Were partnered with a high-growth construction-tech startup thats transforming how a $12T industry works by connecting legacy systems to modern SaaS tools through a unified API and automation platform. Theyre already cash-flow positive, scaling quickly, and solving real, complex problems with technical depth and speed.
The founding team is tight-knit, highly technical, and has worked together for over a decade. Theyre solving unsexy, overlooked infrastructure problems that have massive impact and theyve eliminated many of the early-stage risks youd usually find at startups.

Build and scale high-performance backend systems, unifying fragmented construction software through a standardized API
Interface with complex legacy systems (SQL, DLL, API-based) to modernize how data moves in construction
Design features that scale across dozens of systems (pagination, filters, auth, caching, etc.)
Contribute to both backend and frontend (React) projects that dogfood their own API
Help build a robust testing and release pipeline across 1000+ endpoints
