The Systematic Platform Execution & Exchange Data (SPEED) Team is at the core of Equities, Quant Strategies, and Shared Services Technology organization, powering the firm's lowest-latency solutions for systematic and high-frequency trading. SPEED delivers the live trading and market-data platforms used by portfolio managers and risk systems, including Latency Critical Trading (LCT), DMA OMS (Client Direct), DMA market data feeds, packet capture (PCAPs), enterprise market data, and intraday data services across latency tiers from sub-100 nanoseconds to millisecond-sensitive workflows. By building and operating this execution and data infrastructure, SPEED enables portfolio managers and researchers to compete effectively in the most time-critical markets.
We are looking for a C++ Engineer to help design, build, and enhance high-performance applications that process large volumes of real-time data. This role is suited to engineers who enjoy solving systems and performance challenges, writing reliable production code, and working closely with cross-functional teams to deliver robust technical solutions.
Depending on the assignment, you may work on components related to real-time data processing, analytics, messaging, infrastructure, or performance-sensitive services. We are hiring across several areas, so the exact domain focus may vary.
Key Responsibilities

• Design, implement, and maintain scalable, high-performance C++ applications and services.
• Improve existing systems for performance, reliability, maintainability, and efficiency.
• Contribute to components involving real-time data processing, networking, messaging, and I/O.
• Investigate and troubleshoot issues across application, system, and occasionally network layers.
• Collaborate with engineering, infrastructure, and business stakeholders to translate requirements into practical technical solutions.
• Write clean, well-tested, production-quality code and documentation.
• Participate in code reviews, design discussions, and ongoing improvements to engineering practices.
• Support delivery and operation of systems in production environments as needed.

Required Qualifications

• Strong proficiency in modern C++.
• Professional experience building production software in C++ environments.
• Experience working on performance-sensitive, distributed, or real-time systems is strongly preferred.
• Solid computer science fundamentals, including data structures, algorithms, memory management, and concurrency.
• Experience with debugging, profiling, and performance analysis tools.
• Familiarity with Git and standard build tooling such as CMake or similar.
• Strong problem-solving skills and ability to work effectively in a fast-paced environment.
• Good communication skills and ability to collaborate across technical and non-technical teams.

Nice to Have

• Experience in low-latency or high-throughput systems.
• Exposure to Linux systems, networking, or systems-level performance tuning.
• Familiarity with Python, Bash, or similar scripting languages for tooling and automation.
• Experience in financial services, market data, trading systems, or other data-intensive domains.
• Exposure to cloud platforms, HPC/research environments, or large-scale data platforms.
• Familiarity with modern developer productivity tools, including AI-assisted coding tools.
• For Analytics-Oriented Roles, some assignments may benefit from experience with:
  • KDB+/q or large-scale time-series / market data environments
  • Data analysis tooling such as pandas, PyTorch, or Apache Arrow
  • Basic statistics or analytical workflows

Personal Attributes

• Practical, hands-on engineer with strong ownership mindset
• Comfortable working across the software lifecycle, from development through production support
• Collaborative and adaptable, with a focus on delivering value
• Interested in building reliable, efficient systems and continuously improving them
• High accountability and ownership; able to self-manage time, set priorities, and meet deadlines.
