Senior C++ Engineer Electronic Trading

A leading global trading organization is undertaking a ground‑up rebuild of its equities algorithmic trading platform, with a clear mandate: set the benchmark for electronic equities trading. This is a front‑office engineering role backed by significant long‑term investment. The platform sits at the core of the equities business and directly impacts trading performance across global markets.

The Opportunity

You'll work on business‑critical trading systems that operate at extreme scale and under tight latency constraints. Engineers in this group have real ownership - influencing architecture, design decisions, and delivery rather than operating as downstream support.

What You'll Be Doing

• Designing and building low‑latency, high‑throughput equities trading systems
• Developing core components such as order routing, market access, matching, and real‑time risk
• Working side‑by‑side with traders and front‑office stakeholders to translate trading needs into production systems
• Optimizing performance across the stack (concurrency, networking, OS‑level tuning)
• Ensuring platforms meet the highest standards for reliability, resiliency, and scalability
• Contributing to architecture decisions for the next generation trading stack

What They're Looking For

• Strong professional experience building performance‑critical systems in C++
• Deep understanding of multithreading, concurrency, and low‑latency design
• Solid Linux systems knowledge (including OS and kernel‑level concepts)
• Experience with electronic trading systems, market data, or order management
• Comfort working in demanding, real‑time production environments
• Ability to engage directly with the business and take full ownership of outcomes
• Experience in equities, derivatives, or multi‑asset trading environments
• Network programming (TCP/IP, messaging middleware)
• Exposure to Python or other scripting languages
• Familiarity with modern CI/CD and agile delivery in front‑office teams

Why This Role

• True front‑office impact - your code directly affects trading results
• High visibility, high ownership engineering environment
• Long‑term platform rebuild rather than incremental maintenance
• A culture that values engineering quality, performance, and accountability
