Company Overview

At Wisetack, we’re building financially-responsible consumer lending products that help service-based businesses thrive.

Wisetack is a well-funded ~100 person startup founded in 2018 by a team of experienced fintech veterans, with a leadership team that comes from PayPal, LinkedIn, Lending Club, Affirm, Amazon, and other top companies. We’re backed by leading VCs, including Insight Partners, Greylock, and Bain Capital Ventures, (investors in Airbnb, LinkedIn, Instagram, Dropbox, and many more.)

We raised a $45M Series B last year and since then, we've invested in the team and the product and signed a slew of new partnerships. This is a fun stage in any company's lifecycle where we've got the core foundation built, a healthy growth rate, and a clear path to success, but you'd still be joining early enough to help shape the future of the company.

Business Insider called us one of the 70 most promising startups changing the world of finance, LendIt selected us as this year's winner in the Best Emerging Lending Platform category for their Fintech Industry Awards, and we were just named to the inaugural SMBTech 50 list (perhaps you saw us on the billboard in Times Square?) The external recognition is great, but we're equally -- if not more -- happy with the recognition from our customers. Our current NPS rating is a sky-high 78. We're proud that we're building a product that customers love and we believe that this is the most important foundation of a great company.

Our Engineering team principles

Everyone is an engineer. No matter what their title is, everyone contributes to the code. Everyone delivers.
Initiative and ownership. We want every team member to lead the work they do. Design the best solutions and implement them. Ask for help from others when you need it.
One team. We are low ego and support each other.
Learning and growth. We believe growth is a huge motivator. We want everyone on the team to have an opportunity to learn and grow in their career. If you are smart and want to learn, you should be with us even if you don't have all the skills we need at the moment.

Check out this post from our blog where we go into more detail about these principles.

The person in this role must be based in the United States and must be authorized to work in the US. Unfortunately, we are unable to offer visa sponsorship. SF Bay Area candidates can choose to work from our San Francisco office (whenever we return to an office) or from home most days. If remote, you should be able to come to San Francisco 4-6 times per year.


We offer competitive salary and equity packages, as well as medical, dental, and vision insurance, a Learning & Development stipend, a 401k plan, and a growing number of other standard and not-so-standard benefits.

More than that, though, we offer a career-defining opportunity for the right candidate. Spend a little time on our About Us page, researching our team and our values, and check out our Press page and our blog for more background on who we are and what we do. If you think this might be a fit, we’d love to hear from you!

Our Remote Policy

For now and the near-term future, we are fully remote. We may have some sort of office setup within the next year, and that office will be located in San Francisco. When we do, SF-based employees will have the option to work from an office, if they so choose. That said, most roles at the company, including this one, can be fully remote within the US, and some contractor roles may be available outside the US. Our workforce is currently spread across 15 different US states, and 4 different countries.

Yes, we're still hiring!

We know that some tech companies face a difficult situation and have announced layoffs in response to changes in the venture funding market as well as broader economic pressures. Not Wisetack! Our business is doing incredibly well and growing at a fast pace. We also have plenty of capital, allowing us to continue adding key members to our team while remaining very prudent with our spending, as we always have.
