Role Requirement

We’re searching for an accomplished Senior C++ Engineer to drive the evolution of our client’s low‑latency trading platform. The successful applicant will have demonstrable experience in developing highly efficient, high‑performance real‑time systems tailored for financial markets.

Responsibilities

• Help shape the technical roadmap, architecture, and engineering standards.
• Build efficient, low‑latency trading systems with modern C++ (C++17/20+).
• Boost system efficiency by lowering latency, enhancing throughput, implementing lock‑free programming techniques, and optimizing memory management.
• Develop and manage market‑making algorithms, order routing, reference data, and risk management systems.
• Build and manage connections to crypto exchanges via FIX, WebSocket, REST, and proprietary protocols.
• Implement real‑time market data ingestion, normalization, and processing pipelines.
• Collaborate with quantitative researchers, traders, and DevSecOps engineers to transform strategic requirements into reliable, production‑ready software solutions.
• Perform code reviews, conduct thorough testing, run simulations, and use profiling tools to guarantee that the system remains stable and fast even when handling heavy traffic.
• Troubleshoot and fix live high‑frequency production problems.

Qualifications

• Broad background working with real‑time systems for financial markets, such as high‑frequency trading, market making, or proprietary trading, built with C++ to ensure low latency and high throughput.
• Strong background working with:
  • High‑performance, lock‑free code and concurrent systems
  • Multi‑threaded applications, CPU internals, and low‑level performance tuning
  • Network development using TCP/UDP, with bonus points for experience in kernel‑bypass frameworks
  • Efficient memory usage, including creating or working with custom memory allocators
  • Solid grasp of how markets function at a technical level, including order book behavior and the mechanics behind market‑making strategies
  • Practical experience connecting to digital asset exchanges and working with high‑frequency, real‑time data streams
  • Comfortable working in Linux environments, with skills in systems‑level development, performance optimization, and using low‑level debugging utilities

Preferred

• Hands‑on work with kernel bypass methods or other techniques used to achieve extremely low latency.
• Practical use of Python for automation tasks, data handling, and building early‑stage trading models.
• Solid grasp of distributed architectures, including resilience, redundancy, and systems designed for continuous uptime.
• Background in risk controls, simulation/backtest environments, or tooling used in systematic trading.
• Professional exposure to high‑speed crypto trading environments, HFT desks, or specialized crypto market‑making teams.

This opportunity offers a rare chance to shape the future of a cutting‑edge trading venture backed by a leading UAE investment group.
