Job Description

We are looking for a

Senior C#/.NET Developer

to join an investment fund that leverages advanced algorithms for cryptocurrency trading.

Responsibilities

Design and develop a high-performance trading platform with low-latency requirements. Implement market data integration and processing via FIX/FAST/REST/WebSocket protocols: Build and aggregate quote streams, consolidate order books. Optimize incoming data processing (low-level parsing, buffering, zero-copy, minimizing allocations). Develop and enhance market-making and order execution algorithms, including options market-making strategies. Optimize algorithms using SIMD, low-level optimization, and profiling. Optimize networking and socket handling (latency minimization, efficient I/O model usage). Write zero-allocation C# code, analyze and eliminate GC overhead. Develop C# interoperability with native libraries. Participate in technical design: choosing architectural solutions for high-performance and scalable systems. Monitor system performance and stability, identify bottlenecks, and resolve them. Participate in testing (unit/integration), load testing, and write automated tests for key components.

Requirements

Proficiency in Russian (C2 level).

Excellent command of C# (.NET 7+). Experience with interop development. Deep understanding of multithreading: memory models, synchronization, lock-free techniques, concurrent collections. Proven ability to write zero-allocation C# code: identifying/eliminating allocations, understanding CLR/GC internals. Strong knowledge of trading system protocols (FIX, FAST, WebSocket, TCP, UDP, etc.). Broad expertise in high-performance architectures: designing low-latency, distributed, and scalable systems. Hands-on experience with latency optimization: profiling, hot-spot analysis, bottleneck elimination. Experience in HFT projects. Experience developing options market-making strategies, with understanding of options markets and risks. Knowledge of matching engine principles, order handling mechanics, and order book dynamics. Proficiency with profiling tools (dotTrace, PerfView, native code profiling, etc.). Experience with monitoring and logging systems (latency and performance metrics collection). Strong self-organization and ability to work remotely: independent task planning and reporting.

Conditions

Work format:

fully remote, with occasional business trips to countries with favorable climates (covered fully or partially by the company, negotiable).

Team:

friendly and professional, combining experienced developers and quant analysts. Regular technical meetings, knowledge sharing, and code reviews.

Tasks:

intellectually challenging, focused on building and optimizing low-latency trading systems, exploring new approaches and technologies.
