Databento is a startup that builds modern APIs to get financial data. As a Series A startup, we've raised $37.8M to date, and grown our revenues by over 958% Y/Y in the past year—all with a team of fewer than 30 employees.

We’re looking for a junior systems engineer (on parity with L3 to L4 at a large tech firm) to join our systems team. Our team manages the backbone of Databento’s platform — from Ceph storage and high-throughput networking to bare metal and containerized deployments across multiple data centers. You’ll work hands-on with a 25 GbE network stack, distributed storage exceeding 4 PB, and a modern hybrid environment spanning self-hosted and cloud systems.

We offer health, dental, disability, and life insurance benefits, as well as 401(k) matching for full-time employees. We accommodate 100% remote work, with teammates living around the globe and paid in their local currency.

• DevOps/GitOps mindset.
• Prior internship experience or 2+ years in full-time systems engineering or infrastructure roles.
