Founded in 1999, Geneva Trading is a premier global principal trading firm with strategically located offices in Chicago, Dublin, and London.

Our nimble organizational structure and entrepreneurial spirit attract top-tier talent with a passion for innovation, laying the foundation and driving our consistent success in the industry.
Geneva Trading is seeking a Mid-Level System Engineer to join our Core Infrastructure team in Chicago. This is a high-impact role where you will manage the intersection of elite hardware, Linux optimization, and low-latency networking. You will be responsible for ensuring our global trading platform remains performant, resilient, and highly automated.
Key Responsibilities
  • Linux Infrastructure: Provision, configure, and maintain high-performance Red Hat/CentOS/Ubuntu environments.
  • Automation & Orchestration: Build and maintain Infrastructure as Code (IaC) pipelines using Ansible, Terraform, or SaltStack.
  • System Tuning: Fine-tune BIOS, kernel settings, and NICs (Solarflare/Mellanox) to squeeze every microsecond out of the stack.
  • Network Integration: Collaborate with the Network Engineering team to manage high-bandwidth, low-latency trading paths.
  • Monitoring: Proactively monitor system health and latency metrics using Prometheus, Grafana, or Telegraf.
  • Hardware Lifecycle: Manage the deployment and troubleshooting of enterprise-grade bare-metal servers (Dell, HP, Supermicro).
Soft Skills & Communication
  • Crisis Composure: Ability to remain calm and focused during high-volatility market events or system outages.
  • Trader Interaction: Translate complex technical issues into concise updates for non-technical stakeholders (Traders and Quants) in real-time.
  • Collaboration: A proactive communicator who documents "post-mortems" and shares knowledge across the engineering team to prevent recurring issues.
Required Skills & Qualifications
  • Advanced Linux: Deep knowledge of the Linux kernel, system internals, and performance profiling tools.
  • Scripting: Strong proficiency in Python or Bash for building tools and automating workflows.
  • Server Architecture: Experience with modern server hardware, including CPU pinning, NUMA, and PCIe optimization.
Preferred Qualifications
  • Certifications: CCNA (Cisco Certified Network Associate) or equivalent networking knowledge.
  • HFT Experience: Previous experience in a high-frequency trading or high-growth fintech environment.
  • Low-Latency Tech: Exposure to kernel bypass (Onload), PTP (Precision Time Protocol), or FPGA integration.

Compensation
Base Salary Range: $100,000 - $150,000, plus eligibility for a performance-based bonus.
Final compensation will be determined based on the candidate's skills, experience, education, and qualifications. In addition to base salary, Geneva Trading offers a competitive total rewards package, including a comprehensive benefits program.
