Role Summary

We are launching a green-field initiative to build a new ultra-low-latency Market Data platform. As a C++ Low-Latency Engineer, you will work on high-performance, real-time components where microseconds matter. This role is ideal for engineers with strong C++ fundamentals who want to grow in Market Data systems, low-latency engineering, and performance optimization.

Key Responsibilities

• Develop core components of the low-latency Market Data platform

• Implement and maintain market data feed handlers using binary protocols (TCP and multicast UDP)

• Work with Market Data concepts including order book modeling (L1, L2, L3)

• Optimize system performance with focus on CPU caches, memory locality, and efficient data structures

• Contribute to automated testing (unit, integration, regression)

• Profile and debug performance issues using tools such as perf, valgrind, strace, and flame graphs

• Analyze binary data dumps and troubleshoot protocol-related issues (training provided)

• Collaborate closely with senior engineers to learn and apply advanced low-latency techniques

• Participate in deployment, validation, and monitoring in QA and Production environments

• Join on-call rotation after onboarding and platform go-live

Required Experience

• 3–5 years of hands-on experience with modern C++ (C++17 or newer)

• Minimum 2 years of exposure to Market Data systems, trading platforms, real-time systems, or performance-critical software

Technical Skills

• Strong understanding of C++ fundamentals: templates, STL, concurrency, memory management

• Solid Linux knowledge and command-line proficiency

• Understanding of performance fundamentals:

  • CPU cache behavior

  • Memory locality

  • Multi-threading and synchronization

• Experience debugging and troubleshooting using tools such as perf, strace, tcpdump, or valgrind

• Ability to read or willingness to learn binary protocols and hexdumps

• Experience with Python or Go for automation (mandatory)

• Familiarity with Git/GitLab, CI/CD pipelines, and shell scripting

• Good communication skills and ability to work in a distributed team environment
