About Dusk Labs
We are an engineering-driven development agency that helps early-stage companies kick-start their engineering operations, or helps mid-stage companies develop greenfield software projects.
We strive to maintain expertise at the cutting-edge of technology, take pride in doing high quality work, and differentiate ourselves from other development teams through our results.
You’ll be a good fit if you are passionate about technology, like getting things done, learning new things, and working on interesting problems.
You’ll also be a good fit if you like freedom. We respect your autonomy and don’t have strict rules on how and when you work. We only have occasional meetings, and prefer asynchronous communication. When we do have meetings, we try to knock them out all at once to maximize uninterrupted work time.
If you’ve got a public record of your work, whether that’s a body of talks and publications, or especially open source software projects, we’d love to see it. You’ll go to the front of the interview line.
