Senior Infrastructure & Reliability Engineer (AWS & Low Latency Trading Platform)

Описание

Rock Bund Capital is a proprietary trading firm in the cryptocurrency industry, processing over 15 million transactions daily across major CEx and DEx. The firm is seeking a hands-on Senior Infrastructure & Reliability Engineer to architect, optimize, and maintain their core execution infrastructure, spanning enterprise AWS cloud architecture, bare-metal low-latency networking, and Linux kernel performance tuning. This role involves end-to-end technical ownership for global trading networks, host server performance, and AWS hybrid cloud connectivity, and serving as a primary escalation point for complex production incidents.

Responsibilities

• Architect, maintain, and troubleshoot physical and logical networks across global co-location facilities (Equinix, CME, etc.) and direct exchange feeds
• Manage and debug complex routing and switching protocols, including BGP, RSTP/STP, and Multicast
• Oversee and validate ultra-precise time synchronization setups, including hardware timestamping, Boundary/Transparent clocks, and network QoS
• Diagnose site-to-site encryption and tunnel connectivity for secure broker and exchange lines
• Analyze latency, jitter, and packet drop issues using interface counters, routing diagnostics, and packet capture tools
• Independently design and manage multi-account AWS environments using AWS Organizations, RAM (Resource Access Manager), and account-level security models
• Take direct engineering ownership of AWS Direct Connect, Transit Gateway, and hybrid VPC routing tables
• Develop Infrastructure-as-Code pipelines for reproducible cloud and hybrid deployments
• Perform low-latency host optimization, including CPU isolation, CPU affinity/pinning, C-state/P-state management, and kernel bypass
• Establish empirical measurement frameworks to benchmark, test, and mathematically validate host tuning improvements in production
• Execute structured, step-by-step root-cause analysis for complex production outages across hardware, network, and application layers
• Establish telemetry, metric collection, and alerting frameworks across cloud and on-prem assets

Requirements

• 5+ years of experience in low-latency infrastructure, systems engineering, or SRE supporting electronic trading platforms (buy-side prop/hedge fund preferred, or low-latency sell-side execution desks)
• Hands-on mastery of BGP path selection, Multicast routing, PTP timing, and IPSec VPNs
• Ability to explain protocol mechanics and troubleshoot down to hardware interface counters
• Proven experience independently provisioning and troubleshooting AWS Direct Connect, Transit Gateway, and multi-account AWS Organizations
• Practical experience with Linux kernel tuning and latency validation
• Proficiency in Terraform and shell/Python scripting for infrastructure automation
• Demonstrated ability to systematically isolate network and system failures using protocol analyzers, route tables, and hardware counters
• Fluency in both English and Mandarin Chinese is required to communicate effectively with colleagues from different locations

Nice to have

• Hands-on experience with FIX, exchange connectivity, and crypto APIs
• Familiarity with container orchestration and low-latency storage architectures

We offer

• Competitive remuneration package
• Meritocratic culture where accomplishments are rewarded
• Fast paced and result-oriented with a flat structure
• Teams collaborate in a casual working environment
• Excellent exposure to the digital asset ecosystem and the latest market insight
• Great career development opportunities
