About Double (Formerly Keeper)

Bookkeepers today are stuck working in excel spreadsheets and homegrown project management solutions to support their clients. Double is on a mission to change that.

With our all-in-one tool, bookkeepers can manage their work, communicate with clients, catch hard-to-find errors, and deliver reports to help their small business customers make smarter strategic decisions.

Founded in 2021, Double has raised $12M in funding, backed by leading tech investors like Y Combinator and founders at top startups like Lattice, Front, Superhuman, Plaid, and more. Double currently helps thousands of bookkeepers and accountants manage the books for startups and small businesses across the US.

We're growing fast, and we're looking for a Senior Full Stack Engineer to accelerate our product and help our customers better serve their small business clients.
