Low Latency C++ Developer

About the role

Statech Asset Management trades on Borsa Istanbul using systems it builds itself, from market data processing to order execution. It is looking for a Low-Latency C++ Developer in Istanbul (hybrid, with offices on the Anatolian and European sides) who enjoys understanding how software works, from language-level decisions to what happens in memory, on the CPU and across the network. Early-career and experienced candidates are welcome.

Key responsibilities

• Build components that receive, decode and process real-time market data efficiently and reliably.
• Develop strategy logic, trading signals and order execution modules alongside researchers and traders.
• Measure and improve latency, throughput, CPU usage, memory allocation and network behaviour under load.
• Design threading, synchronization and memory management approaches for performance-sensitive workloads.
• Develop networked applications and investigate how operating system behaviour affects performance.
• Detect defects, investigate unexpected behaviour and improve monitoring and recovery.
• Build reusable components and improve testing, profiling and development automation.

Required profile

• Solid C++ foundations: ownership, object lifetimes, RAII, templates and the Standard Library, with attention to data structures, allocations and memory access patterns.
• Comfortable developing on Linux and understanding processes, threads, virtual memory, I/O and system calls.
• Understanding of concurrency and networking fundamentals, including shared state, synchronization and TCP, UDP and sockets; multicast is a plus.
• Evidence-driven problem solving: breaks problems down, forms hypotheses and verifies them with measurements, using tools such as GDB, perf or Valgrind.
• Clear communication, collaboration, Git and code review, and comfort reading technical documentation in English.

Nice to have

• Familiarity with trading systems, exchange connectivity, order management systems or market microstructure.
• Advanced optimisation: lock-free programming, CPU affinity, NUMA, kernel bypass or network stack optimisation.
• Research tooling and machine learning: Python, NumPy or pandas, time-series analysis, model validation.
• FPGA development or other hardware-accelerated systems.

What we offer

• Competitive salary and performance-based bonus.
• Private health insurance and 15 days of paid annual leave.
• Compensatory time off for overtime.
• Work on systems used in live trading, with hybrid working and direct communication within a small team.

Working hours align with Borsa Istanbul's trading schedule, so availability during trading hours is required, including on remote days. Hiring involves an introduction and technical interview, a technical project and a solution discussion.
