Construction is an industry built on change. With each new project, we change skylines, strengthen communities, and transform cities for the better.‍ But the reality isn’t always so simple. Between compliance and change orders, false starts and permit delays, the construction industry has a paperwork problem—especially when it comes to getting paid.‍ Cash flow is the lifeline of any contractor’s business, but billing is painful and slow. With so much manual work involved, a small, honest mistake can hold up millions of dollars in cash flow. And even when things go right, the time and effort it takes to get paid takes away from the work that really matters. We believe that when you free up payments, you free up people to take on whatever’s next. We started Siteline to give construction teams a financial foundation to build on. Because when people are on the same page about getting paid, they can focus on whatever's next—whether that’s a new idea, a new project, or more time with their family. We’re reimagining construction finance to help contractors get paid, grow their business, and build a better future for all of us.

We’re an early stage, well-funded startup team with a proven track record of shipping open source software with global adoption. We put a premium on respectful, clear, and complete communication, and we expect each other to be creative, curious, effective, and empathetic. We believe deeply that the right tools and abstractions enable not just technological transformation, but also organizational transformation. We strive to put the user and their hard work at the center of our decision making. In practice, that means we are looking for engineers who want to write clean APIs and helpful error messages, and who always try to understand user needs when designing a new system. All of our open source work is done publicly. You can gain context about how we collaborate as a team and the problems we work on by exploring GitHub (github.com/dagster-io/dagster) and looking at our code reviews (github.com/dagster-io/dagster/pulls).
