Role Overview As a Senior Software Engineer , you will take leadership in designing, building, and scaling high-performance trading systems. You will be driving architectural decisions, mentoring others, and ensuring the reliability, latency, and correctness of our production systems. Your role will bridge between quant research, trading operations, and engineering excellence. Key Responsibilities Lead design, development, and ownership of large, complex C++ systems: engines for order execution, market data ingestion, risk, connectivity, and downstream services. Architect systems for low latency, high throughput, fault tolerance, and operational resilience. Identify performance bottlenecks across software/hardware layers; lead initiatives to reduce latency, increase capacity, and improve stability. Mentor and lead other engineers through code reviews, pairing, and driving best practices in code structure, testing, and performance. Liaise closely with quant researchers and traders: influence product and strategy design, ensuring designs satisfy functional, non-functional, and latency constraints. Drive infrastructure and tooling improvements: monitoring, observability, deployment pipelines, build systems, profiling frameworks, and latency measurement tools. Stay up to date with new technologies and architectures (e.g. kernel bypass, RDMA, NUMA, CPU/GPU/FPGAs) and evaluate them for potential adoption. Qualifications Required 5+ years (often 7+) of experience building production C++ systems, ideally in latency-sensitive or real-time environments. Deep expertise in modern C++ (C++17/20/23), templates, metaprogramming, memory management, and allocation strategies. Strong understanding of concurrency: multi-threading, lock-free programming, synchronization, hardware caches, and memory fences. Proven track record in optimizing performance (latency, throughput); experience profiling and benchmarking at a low level. Experience with network programming: TCP/UDP, protocol desi
