Zelos

OverviewZelos 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.
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.
What we’re looking for

• Strong proficiency with backend languages (Rust, Golang) for building scalable services
• Proven track record architecting cloud-native solutions on AWS, Azure, or GCP
• Experience with modern build and deployment tooling (NixOS, Docker, Kubernetes, Terraform)
• Understanding of storage solutions such as Parquet, InfluxDB, TimescaleDB, or similar
• Familiarity with technologies like Apache Arrow plus experience with distributed databases

What to expectYou'll join a team of seasoned engineers building cutting-edge solutions for the next generation of connected systems. We value first-principlesthinking, hands-on problem solving, and collaborative engineering. As a startup, you'll have significant influence over our technical direction and the opportunity to build systems that directly impact how teams develop and deploy mission-critical hardware. We understand that no one individual knows everything. We will all learn together and from each other. We strive to build a collaborative, enriching environment conducive to personal, technical, and career growth.
CompensationZelos provides competitive compensation (salary and equity) and benefits. The salary for this role ranges from $115,000 to $180,000 per year, commensurate with experience.
