Software Developer – Full Stack (Internal Applications)

About United Contractor Services United Contractor Services is a national specialty contractor and one of the Top 50 Walls and Ceilings contractors in North America. Our project teams deliver commercial interior scopes, including metal framing, drywall, acoustical ceilings, EIFS, stucco, painting, and Division 8 and 10 Specialties, across multiple markets.

You won't be closing tickets someone else wrote. You'll sit down with the people doing the work, figure out what they really need, build it, ship it, and keep it running.
