Sr .Net Full Stack Developer

About Spire Soft LLC

We are a bootstrapped, remote-first product startup. We build software that works—currently powering productivity through a SaaS suite in the Project Management and Legal-Tech sectors.

As we expand, we need builders who thrive with high autonomy. We don’t micromanage; we expect extreme ownership.

We hire unconventional thinkers who view "I don’t know" as an invitation to learn and who prefer building products over just "clearing tickets."
