Software Engineer (C++/Rust)

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.

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

• 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.
