Job summary

Databento is seeking a midlevel to senior IC to join our core engineering team. You will own all things C/C++ and Rust, building high-performance server applications and direct market data feeds. Work on optimizing throughput and latency across a data-heavy stack with thousands of cores and petabytes of data.

The role emphasizes low-level optimization, systems programming, and collaboration with a remote-friendly team. If you enjoy performance engineering and financial data, this is a strong fit.

Qualifications

• An interest in low-level optimization and performance engineering.
• Comfortable with lldb/gdb.
• Knowledge of systems programming, algorithms, data structures, multithreading, networked I/O, serialization, CPU architecture, kernel, and compilers.
• Strong proficiency in C/C++ or Rust.
• Experience working with multiprocess environments.
• 5+ years of full-time software engineering experience, preferably at a trading firm, tech company, or high-growth startup.
• Good communication skills and work ethic for a remote workplace.
• An interest in financial data or algorithmic trading.

Responsibilities

• Design, develop, and maintain high-performance server applications in C/C++ and Rust.
• 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+ gigabits) and low latency (nanoseconds).
• Implement tools and libraries for petabyte-scale data processing and analysis.
• Collaborate with the systems team to implement best practices for build, deployment, CI/CD.
• Implement monitoring and improve application uptime.
