Senior Lead Infrastructure Engineer

About the role

As a Lead Infrastructure Engineer within the Electronic Trading Service at JPMorgan Chase, you will leverage broad, cross-disciplinary expertise spanning low-latency software, network/platform engineering, and the end-to-end electronic trading stack across Investment Banking Markets (FICC and Equities). You will pair deep domain knowledge of trading verticals and high-level execution strategies (e.g., agency execution, market making, hedging, and liquidity-seeking/impact-minimizing routing) with a strong understanding of core market components—including real-time market data (L1/L2, multicast feed-handling, normalization and distribution), venue connectivity, and exchange/order semantics (order types, time-in-force, throttles/limits, and drop-copy/clearing flows).

The successful candidate will have hands-on experience using IXIA to validate performance and traffic behaviour under realistic market-data and order-entry patterns—characterizing throughput, latency, jitter, microburst behaviour, and packet loss—and will hold an active network platform certification (e.g., Cisco, Juniper, Arista, or equivalent).

Responsibilities

• Develop and design the architecture for electronic trading systems, ensuring scalability, reliability, and performance to meet trading requirements.
• Apply deep technical expertise and problem-solving methodologies focused on analyzing complex data and systems, anticipating issues, and finding ways to mitigate risk.
• Work with other platforms to architect and implement changes required to resolve issues and modernize the organization and its technology processes.
• Maintain detailed documentation of system architecture, configurations, and changes, and provide regular reports on system performance and issues.
• Act as the escalation point during major incidents for your application and demonstrate the skills to identify and solve issues quickly to avoid financial losses.
• Be responsible for infrastructure engineering in accordance with business requirements.
• Execute work according to compliance standards, risk and security, and business objectives.
• Consider upstream/downstream system or technical implications and advise on mitigation actions.
• Advise junior engineers and technologists.
• Add to team culture of diversity, opportunity, inclusion, and respect.

Requirements

• Bachelor’s Degree in Computer Science or equivalent.
• Formal training and certification such as CCNP, CCIE or equivalent and 5+ years of applied experience.
• Strong understanding of network architecture, protocols, and technologies (e.g., TCP/IP, multicast, routing, switching).
• Knowledge of one or more areas of infrastructure engineering such as hardware, networking terminology, databases, storage engineering, deployment practices, integration, automation, scaling, resilience, or performance assessments.
• Experience in network architecture, systems engineering, or a related field, within the financial services industry.
• Ability to utilize network automation tools and scripting languages (e.g., Python, Ansible) to automate network tasks and configurations.
• Deep technical knowledge across multiple domains including cloud technologies.
• Design, configure, and manage routing, switching infrastructure including load balancers, to ensure efficient distribution of network traffic.
• Ability to adapt to a fast-paced and dynamic trading environment, with a willingness to learn and implement new technologies.
• Maintain a thorough understanding of basic and advanced concepts in the fields/products/tools of:
  • Network system architecture (processor, ASIC, FPGA, port capabilities, packet forwarding, buffers, etc.);
  • Network routing protocols: Multicast, PIM & IGMP;
  • IP packet analysis using Wireshark;
  • Arista, Cisco, F5 and Fortinet product range.

Preferred Qualifications

• Exposure to managing budgets.
• Familiarity with financial markets, trading platforms, and electronic trading systems.
• Understanding of market data feeds and exchange connectivity.
• Understand deeply network design, implementation, and maintenance, and manage complex network environments to ensure the reliability, performance, and security of the trading infrastructure.
• Configure and manage Cisco routers and switches with proficiency, including knowledge of IOS and NX-OS.
• Demonstrate expertise in Arista’s EOS and experience with Arista’s low latency switching solutions.
• Comprehend in-depth network protocols such as BGP, FHRP, and multicast.
