I can certainly share some of the meatier areas that engineers at Gusto work on. - Calculating payroll and filing quarterly and annual forms are very complicated tasks that (a) is different in every state and (b) changes frequently as federal, state, and local tax laws change. Doing payroll in 50 states is similar to doing payroll in 50 different countries - Benefits is similar to Payroll in the sense that it's also very different in each state. The business logic is complex and a significant amount of engineering work goes into simplifying it for us customers - Because we move billions of dollars per month through the banking system, we have a lot of the same technical challenges as a Stripe, Square, Paypal, Venmo, etc. We have a dedicated FinTech, Payments, and Risk teams for this. - Security is super important to us, since we have a lot of PII/PHI and financial informaiton - Gusto is about 600 employees today and we invest in lots of internal tools for non-engineering functions, an enterprise data warehouse, and security. - We are also looking into what the future of payroll looks like. A personal goal of mine is to rid the world of the concept of a "payday". Why shouldn't employees get paid whenever they want for the work that they did? https://techcrunch.com/2018/06/21/gusto-flexible-pay/ https://techcrunch.com/2018/06/21/gusto-flexible-pay/ - Technical debt: When you grow as fast as Gusto does, you inevitably accrue technical debt and it's important that we carve our engineering resources to keep that low. There's a lot more in there, but hopefully it gives you a sense of how 100 engineers can add up pretty quickly!
