowerment product. This is a hands-on technical leadership role. You will own the architecture, lead a small high-performing engineering team, and work closely with Product, Design, and QA to build a product that is secure, scalable, and genuinely delightful for families and their children. You'll be embedded in a fast-moving startup environment where your decisions directly shape the product. The ideal candidate brings deep experience in banking, payments, or financial wellness technology, with strong proficiency in Angular and .NET Core, and ideally some exposure to mobile app development. You must be based in or willing to work Eastern Time Zone hours.
