The Systematic Platform Execution & Exchange Data (SPEED) Team is at the core of Millennium’s Equities, Quant Strategies, and Shared Services Technology organization, powering the firm’s lowest latency solutions for systematic and high frequency trading. SPEED delivers the live trading and market data platforms used by portfolio managers and risk systems, including Latency Critical Trading (LCT), DMA OMS (Client Direct), DMA market data feeds, packet capture (PCAPs), enterprise market data, and intraday data services across latency tiers from sub100 nanoseconds to millisecond sensitive workflows. By building and operating this execution and data infrastructure, SPEED enables portfolio managers and researchers to compete effectively in the most time-critical markets.
As a Senior Feature Framework Developer on SPEED, you will design and build the most latency-critical components of our trading system. We are aiming for the best in class here. Additionally, you will work on making the platform more scalable. The system must grow along with data volumes while keeping a small footprint. You will collaborate with systems (Linux, network) engineers, senior software engineers as well as senior quantitative researchers, operate and optimize these systems in production, and have clear opportunities to grow into technical and team leadership as the effort scales. This role offers the chance to work end-to-end mission critical HFT systems in a highly technical environment, directly shaping the performance, reliability, and evolution of platforms that are central to Millennium’s trading edge.
We are looking for a C++ engineer to design and build high‑performance, low‑latency applications that process large volumes of real‑time data. You will work on systems where nanoseconds and throughput matter, optimizing every layer from algorithms and data structures to networking and OS interaction.
