Senior Backend Engineer
@ Human Interest

Human Interest is on a mission to ensure that people in all lines of work have access to retirement benefits. 

Nearly half of all working Americans are not saving enough for their future. Too often it’s because they are employed by a company that doesn’t offer a retirement plan. Human Interest is changing that by making it affordable and accessible for small and medium-sized businesses to offer employees a path to financial independence through retirement savings.

We’re a high-growth tech company changing the retirement industry. We are backed by a number of investors. Most recently, this includes funding from Marshall Wace and Baillie Gifford, as well as top investors such as BlackRock, TPG (The Rise Fund), SoftBank, Glynn Capital, NewView Capital, USVP, Wing, Uncork, and more.

Our engineering organization aims to redefine the retirement services space with software that provides an effortless, efficient, scalable, and reliable user experience. 

• We value continuous improvement, emphasizing documentation, security, consistency, and scalability.

• We help each other be better engineers, ensuring we leave things better than we found them.

• We are customer-focused, ensuring our software improves the customer experience

About the Recordkeeping team

As a foundational platform, the Recordkeeping team plays a crucial role in the company’s success by accurately recording all financial transactions.
