Senior Software Engineer, Integrations

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

More than 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 fintech company changing the retirement industry. We are backed by a number of investors. 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.

As a Senior Software Engineer on our Integrations team, you will build integrations and automate processes that manage connections to hundreds of payroll providers and other 3rd parties that make up the backbone for servicing 401(k) plans and making our customers happy.
