Databento is a startup that builds modern APIs to get financial data. As a Series A startup, we've raised nearly $30M to date, and have 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 software engineer (on parity with L3 to L4 at a large tech firm) to join our core engineering team. Our core engineering team is responsible for all things C/C++ and Rust and the most performance-sensitive parts of our codebase. You'll be working with almost 20 PB of data, with thousands of bare metal CPU cores at your disposal.

- Write message parsers and feed handlers for direct market data feeds from trading venues.
- Optimize existing codebase for high throughput (millions of messages per second, up to 40+ gigabit) and low latency (measured in nanoseconds).
- Implement tools and libraries for petabyte-scale data processing and analysis.
- Collaborate with systems team to implement best practices for build, deployment, CI/CD.
- Implement monitoring and improve application uptime.
- Ensure smooth feature rollouts and updates.
Preferred background:
- Prior internship experience or 1 to 3 years of full-time software engineering experience, preferably at a trading firm, tech company or high-growth startup.
- Strong proficiency in C/C++ or Rust.
- Knowledge of systems programming, algorithms, data structures, multithreading, networked I/O, serialization, CPU architecture, kernel, and compilers.
- Experience working with multiprocess environments.
