Senior Software Engineer

San Francisco, CA


We are a modern, embedded payroll provider that helps empower companies to build their own unique payroll service. On top of our easy-to-use payroll API we are pioneering an all inclusive tax engine to democratize a broken and cumbersome process providing accessibility to small, medium and large businesses and helping Americans get paid.

Backed by over $14 million in funding by top investors such as Y Combinator, Spark Capital (Marqeta, Coinbase, Affirm) and Robinhood's Founder; Vlad Tenev we are projected to be a forerunner in embedded payroll with an industry amassing billions of dollars in untapped revenue.

Our mission is to empower companies to become their own fin-tech company using our simple, seamless and forward thinking payroll technology and we'd love to learn more about you and how you could be a fit for our growing team here in San Francisco!


As one of the founding Senior Software Engineers here at Zeal you will have an opportunity to work on end-to-end product development for our embedded payroll platform. You will be one of the key stakeholders in how we develop our products and will have a lot of autonomy to work the way you want. We believe in providing as much time for deep coding work as possible, so we don't flood your calendar with strenuous meetings. We want you to do what you do best - and that is to solve creative problems in the fin-tech landscape.

As part of the founding engineering team, you will be able to help craft as well as shape the future of Zeal's engineering department as well as our product.

You will have a seat at the table and get to chat with stakeholders to understand the why behind what you develop. Most importantly, we believe in shipping product fast, but pushing maintainable, well-tested code and available, robust systems. If you need an extra few days to perfect something, we want you to feel empowered to do so. Overall, we're a pretty cool team where you'll get to wear many hats and have fun doing it. If this is something you'd be interested in we'd love to connect!
