Full Stack Engineer, Growth

Constrafor is rebuilding the financial infrastructure behind one of the largest industries on the planet and we're doing it fast! Construction moves trillions of dollars a year, yet it still runs on outdated processes, cash flow guesswork, and paperwork chaos. We're the SaaS and fintech platform fixing that, giving General Contractors and Subcontractors the tools to manage procurement and financial transactions the way modern companies actually operate. Backed by $30M+ in VC funding and scaling fast, we're not just building software, we're building the operating system for construction finance. If you want your work to have real, tangible impact on an industry that touches literally everything around you, this is that opportunity.
