ReOrbit is looking for an IT Lead – Infrastructure, Operations & Support to build and scale the infrastructure, operating model and service foundations that enable the company to grow. As our IT Lead – Infrastructure, Operations & Support, you will take ownership of how ReOrbits core IT infrastructure and operations are designed, managed and scaled.
