Low-Level Software Engineer

Job Description

A leading quantitative trading firm is looking for an Embedded C++ Software Engineer to join its high-performance engineering team. This is an opportunity to work on some of the most latency-sensitive systems in electronic trading, where software performance has a direct impact on the business.

You’ll work across the trading technology stack, building and optimizing high-performance, low-latency C++ systems and solving complex systems-level performance problems. The role sits close to both the hardware and trading environments, giving engineers significant ownership over the technology they build.

What you’ll work on:

\n
• Design and develop low-latency, high-throughput trading systems
\n
• Optimize C++ applications for latency, throughput, and reliability
\n
• Work at the intersection of software and specialized hardware, including FPGA/ASIC-based systems
\n
• Identify performance bottlenecks across CPU, memory, networking, and system architecture
\n
• Collaborate closely with hardware engineers, traders, and other engineering teams
\n
• Own projects from design and development through production deployment and optimization
\n

What they’re looking for:

\n
• 2+ years of professional modern C++ development experience
\n
• Strong understanding of performance-sensitive or real-time systems
\n
• Experience with Linux, multithreading, concurrency, networking, memory management, and/or CPU architecture
\n
• Experience developing software that interacts closely with hardware is highly desirable
\n
• Low-latency trading experience is a plus, but strong engineers from other performance-critical environments are encouraged to apply
\n
• BS/MS in Computer Science, Computer Engineering, or a related technical field
\n

This is particularly well suited to engineers who enjoy getting deep into C++ performance, systems internals, hardware interaction, and latency optimization while working in an environment where engineering is central to the business.
