We are seeking a hands-onSenior Infrastructure & Reliability Engineer with a background in institutional electronic trading platforms to architect, optimize, and maintain our core execution infrastructure. This role sits at the intersection of enterprise AWS cloud architecture, bare-metal low-latency networking, and Linux kernel performance tuning.
The Role
You will have end-to-end technical ownership for our global trading networks, host server performance, and AWS hybrid cloud connectivity. You will design resilient execution platforms and serve as a primary escalation point for complex, production-level network and system incidents.
We are seeking an engineer who operates at the protocol and packet level—someone who understands system behavior beyond automation playbooks, vendor templates, and high-level concepts.
What You Will Do
- 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.
Production Reliability & Systematic Troubleshooting
- 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.
Who You Are
- 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)
- Deep Networking Depth: 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.
- AWS Hybrid Expertise: Proven experience independently provisioning and troubleshooting AWS Direct Connect, Transit Gateway, and multi-account AWS Organizations.
- Linux Performance Tuning: Practical experience with Linux kernel tuning and latency validation.
- Infrastructure as Code: Proficiency in Terraform and shell/Python scripting for infrastructure automation.
- Root-Cause Methodology: 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
Preferred / Nice-to-Have
- Hands-on experience with FIX, exchange connectivity, and crypto APIs.
- Familiarity with container orchestration and low-latency storage architectures.
