Overview
Zelos is building the data platform for mission-critical systems, helping teams observe, control, and test their systems on a collaborative platform – from prototype to production. Founded by Tesla and Neuralink engineers, backed by YC and Human Capital.
About the role
As a Backend Software Engineer, you will build and maintain distributed systems that process and store very high-frequency time-series data. This includes designing scalable storage solutions that can manage large datasets in real-time, optimizing system performance, and engaging with customers to deliver effective data solutions. Our backend system is primarily built in Rust, and leverages technologies such as Apache Parquet and Arrow.
