The posting

Who We Are

Founded in 2019, Rock Bund Capital is a proprietary trading firm deeply committed to shaping the future of the cryptocurrency industry. We have an average daily trading volume reaching $1 billion and peak daily trading volume of $9 billion USD. We process over 15 million transactions daily, trading more than 1,000 symbols across major CEx and DEx.

Our teams bridge traditional finance, quantitative research, and high-performance engineering with native blockchain expertise. Having mastered volatile digital asset markets, we now leverage this technical and market expertise to drive our expansion into Traditional Finance.

We are seeking a hands-on Senior 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

Low-Latency Network Engineering & Co-Lo Infrastructure

  • 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.

Enterprise AWS & Hybrid Cloud Architecture

  • 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.

Linux Kernel & Host Performance Tuning

  • 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.

Why Join Us

  • Competitive remuneration package and a 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

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
