About The Role
We're hiring a Systems Integration Engineer to design, build, and maintain the connective tissue between Nscale's rapidly expanding application landscape. As we scale from 500 to 1,000+ people and prepare for IPO, our internal systems need to work together seamlessly - not as isolated silos.

You'll define integration patterns, build automation workflows, and ensure data flows reliably across the enterprise. You'll work closely with the Senior Director of Systems Integrations to translate business requirements into technical solutions, evaluate integration tools and platforms, and establish standards that enable the company to scale without creating technical debt. This role sits at the intersection of enterprise architecture, solution design, and hands-on implementation.
