Software Engineer II

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’ve raised more than $700M in primary and secondary financings and 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.
