Senior Developer Tools Engineer

As the founding member of the Developer Experience (DevX) team, you will shape how engineers interact with our compiler infrastructure. You will design and build developer tools for profiling, debugging, and performance introspection across our compiler stack. You will create client-side tooling that transforms server-side compiler telemetry into clear, actionable information for engineers, and develop interfaces that expose hardware performance metrics and interrupt data in meaningful ways. You will build GPU debugging capabilities and visualization tools to help engineers understand execution on heterogeneous hardware, and define formats and protocols for debug information exchange, working with standard debugger formats (DWARF, JTAG) and object file formats (ELF, COFF). You will collaborate closely with compiler engineers and internal engineering teams to understand their needs and iterate on tooling, with a path toward external customer-facing tools.
