Staff Software Engineer, Agentic Infrastructure

Overview Join Relativity Space to own and evolve the agentic infrastructure that powers cutting-edge aerospace research. You’ll work within Dark Matter Lab to turn prototypes into production-grade systems, enabling reliable multi-agent workflows and local LLM inference. You’ll collaborate with forward-deployed engineers to package solutions for internal and customer use and contribute to open-source projects. This role offers hands-on impact shaping the stack that connects hardware, software, and operations across sites. You’ll operate at the intersection of reliability, security, and practical engineering in a high-performance, innovative environment.
