Head of High-Frequency Market Data Engineering

We’re seeking someone to lead the High-Frequency Market Data Engineering function supporting our hedge fund and market-making businesses. This is a senior technical leadership role accountable for the strategy, architecture, and execution of the firm’s market data platform-from the wire to the strategy, and from live order book construction through long-term historical storage. The successful candidate will own the full lifecycle of ultra-low-latency data consumption, normalization, distribution, and storage across asset classes, and will partner closely with portfolio managers, quantitative researchers, and trading desks whose requirements are demanding, diverse, and constantly evolving., * Vision and Strategy: Define and own the multi-year roadmap for market data engineering, balancing latency, coverage, cost, and resilience

• Execution and Delivery: Convert strategy into delivered systems with clear milestones and measurable latency and reliability targets and own the end-to-end architecture for tick data capture, book building, normalization, and internal distribution
• Exchange Connectivity: Oversee direct exchange and venue connectivity across global markets
• Tick Data and Book Construction: Provide deep technical leadership on low-level tick data constructs: full order book building, level 1/2/3 reconstruction, sequencing and recovery semantics, timestamping accuracy, and the nuances that differ across asset classes
• Hardware and Capture Methodology: Be closely involved with the strategy for hardware-accelerated solutions and precision packet capture - FPGA-based feed handling, NICs and kernel-bypass stacks, hardware timestamping, PTP/clock synchronization, and capture device selection
• Storage and Data Management: Own the strategy and architecture for market data storage end to end
• Engineering Leadership: Build, mentor, and retain a high-caliber engineering organization. Set technical standards, raise the bar on C++ and systems engineering quality, and develop the next layer of leadership

• Extensive experience leading market data or low-latency engineering functions in a hedge fund, proprietary trading, market-making, or exchange/HFT environment, with proven ability to both create and execute technical vision and strategy
• Expertise in C++ for performance-critical, low-latency systems and others like Python for the research-facing surface
• Experience with exchange connectivity: feed handlers, market data protocols, recovery and arbitration, and colocation operations and proven vendor management experience
• Deep knowledge of low-level tick data constructs: order book building, sequencing, packet capture devices and methodologies, and asset-class-specific data semantics
• Experience designing and scaling storage and time-series data solutions for high-volume market data
• Demonstrated success building and leading senior engineering teams along with working through complex and varying user requirements
• Demonstrated experience with hardware-accelerated solutions-FPGA-based feed handling, kernel-bypass networking, hardware timestamping, and clock synchronization (PTP)

• Core Benefits: Fully paid medical and dental insurance premiums for employees and dependents, competitive 401k match, employer-paid life & disability insurance
• Perks: Onsite gyms with laundry service, wellness activities, casual dress, snacks, game rooms
• Learning: Tuition reimbursement, conference and training sponsorship
