You will focus on developing and optimizing ultra-low-latency systems that facilitate high-speed, high-volume equity trading, ensuring the exchange remains fast, reliable, and resilient.\nWhat you will do in the role\nDesign, develop, and maintain low-latency trading systems that ensure efficient and secure execution of equity trades. \nWork on matching engines, order routing, and market data distribution systems to optimize trade execution performance. \nBuild systems to process millions of transactions per second with minimal latency and maximum throughput. \nImplement real-time processing pipelines for financial data, ensuring high accuracy and consistency in time-sensitive environments. \nConduct latency analysis, performance benchmarking, and system optimization using advanced profiling techniques. \nCollaborate with exchange operations teams, traders, and other developers to meet the rigorous performance demands of equity markets. \nManage and optimize network protocols for market data distribution, including the handling of TCP/IP and UDP connections for rapid data dissemination. \nDevelop robust systems to handle bursty, high-throughput market conditions, ensuring fault tolerance, high availability, and minimal downtime.\nImplement low-latency algorithms and strategies for trade execution while ensuring compliance with exchange regulations.\nRequired Skills\nExpert proficiency in low-latency programming, especially with modern C++, Java and Kotlin \nIn-depth knowledge of multi-threading, concurrency, and parallel programming to develop efficient real-time systems. \nExtensive experience with high-frequency, low-latency software systems, ideally in financial markets, exchanges, or trading environments. \nStrong understanding of network programming and socket communication (e.g., TCP/IP, UDP) for market data distribution and order execution. \nFamiliarity with matching engines, order books, and equity trading protocols (e.g., FIX, OUCH, ITCH). \nExperience optimizing software for low-latency I/O, memory management, and CPU cache utilization. \nKnowledge of kernel bypass techniques such as DPDK, RDMA, or TCPDirect for minimizing network latency. \nExperience with Linux tuning and real-time operating systems to enhance system performance. \nProficiency in latency measurement and profiling tools (e.g., perf, gdb, Valgrind) for analyzing and optimizing system performance. \nFamiliarity with distributed systems, message buses, and event-driven architectures for building scalable, fault-tolerant applications. \nUnderstanding of financial markets, equity instruments, and market microstructure. \nPreferred Qualifications\nKnowledge of high-frequency trading environments or other asset classes beyond equities. \nFamiliarity with low-latency storage solutions for market data. \nKnowledge of Reg NMS and other regulatory requirements related to equity trading\nStrong analytical and problem-solving abilities, particularly under high-pressure situations. \nAttention to detail with a strong focus on precision and performance. \nAbility to communicate complex technical concepts to both technical and non-technical stakeholders. \nTeam player with a collaborative mindset, but able to work independently on complex tasks. \nAdaptable to the fast-moving, dynamic nature of financial markets and technological innovation.","description_format":"text","description_chars":3523,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"United
