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.\nAs 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.\nWe 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.\nPrincipal Responsibilities\nDesign, implement, and maintain high-performance C++ services handling high message rates and low-latency workloads.\n\nOptimize existing components for latency, throughput, and CPU/memory efficiency.\n\nDevelop and tune networking, messaging, and I/O layers to handle large data volumes reliably.\n\nProfile and debug performance issues at application, OS, and network levels.\n\nCollaborate with quantitative, trading, and infrastructure teams (or analogous business/tech teams) to translate requirements into robust technical solutions.\n\nWrite clean, production-quality code with appropriate tests and documentation.\n\nParticipate in code reviews, design discussions, and continuous improvement of engineering practices.\n\nRequired Qualifications\nStrong proficiency in modern C++ (C++17/20 or later) 5+ years of experience\n\nAnalytics Focus:\nKDB / Q Experience for large market data\n\nModern data analysis with pytorch, pandas and modern tooling including Apache arrow\n\nFamiliar with basics statistics as applied to financial research\n\nProven experience building performance-critical, real-time, or low-latency systems (e.g., networking, trading systems, telemetry, gaming engines, or similar).\n\nStrong knowledge of computer science fundamentals: data structures, algorithms, memory management, and optimization.\n\nExperience using profiling, benchmarking, and performance analysis tools (e.g., perf, valgrind, flame graphs, CPU/memory profilers).\n\nProficiency with version control (Git) and standard build systems (CMake, Ninja, etc.).\n\nExcellent problem-solving skills and attention to detail; ability to work in a fast-paced environment.\n\nStrong interpersonal skills with a proven ability to navigate large organizations, create cross-team synergies, and influence outcomes.\n\nHigh accountability and ownership; able to self-manage time, set priorities, and meet deadlines.\n\nPreferred Qualifications\nExperience with kernel bypass or user-space networking technologies (e.g., DPDK, RDMA, VMA, Solarflare/OpenOnload) - helpful but not required.\n\nFamiliar with AI productivity enhancing coding tools\n\nExperience in financial markets, market data distribution, order routing, or exchange connectivity.\n\nExperience with monitoring/telemetry for high-performance systems (latency histograms, throughput metrics, SLAs).\n\nFamiliarity with scripting languages (e.g., Python, Bash) for tooling and automation.\n\nAI: Familiar with AI productivity enhancing coding tools.\n\nPersonal Attributes\nObsessed with performance, measurement, and data-driven optimization.\n\nComfortable owning features end-to-end and operating in a production environment.\n\nClear communicator who can work closely with both technical and non-technical stakeholders.\n\nProactive, self-directed, and able to thrive in a highly iterative environment.\n\nThe estimated base salary range for this position is $175,000 to $250,000, which is specific to New York and may change in the future. Millennium pays a total compensation package which includes a base salary, discretionary performance bonus, and a comprehensive benefits package. When finalizing an offer, we take into consideration an individual’s experience level and the qualifications they bring to the role to formulate a competitive total compensation package.","description_format":"text","description_chars":5229,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Hedge Funds & Alternative Investments"],"lifecycle":[{"event":"open","at":"2026-09-26T12:48:45Z"}],"liveness":{"score":5,"band":"cold","label":"Long shot","p_open":1,"p_active":0.173,"p_room":0.28,"age_days":167,"expected_fill_days":31,"reasons":["conf:0","stale_co","velocity","win:tail","crowd:brand"],"computed_at":"2026-09-27T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/millennium-management-feature-framework-engineer","json_url":"https://alion.io/job/millennium-management-feature-framework-engineer.json","meta":{"generated_at":"2026-09-28T00:43:02Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":266,"day_limit":5000,"remaining_today":4734,"minute_limit":60,"resets_at":"2026-09-29T00:00:00Z"}}}
