As a Principal Software Engineer, you will lead the computational infrastructure that the next generation of large-scale neuroscience research will depend on. Working closely with scientists and hardware engineers, you will span the full stack of our research systems, including instrument control, data acquisition, and analysis, translating open-ended experimental goals into reliable software. The problems are latency-sensitive, multi-modal, and deeply interdisciplinary. You do not need a background in neuroscience to apply; we are looking for an exceptional, pragmatic engineer who enjoys solving hard, interesting problems and picks up the science as they go. As a principal engineer, you will define the technical roadmap across systems, mentor other engineers, and shape how neuroscience and engineering work together at Astera.
